Abstract
Gram Pod borer (Helicoverpa armigera Hubner) is the most imperative constraint in chickpea (Cicer arietinum
L.) production causing severe losses or there may be complete crop failure in spite of several rounds of
insecticidal applications. The present study was designed to investigate the effect of neem application in
controlling Pod borer on six different genotypic varieties (AZ-CM2, AZ-CM4, AZ-CM6, AZ-CM10, AZ-CM12 and
Noor-91). The experiment was designed in a Split-Plot Design with three replicates. Different agronomic traits
were recorded such as plant population, plant height, percentage flowering, physical maturity, number of pod
per plant, infestation of pod borer and yield of chickpea. The results showed that plants treated with neem have
high population (maximum in Noor-91 with 16.8 plants/m2 and minimum in AZ-CM12 with 2.9 plants/m2, plant
height (46.7 cm in AZ-CM4 and 34.7cm in Noor-91), flowering (AZ-CM10 gave 50% flowers after 100.3 days),
physical maturity (AZ-CM4 took maximum time (139.7 days) to attain 90% physical maturity while AZ-CM2 and
AZ-CM4 took only 136.0 days to attain 90% physical maturity), average number of pods (Noor 91 has higher 19.4
and AZ-CM2 has lowest 12.1). Infestation of pod borer and % damage was found lower in neem sprayed plant.
Overall highest yield was observed in plants treated with neem as compared to control and genotype dependent.
It is concluded from the results that neem application has a significant effect in controlling pod borer and this
effect varies genotype to genotype. Noor-91 was found to be more resistant towards pod borer.

Introduction
Chickpea (Cicer arietinum L.) is ranking the second
main legume food obtained by resource-poor cultivars
in the arid and semi-arid regions of the world. The
genus Cicer was originated in South-Eastern Turkey
and reached to other regions of world. It is adapted to
comparatively cooler climates. Globally, cultivation of
chickpea in 45 countries of the world including all the
continents and occupied 12.14 million hectares
cultivated area with the production, of 11.3million
tones (Kumar and Abbo, 2001).
The largest area of adaptation where much
production occurs is the Indian sub-continent
Chickpeas are categorized into two distinct types: the
small-seeded ‘desi’ with brown-coloured seed coat
accounts 90% and the large-seeded cream or beige-
coloured ‘kabuli’ accounts up to 10%. Kabuli
chickpeas are cultivated mostly in Pakistan, Turkey,
Ethiopia, Syria, Spain, Canada, the United States,
Mexico and Portugal (Krishnamurthy et al., 2013).
Chickpea seeds are very nutritious, comprising ~25-
29% protein (Hulse, 1989) while 4-10% fat, 52-71%
carbohydrate, and 10-23% fiber, minerals and
vitamins (Jukanti et al., 2012). Additionally, the seed
protein containing necessary amino acids such as
lysine, methionine, threonine, valine, isolucine and
leucine to provide necessary components of human
diet which are useful for maintains of health and fix
atmospheric nitrogen and improve the soil fertility. It
is a crop with self-pollination having a basic
chromosome number 8 and a 739-Mb genome size
(Varshney et al., 2014).
Due to rapid increase in population with the passage
of time, demands for food grains and usual
proliferation efforts require to be supplemented by
genomics-assisted breeding (GAB) (Varshney et al.,
2013). Agricultural practice improved genotypic traits
which ensure survival of chick pea has been
functional in plant reproduction which incorporate
reserve remobilization (Blum, 2005). It is estimated
from throughout about 90% total yield of chick pea is
obtained from rain-fed areas including arid and semi-
arid regions (Kumar et al., 2001).
In drier and warmer regions of semi-arid tropics of
East Africa, Chickpea is considered as a chief protein
source for the population in arid and semi-arid world
(Kimurto et al., 2013).
Chickpea is cultivated in 45 countries of the world
and covers an area of 11 m ha with yield of 9 million
tones. Kabuli chickpea is generally cultivated in
temperate and subtropical regions and it covers
nearly 10% of the total production of the world.
Chickpea was considered to be an orphan legume for
only a few years ago due to insufficient genomic
assets for implementing GAB. Yet, the accessibility of
chickpea genome sequence information (Varshney et
al., 2013) and extensive genomic resources (Varshney
et al., 2013) have changed the crop into a resource
rich crop like any other main crop species.
H. armigera (Hubner) (Lepidoptera: Noctuidae) which
is Chickpea pod borer (CPB), the main notorious pest of
chickpea which destroy the crop on large scale. It is one
of the most important limiting factors for its production
many regions of the world (Sharma et al., 2005). H.
armigera also causes productivity losses in many
vegetables and crops such as cotton, okra, tomato. About
50-60 % damage was recorded in chickpea due to H.
armigera (Verma et al., 2015).
Larvae of H. armigera causes serious damage to
chickpea crop during the fruiting stage, originally by
appearing on new leaves then shifting to flowers,
young shoots and as a final point entering the pods. A
single larva can damage many pods before reaching
the pupal stage. It is another factor that H. armigera
has developed resistance against conventional
insecticides due to overuse (Kranthi et al., 2002).
Large genetic variation for the different traits has
been reported and the breeder can make use of it to
evade the damage caused by the H. armigera in crop
of chickpea. Therefore, the breeding target should be
identified, characterized and develop genetic
mechanism that confers durable resistance to H.
armigera (Dua et al., 2001).
112 Hussain et al.
Int. J. Biosci. 2016
Improvement of farmers with resistance to H.
armigera might provide a valuable approach in
integrated pest management (IPM) to reduce the
productivity losses of chickpea (Sharma et al., 2005).
The use of pheromone trap + BT + Ha NPV effectively
control pod borer (H. armigera) in chickpea (Kumari
et al., 2015). Studies have been conducted by a
number of researchers on screening of chickpea
varieties for resistance and tolerance against H.
armigera (Rashid et al., 2003; Shafique et al., 2009;
Ali et al., 2016).The aim of the present study was to
control the damage caused by H. armigeraon
important crop chickpea by applying integrated
management to improve the yield of chickpea.
Materials and methods
Site description
The control experiment was conducted at the research
farm, University of Agriculture Faisalabad, while
repeated field experiment and survey was conducted
in Thal Desert in Punjab, Pakistan. Thal desert is
located in District Layyah of Province Punjab,
Pakistan has 305.71 Km length and 112.63 Km
breadth near Jhelum and Indus river sites and goes
up to North in Potohar Plateau.
Climate of Thal is extremely hot during summer
season and temperature rises up to 51.6°C
temperature of arid region and has brown color soil.
The study area is approximately barren and consists
of sandy dunes and forest. Average rainfall is 128 mm
to 178 mm but sometime there is too much less
rainfall and ranges from 2 to 4 years. Therefore, there
is scanty of water in Thal at the depth of 25-90m.
Study area is actually a Rakh under control of Forest
Department.
Preparation of neem extract
Neem Seed Kernel Extract (NSKE 5%), 5 kg of Neem
Seed Kernel (well dried) was ground into powder
form and soaked overnight in 10 liters of water. Next
morning, the solution was stirred with a wooden
plank till it became milky white and was, filtered
through double layer of muslin cloth. The volume
now made up to 100 liters. Thus, the 5% concentrated
solution of NSKE was ready to be sprayed in the fields
(Verma et al., 2015).
Field Survey
A field survey was conducted of Thal. The collection
was mainly done to check the presence of H.
armigera on different hosts and how it shifts from
one host to other hosts (Phenology).
Crops like Peas, Cauliflower, Brinjal, Cabbage and
Chickpea. Weeds like Bathu, Senjietc were also been
observed there but no H. armigera was found there.
Upon digging of soil diapa using pupae of H.
armigera were observed and collected for the
laboratory studies but no active stage of H. armigera
was observed.
From this survey, it can be inferred that the active
stages of H. armigera are absent during that time and
the pupae of H. armigera goes into diapauses due to
low temperature and coldness.
Agronomic Practices
Six genotypes of chickpea viz. Noor-91, AZ-CM-2, AZ-
CM-4, AZ-CM-6, AZ-CM-10, AZ-CM-12 were sown
with hand drill. Land preparation was done by two
cultivations followed by planking.1.5 bags of MAP
(mono-ammonium phosphate) and 1 bag of Urea was
applied as fertilizer. Irrigation was applied 5 days
before crop sowing.
The varieties were sown in a Split-plot Design with
three replications. In one plot the Neem application
would be done and in other plot there would be no
Neem application. The plot size of each replication
was maintained at 20 m x 24.0m (Hossain et al.,
2009). Two light traps and 4 pheromone traps were
installed near the field to trap H. armigera (Hübner)
and other Noctuidae pests.
Estimation of H. armigera Damage
Crop pest scouting was done regularly after 3-4 days
and 10 plants were examined thoroughly from each
plot to check the damage per plant by recording
population per m2, plant height (cm), flowering
(percentage), average number of pods, physical
maturity (percentage), infestation of pod borer
(percentage) and percentage damage.

Maximum height was obtained by AZ-CM4 (46.7 cm)
followed by AZ-CM12 which is 44.9 cm. The lowest
height was attained by Noor-91 (34.7 cm). There was
no significant difference was observed of neem
application on the heights of chickpea cultivars (Fig.
8). Earliest 50 percent flowering was observed in AZ-
CM10. In AZ-CM 10 the 50 percent flowering was
observed in 100.3 days after sowing of crop.
The differences among the days to 50 percent
flowering were non-significant among the cultivars
(Fig. 9). The comparison of 90 percent physical
maturity of different chickpea cultivars in neem
treated and untreated plots.
The differences among the cultivars of chickpea in
neem treated and untreated plots were found non-
significant. AZ-CM4 took maximum time (139.7 days)
to attain 90 percent physical maturity, while AZ-CM2
and AZ-CM4 took only 136.0 days to attain 90
percent physical maturity.
There was no significant difference was observed of
neem application on physical maturity (Fig. 10).
Highest average number of pods were found on Noor-
91 (19.4) followed by AZ-CM12 (18.4) and AZ-CM6
(14.7), also indicating that there are significant
difference in pod number in neem treated and
untreated plots (Fig. 11).
Highest population per plant were observed in AZ-
CM12 (3.0 larva) followed by AZ-CM2 (2.2 larva) and
AZ-CM 4 (2.1 larva). There was a significant impact of
neem application in reducing the population of pod
borer (Fig. 12). Most susceptible variety against the
infestation of pod borer was Noor-91 (34.3 percent).
After Noor-91 the highest infestation was observed in
AZ-CM6 (29.1 percent) followed by AZ-CM12 (26.1
percent). The lowest infestation was observed in the
AZ-CM10 (19.0 percent).
There was a significant reduction of infestation in
Neem implicated plots (Fig. 13). Highest yield was
obtained from Noor-91 at the rate of 1115.4 kg per ha.
AZ-CM12 showed good potential and had an
estimated yield of 1073.6 kg per ha.
The lowest yield was obtained in AZ-CM2 654.0 kg
per ha. There was a significant decrease in yield in all
the varieties were Neem was not applied (Fig. 14).
This study will be continuing around the year to
monitor their population and behavior.

Discussion
Chickpea, C. arietinum L. is an important pulse crop
in Pakistan, it is mostly grown in rainfed and irrigated
areas of the Punjab and covers an area of 1.11 m ha
with a grain production of 475 thousand tons per
annum (Anonymous et al., 2008). Pod borer, H.
armigera (Hub.) is a key pest and a prominent
limiting factor in the successful cultivation of
chickpea (Lateef et al., 1985). The financial loss due
to H. armigera harm was expected up to 2030
million rupees per annum in chickpea (Lal et al.,
1985). Controlling type of harmful pest of chickpea
has proved to be very intricate; mainly in the most
recent decade as insecticide resistance has increased
(Armes et al., 1993).
The application of neem extract increased the
emergence of chickpea plants as compared to control.
Among the genotypes, Noor-91 has maximum
population with16.8 plants/m2. Similarly height of
the plant was also found higher in neem treated
plants. Preliminary outcome propose that there are
high levels of preservative genetic variation for the
capability to nourish on the moderately resistant
chickpea being maintained in the population as
presented by (Fitt and Cotter, 2005). Though the
modes of resistance or vulnerability might be
genotype based. Different nutritive values of host
plants may also manipulate the rate of growth of H.
armigera larvae, thus affecting the population
dynamics of this pest.
The given research exactly matches with the findings
of (Hemati, Naseri, Ganbalani, Dastjerdi, and
Golizadeh, 2012). Earliest 50% flowering was
observed in Noor-91 after 102.3 days comparison to
other genotypes. The results were in agreement with
consequences obtained in 28 diallel trials conducted
at ICRISAT representing that days to 50% flowering
was mostly under additive inheritance and highly
predictable (Singh et al. 1992a). In neem applied
plant, earliest 90% physical maturity was seen and
among the varieties, AZ-CM2 90% matured after
136.3 days. Our results relates with the findings of
Yelshetty et al. (1996) who compared the percentage
pod damage at maturity of each trial with that of the
control and transformed to pest susceptibility rating
(PSR) on a scale of 1 to 9). The lower PSR values
represented the lower level of pod borer attack on
genotypes and better tolerance to pod borer. There
was a significant impact of neem application in
reducing the population of pod borer. On an average,
30 to 40 percent pods were found to be damaged by
pod borer with an average of 400 kg/ha grain loss. In
favorable condition, pod damage goes up-to 90-95
percent.
Earlier reports representing the significance of
variances for number of pods per plant relates with
the investigations made (Singh et al. (1992b) and
Yoshida and Shanower (2000) who recommended
that a growth inhibitor or anti-feadent material or
both existed in the resistant genotypes.
116 Hussain et al.
Int. J. Biosci. 2016
The larval survival, larval weight, pupal weights,
pupation and adult appearance were constantly lower
in the resistant genotypes than the vulnerable ones
and the standard diet.
Overall yield of chickpea was found to be higher in neem
treated plants as compared to control. There was a
significant decrease in yield in all the varieties were
neem was not applied. In spite of the pest hit in the
season, there was an improvement in production when
genotypes with resistance modes were planted. The
seasonal discrepancies in yield losses pragmatic may
also be credited to pest prevalence and genetic
composition of arrays such type of attempts agreed with
the results of Hossain(2009) and Rajput et al., 2003).
Orientation and settling, feeding, metabolism of
ingested food, growth, survival, fecundity, oviposition
and hatching of eggs are the most important response
categories of insects that determine their successful
invasion and utilization of host plants [Saxena, 1969].
The establishment of insects and their consequential
damage on the host plant may be reduced or affected
by disruption of one or more of these important
responses. Dried neem leaves and seed cakes were used
for long time in India to protect crops from pests.
Previous studies reported natural plant products which
possess multitudes of effects such as repellence,
feeding deterrence, growth and development inhibitory
and other effects have some potential for the
management of pests (Klocke et al., 1989).
Nardo et al. (1997) reported that the substance in
aqueous extracts of leaves and neem seeds inhibit the
development of larvae, egg fertility and exerts repellent
or toxic effect on B. tabaci. According to Viňuela et al.
(2003), azadirachtin has effects similar to that of
diflubenzuron (DIMILIN 25 WP, Agr Evo, Valencia,
Spain) with similar actions in juvenile hormone
blocking insect metamorphosis. It inhibits the growth
that affects spawning (Bruce et al., 2004) and molting
and larval development (Islam et al., 2007).
Grain productivity was mainly under the control of
dominant gene action which have a tendency to
enhance or reduce grain production are more or less
present in equal frequency in parents of the early
maturity group while in medium and late maturity
groups they were relatively in imbalanced frequency
(Gowda, Ramesh, Chandra, and Upadhyaya, 2005).
Preservative gene action governed the inheritance of
resistance to H. armigera whereas non-additive type
of gene action was main for inheritance of antibiosis
constituent of resistance (larval survival and larval
weight) and grain yield (Narayanamma et al., 2013).
The presented consequences were in agreement with
(Kumar et al., 2001) who reported that non-additive
genetic effects are of chief import for yield. Moreover
plant resistance to pests is an economically and
ecologically favorite option to other pest management
strategies. Host plant resistance is simple, expedient
and contemptible and generally works well in
arrangement with new forms of pest management
while it can have severe implications for the
effectiveness of some alternative pest management
strategies.
In some cases, serious inappropriateness does occur
between natural plant resistance and other pest
management approaches, consequently there is a
great need to realize completely the mechanisms
concerned in resistance to guarantee that antagonistic
effects can be avoided (Stevenson et al., 2005).
Farmers mainly rely on insecticides for the
management of H. armigera.
The chickpea genotypes identified as constant in
resistance to H. armigera harm can be used in
further breeding programs to develop resistant
varieties. Diallel analysis revealed the gene action for
H. armigera resistance and suitable breeding
technique can be preferred to develop resistant
varieties. The main point of view of given research
was to assess the relative importance of various
Genomic traits that might add to yield stability for
further breeding efforts in chickpea.
117 Hussain et al.
Int. J. Biosci. 2016
The results support to conclude safely that the pod
infestation, larval population and grain yield could be
used as selection criteria of a resistant genotype as the
fundamental part of management program against H.
armigera.
Conclusion
Several studies have been conducted and valuable
information has been generated for a targeted
chickpea breeding program to improve the
productivity. Very little effort had been made toward
identification of other potentially important traits
apart from the root traits yield improvements in
chickpea. Such type of researches mainly focused on a
single or a few target genomic traits from the last
decade. Consequently such genotypes have a valuable
resource of borer resistance that could be utilized
either as varieties or by using them in hybridization to
develop high yielding and pod borer resistant variety
as an element of integrated pest management
strategy. To attain this, training in modern plant
breeding skills and development integrated breeding
strategies and sharing of information and capability
among mutual associates, particularly in developing
countries with inadequate infrastructure and human
resources are the necessitate of the age.

The present study was designed to investigate the effect of neem application in controlling Pod borer on six different genotypic varieties (AZ-CM2, AZ-CM4, AZ-CM6, AZ-CM10, AZ-CM12 and Noor-91). The experiment was designed in a Split-Plot Design with three replicates. Different agronomic traits were recorded such as plant population, plant height, percentage flowering, physical maturity, number of pod per plant, infestation of pod borer and yield of chickpea. The results showed that plants treated with neem have high population (maximum in Noor-91 with 16.8 plants/m2 and minimum in AZ-CM12 with 2.9 plants/m2, plant height (46.7 cm in AZ-CM4 and 34.7cm in Noor-91), flowering (AZ-CM10 gave 50% flowers after 100.3 days), physical maturity (AZ-CM4 took maximum time (139.7 days) to attain 90% physical maturity while AZ-CM2 and AZ-CM4 took only 136.0 days to attain 90% physical maturity), average number of pods (Noor 91 has higher 19.4 and AZ-CM2 has lowest 12.1). Infestation of pod borer and % damage was found lower in neem sprayed plant. Overall highest yield was observed in plants treated with neem as compared to control and genotype dependent. It is concluded from the results that neem application has a significant effect in controlling pod borer and this effect varies genotype to genotype. Noor-91 was found to be more resistant towards pod borer. * Corresponding Author: Mumtaz Hussain  shafiquebot@yahoo.com International Journal of Biosciences | IJB | ISSN: 2220-6655 (Print) 2222-5234 (Online) http://www.innspub.net Vol. 9, No. 2, p. 110-119, 2016
  • 2. 111 Hussain et al. Int. J. Biosci. 2016 Introduction Chickpea (Cicer arietinum L.) is ranking the second main legume food obtained by resource-poor cultivars in the arid and semi-arid regions of the world. The genus Cicer was originated in South-Eastern Turkey and reached to other regions of world. It is adapted to comparatively cooler climates. Globally, cultivation of chickpea in 45 countries of the world including all the continents and occupied 12.14 million hectares cultivated area with the production, of 11.3million tones (Kumar and Abbo, 2001). The largest area of adaptation where much production occurs is the Indian sub-continent Chickpeas are categorized into two distinct types: the small-seeded ‘desi’ with brown-coloured seed coat accounts 90% and the large-seeded cream or beige- coloured ‘kabuli’ accounts up to 10%. Kabuli chickpeas are cultivated mostly in Pakistan, Turkey, Ethiopia, Syria, Spain, Canada, the United States, Mexico and Portugal (Krishnamurthy et al., 2013). Chickpea seeds are very nutritious, comprising ~25- 29% protein (Hulse, 1989) while 4-10% fat, 52-71% carbohydrate, and 10-23% fiber, minerals and vitamins (Jukanti et al., 2012). Additionally, the seed protein containing necessary amino acids such as lysine, methionine, threonine, valine, isolucine and leucine to provide necessary components of human diet which are useful for maintains of health and fix atmospheric nitrogen and improve the soil fertility. It is a crop with self-pollination having a basic chromosome number 8 and a 739-Mb genome size (Varshney et al., 2014). Due to rapid increase in population with the passage of time, demands for food grains and usual proliferation efforts require to be supplemented by genomics-assisted breeding (GAB) (Varshney et al., 2013). Agricultural practice improved genotypic traits which ensure survival of chick pea has been functional in plant reproduction which incorporate reserve remobilization (Blum, 2005). It is estimated from throughout about 90% total yield of chick pea is obtained from rain-fed areas including arid and semi- arid regions (Kumar et al., 2001). In drier and warmer regions of semi-arid tropics of East Africa, Chickpea is considered as a chief protein source for the population in arid and semi-arid world (Kimurto et al., 2013). Chickpea is cultivated in 45 countries of the world and covers an area of 11 m ha with yield of 9 million tones. Kabuli chickpea is generally cultivated in temperate and subtropical regions and it covers nearly 10% of the total production of the world. Chickpea was considered to be an orphan legume for only a few years ago due to insufficient genomic assets for implementing GAB. Yet, the accessibility of chickpea genome sequence information (Varshney et al., 2013) and extensive genomic resources (Varshney et al., 2013) have changed the crop into a resource rich crop like any other main crop species. H. armigera (Hubner) (Lepidoptera: Noctuidae) which is Chickpea pod borer (CPB), the main notorious pest of chickpea which destroy the crop on large scale. It is one of the most important limiting factors for its production many regions of the world (Sharma et al., 2005). H. armigera also causes productivity losses in many vegetables and crops such as cotton, okra, tomato. About 50-60 % damage was recorded in chickpea due to H. armigera (Verma et al., 2015). Larvae of H. armigera causes serious damage to chickpea crop during the fruiting stage, originally by appearing on new leaves then shifting to flowers, young shoots and as a final point entering the pods. A single larva can damage many pods before reaching the pupal stage. It is another factor that H. armigera has developed resistance against conventional insecticides due to overuse (Kranthi et al., 2002). Large genetic variation for the different traits has been reported and the breeder can make use of it to evade the damage caused by the H. armigera in crop of chickpea. Therefore, the breeding target should be identified, characterized and develop genetic mechanism that confers durable resistance to H. armigera (Dua et al., 2001).
  • 3. 112 Hussain et al. Int. J. Biosci. 2016 Improvement of farmers with resistance to H. armigera might provide a valuable approach in integrated pest management (IPM) to reduce the productivity losses of chickpea (Sharma et al., 2005). The use of pheromone trap + BT + Ha NPV effectively control pod borer (H. armigera) in chickpea (Kumari et al., 2015). Studies have been conducted by a number of researchers on screening of chickpea varieties for resistance and tolerance against H. armigera (Rashid et al., 2003; Shafique et al., 2009; Ali et al., 2016).The aim of the present study was to control the damage caused by H. armigeraon important crop chickpea by applying integrated management to improve the yield of chickpea. Materials and methods Site description The control experiment was conducted at the research farm, University of Agriculture Faisalabad, while repeated field experiment and survey was conducted in Thal Desert in Punjab, Pakistan. Thal desert is located in District Layyah of Province Punjab, Pakistan has 305.71 Km length and 112.63 Km breadth near Jhelum and Indus river sites and goes up to North in Potohar Plateau. Climate of Thal is extremely hot during summer season and temperature rises up to 51.6°C temperature of arid region and has brown color soil. The study area is approximately barren and consists of sandy dunes and forest. Average rainfall is 128 mm to 178 mm but sometime there is too much less rainfall and ranges from 2 to 4 years. Therefore, there is scanty of water in Thal at the depth of 25-90m. Study area is actually a Rakh under control of Forest Department. Preparation of neem extract Neem Seed Kernel Extract (NSKE 5%), 5 kg of Neem Seed Kernel (well dried) was ground into powder form and soaked overnight in 10 liters of water. Next morning, the solution was stirred with a wooden plank till it became milky white and was, filtered through double layer of muslin cloth. The volume now made up to 100 liters. Thus, the 5% concentrated solution of NSKE was ready to be sprayed in the fields (Verma et al., 2015). Field Survey A field survey was conducted of Thal. The collection was mainly done to check the presence of H. armigera on different hosts and how it shifts from one host to other hosts (Phenology). Crops like Peas, Cauliflower, Brinjal, Cabbage and Chickpea. Weeds like Bathu, Senjietc were also been observed there but no H. armigera was found there. Upon digging of soil diapa using pupae of H. armigera were observed and collected for the laboratory studies but no active stage of H. armigera was observed. From this survey, it can be inferred that the active stages of H. armigera are absent during that time and the pupae of H. armigera goes into diapauses due to low temperature and coldness. Agronomic Practices Six genotypes of chickpea viz. Noor-91, AZ-CM-2, AZ- CM-4, AZ-CM-6, AZ-CM-10, AZ-CM-12 were sown with hand drill. Land preparation was done by two cultivations followed by planking.1.5 bags of MAP (mono-ammonium phosphate) and 1 bag of Urea was applied as fertilizer. Irrigation was applied 5 days before crop sowing. The varieties were sown in a Split-plot Design with three replications. In one plot the Neem application would be done and in other plot there would be no Neem application. The plot size of each replication was maintained at 20 m x 24.0m (Hossain et al., 2009). Two light traps and 4 pheromone traps were installed near the field to trap H. armigera (Hübner) and other Noctuidae pests. Estimation of H. armigera Damage Crop pest scouting was done regularly after 3-4 days and 10 plants were examined thoroughly from each plot to check the damage per plant by recording population per m2, plant height (cm), flowering (percentage), average number of pods, physical maturity (percentage), infestation of pod borer (percentage) and percentage damage.
  • 4. 113 Hussain et al. Int. J. Biosci. 2016 Results Different field observations are represented in Fig. 1 to 6. Plant population per meter square of different chickpea cultivars in Neem sprayed and unsprayed cultivars was recorded and maximum plant population per m2 was observed in Noor-91 with 16.8 plants/m2. AZ-CM10 had population of 14.7 plants/m2 followed by AZ-CM6 with 14.2 plants/m2. There was no statistical difference of neem application on the emergence of chickpea plants. But, generally high emergence was observed in neem treated plots (Fig.7). Fig. 1. Pheromone trap installed in IPM Plot. Fig. 2. Plant Affected by Ascochyta Blight. Fig. 3.

  • 5. 114 Hussain et al. Int. J. Biosci. 2016 Maximum height was obtained by AZ-CM4 (46.7 cm) followed by AZ-CM12 which is 44.9 cm. The lowest height was attained by Noor-91 (34.7 cm). There was no significant difference was observed of neem application on the heights of chickpea cultivars (Fig. 8). Earliest 50 percent flowering was observed in AZ- CM10. In AZ-CM 10 the 50 percent flowering was observed in 100.3 days after sowing of crop. The differences among the days to 50 percent flowering were non-significant among the cultivars (Fig. 9). The comparison of 90 percent physical maturity of different chickpea cultivars in neem treated and untreated plots. The differences among the cultivars of chickpea in neem treated and untreated plots were found non- significant. AZ-CM4 took maximum time (139.7 days) to attain 90 percent physical maturity, while AZ-CM2 and AZ-CM4 took only 136.0 days to attain 90 percent physical maturity. There was no significant difference was observed of neem application on physical maturity (Fig. 10). Highest average number of pods were found on Noor- 91 (19.4) followed by AZ-CM12 (18.4) and AZ-CM6 (14.7), also indicating that there are significant difference in pod number in neem treated and untreated plots (Fig. 11). Highest population per plant were observed in AZ- CM12 (3.0 larva) followed by AZ-CM2 (2.2 larva) and AZ-CM 4 (2.1 larva). There was a significant impact of neem application in reducing the population of pod borer (Fig. 12). Most susceptible variety against the infestation of pod borer was Noor-91 (34.3 percent). After Noor-91 the highest infestation was observed in AZ-CM6 (29.1 percent) followed by AZ-CM12 (26.1 percent). The lowest infestation was observed in the AZ-CM10 (19.0 percent). There was a significant reduction of infestation in Neem implicated plots (Fig. 13). Highest yield was obtained from Noor-91 at the rate of 1115.4 kg per ha. AZ-CM12 showed good potential and had an estimated yield of 1073.6 kg per ha. The lowest yield was obtained in AZ-CM2 654.0 kg per ha. There was a significant decrease in yield in all the varieties were Neem was not applied (Fig. 14). This study will be continuing around the year to monitor their population and behavior. Fig. 7.

Pod borer, H. armigera (Hub.) is a key pest and a prominent limiting factor in the successful cultivation of chickpea (Lateef et al., 1985). The financial loss due to H. armigera harm was expected up to 2030 million rupees per annum in chickpea (Lal et al., 1985). Controlling type of harmful pest of chickpea has proved to be very intricate; mainly in the most recent decade as insecticide resistance has increased (Armes et al., 1993). The application of neem extract increased the emergence of chickpea plants as compared to control. Among the genotypes, Noor-91 has maximum population with16.8 plants/m2. Similarly height of the plant was also found higher in neem treated plants. Preliminary outcome propose that there are high levels of preservative genetic variation for the capability to nourish on the moderately resistant chickpea being maintained in the population as presented by (Fitt and Cotter, 2005). Though the modes of resistance or vulnerability might be genotype based. Different nutritive values of host plants may also manipulate the rate of growth of H. armigera larvae, thus affecting the population dynamics of this pest. The given research exactly matches with the findings of (Hemati, Naseri, Ganbalani, Dastjerdi, and Golizadeh, 2012). Earliest 50% flowering was observed in Noor-91 after 102.3 days comparison to other genotypes. The results were in agreement with consequences obtained in 28 diallel trials conducted at ICRISAT representing that days to 50% flowering was mostly under additive inheritance and highly predictable (Singh et al. 1992a). In neem applied plant, earliest 90% physical maturity was seen and among the varieties, AZ-CM2 90% matured after 136.3 days. Our results relates with the findings of Yelshetty et al. (1996) who compared the percentage pod damage at maturity of each trial with that of the control and transformed to pest susceptibility rating (PSR) on a scale of 1 to 9). The lower PSR values represented the lower level of pod borer attack on genotypes and better tolerance to pod borer. There was a significant impact of neem application in reducing the population of pod borer. On an average, 30 to 40 percent pods were found to be damaged by pod borer with an average of 400 kg/ha grain loss. In favorable condition, pod damage goes up-to 90-95 percent. Earlier reports representing the significance of variances for number of pods per plant relates with the investigations made (Singh et al. (1992b) and Yoshida and Shanower (2000) who recommended that a growth inhibitor or anti-feadent material or both existed in the resistant genotypes.
  • 7. 116 Hussain et al. Int. J. Biosci. 2016 The larval survival, larval weight, pupal weights, pupation and adult appearance were constantly lower in the resistant genotypes than the vulnerable ones and the standard diet. Overall yield of chickpea was found to be higher in neem treated plants as compared to control. There was a significant decrease in yield in all the varieties were neem was not applied. In spite of the pest hit in the season, there was an improvement in production when genotypes with resistance modes were planted. The seasonal discrepancies in yield losses pragmatic may also be credited to pest prevalence and genetic composition of arrays such type of attempts agreed with the results of Hossain(2009) and Rajput et al., 2003). Orientation and settling, feeding, metabolism of ingested food, growth, survival, fecundity, oviposition and hatching of eggs are the most important response categories of insects that determine their successful invasion and utilization of host plants [Saxena, 1969]. The establishment of insects and their consequential damage on the host plant may be reduced or affected by disruption of one or more of these important responses. Dried neem leaves and seed cakes were used for long time in India to protect crops from pests. Previous studies reported natural plant products which possess multitudes of effects such as repellence, feeding deterrence, growth and development inhibitory and other effects have some potential for the management of pests (Klocke et al., 1989). Nardo et al. (1997) reported that the substance in aqueous extracts of leaves and neem seeds inhibit the development of larvae, egg fertility and exerts repellent or toxic effect on B. tabaci. According to Viňuela et al. (2003), azadirachtin has effects similar to that of diflubenzuron (DIMILIN 25 WP, Agr Evo, Valencia, Spain) with similar actions in juvenile hormone blocking insect metamorphosis. It inhibits the growth that affects spawning (Bruce et al., 2004) and molting and larval development (Islam et al., 2007). Grain productivity was mainly under the control of dominant gene action which have a tendency to enhance or reduce grain production are more or less present in equal frequency in parents of the early maturity group while in medium and late maturity groups they were relatively in imbalanced frequency (Gowda, Ramesh, Chandra, and Upadhyaya, 2005). Preservative gene action governed the inheritance of resistance to H. armigera whereas non-additive type of gene action was main for inheritance of antibiosis constituent of resistance (larval survival and larval weight) and grain yield (Narayanamma et al., 2013). The presented consequences were in agreement with (Kumar et al., 2001) who reported that non-additive genetic effects are of chief import for yield. Moreover plant resistance to pests is an economically and ecologically favorite option to other pest management strategies. Host plant resistance is simple, expedient and contemptible and generally works well in arrangement with new forms of pest management while it can have severe implications for the effectiveness of some alternative pest management strategies. In some cases, serious inappropriateness does occur between natural plant resistance and other pest management approaches, consequently there is a great need to realize completely the mechanisms concerned in resistance to guarantee that antagonistic effects can be avoided (Stevenson et al., 2005). Farmers mainly rely on insecticides for the management of H. armigera. The chickpea genotypes identified as constant in resistance to H. armigera harm can be used in further breeding programs to develop resistant varieties. Diallel analysis revealed the gene action for H. armigera resistance and suitable breeding technique can be preferred to develop resistant varieties. The main point of view of given research was to assess the relative importance of various Genomic traits that might add to yield stability for further breeding efforts in chickpea.
  • 8. 117 Hussain et al. Int. J. Biosci. 2016 The results support to conclude safely that the pod infestation, larval population and grain yield could be used as selection criteria of a resistant genotype as the fundamental part of management program against H. armigera. Conclusion Several studies have been conducted and valuable information has been generated for a targeted chickpea breeding program to improve the productivity. Very little effort had been made toward identification of other potentially important traits apart from the root traits yield improvements in chickpea. Such type of researches mainly focused on a single or a few target genomic traits from the last decade. Consequently such genotypes have a valuable resource of borer resistance that could be utilized either as varieties or by using them in hybridization to develop high yielding and pod borer resistant variety as an element of integrated pest management strategy. To attain this, training in modern plant breeding skills and development integrated breeding strategies and sharing of information and capability among mutual associates, particularly in developing countries with inadequate infrastructure and human resources are the necessitate of the age.
