Integrated Pest Management (IPM) utilizes various pest control tactics together in a harmonious way to achieve long-term pest control. The key components of IPM include gathering initial information, correctly identifying pests, monitoring pest populations, establishing economic injury levels, record keeping, selecting least-toxic treatment strategies, and evaluating treatments. Cultural, mechanical, biological, and chemical practices are among the pest management tactics used in IPM. The logic and necessity of IPM includes potential economic benefits from reduced pesticide use, environmental benefits from decreased contamination, and knowledge benefits from a better understanding of pests and their management.

Identification – Why is it necessary ?
• To know actual menace
• Scientific name of an organism, literature on the biology of the pest, Interview concerned
farmers on the history of pest , background of the problem,
•
• To determine if the pest is a key pest
A key pest can be an insect, mite, disease, nematode or weed that frequently results in
unacceptable / intolerable damage
• To determine what pest control tactic should be
utilized
Actual methods used to implement the strategies to achieve pest control
• Because incorrect identification can result in
ineffective pest control measures
Time and dose,

16. KEY PEST
Not always all the Insects are pests, but the one
which can cause the most significant damage
An insect, mite, disease, nematode, or weed that
frequently results in unacceptable or intolerable
damage and thus typically requires a control action.
a
ECONOMIC INJURY LEVEL
ECONOMIC THRESHOLD

17. Why it is important to know the life
cycle of the pest ?
• To determine when the
pest is most vulnerable
to apply control
strategies
• To determine if a pest is
approaching at a stage
to pose a potential
damage to a plant
species

18. 3. Monitoring
& its Importance / necessity in IPM?
• To assess the pest situation and determine
what sort of pest activity is occurring
• For decision making
• To predict pest problems before they occur

19. The decision to use a pesticide should be
based on:
• Information obtained from monitoring
• Knowledge of thresholds
• An awareness of potential benefits and risks
associated with a treatment

20. Monitoring methods
VisualCounts Pheromonetraps SweepNets FieldHistroy
Typesofmonitoringmethods

21. Equilibrium Position (EP)
The average population level of an insect species
Economic Threshold (ET)
The population level at which management action should be taken to prevent
the pest from reaching the economic injury level
Economic Injury Level (EIL)
The lowest number of insects that will cause economic damage
Economic Damage (ED)
The amount of pest-caused damage that justifies the cost of applying pest
control measures
4. Establishing Injury Levels are based on
Damage levels

22. The average population level of an insect species (EP).

23. Some Insects are never economic pests - the Equilibrium
position (EP) is below the economic threshold (ET) or
Economic Injury level (EIL)
Example: Neem weevil, Myllocerus tenuicornis
EP

24. Economic threshold (Action threshold)
The pest density or level of damage at which a control measure is
needed to prevent economic loss.
Economic loss
Occurs when the cost of insect damage in terms of yield or quality
exceeds the cost of control.

25. Some insects are occasional pests and must
be controlled at ET or they will reach EIL.
Example: Achaea janata, Polyphagous
defoliator

26. Some insects are regular and serious pests – the
Equilibrium position (EP) is above EIL all the time unless
steps are taken to keep them low.
Example: Sal heartwood borer, Hoplocerambyx spinicornis

27. Aesthetic thresholds
The level at which
a pest causes an
undesirable change
in the appearance
of plant parts

28. 5.Record keeping
Accurate records
related to the insect
pest species and
nature of damage
are amongst the
important
informations for
making a decision
for IPM

29. 6. Criteria for selecting a suitable treatment
strategy Least-toxic treatment approaches
• most likely to exhibit a economic reduction of the pest
population.
• least disruptive of natural controls.
• least hazardous to human health.
• least toxic to non-target organisms
• least damaging to the general environment.
• easiest to carry out effectively.
• most cost effective over both the short and long
terms.

16. Large pruning wounds should be treated
17. For excellent fruit set, pollinizer cultivars should be planted in required
proportion
Important Cultural Controls practices

33. Cultural Controls
Soil working and Nutrition
• Plants with adequate
nutrition can grow
more vigorously,
allowing them to
better tolerate pest
damage or to
compete better with
weeds
• Soil cultivation can kill
insect pests by
exposing them to
sunlight, predators
and injuring them

34. Cultural Controls
Sanitation
• Removal of rubbish, infested or
decaying matter as well as crop
residues from around and in fields
can often eliminate breeding sites
for insect pests
• Using seeds and planting materials
which are free of weed seeds and
diseases

35. Cultural Control
Multiple Cropping / Mixed Cropping
 Growing a variety of crops
together in the
same location:
 Increases the habitat for
pest predators
 Limits the number of food
plants for specific insect
pests
 Discouraging
monocultures

36. Mechanical Control
Practices

37. Important Mechanical Control
Practices
1. Use of various types of mulches (bark chips, geotextiles, etc.) can
suppress weeds and also protect of plants from frost.
2. Pinching off diseased parts can suppress certain plant diseases
3. Hand destruction or removal of insects and egg masses ensures
quick and positive control.
4. Mechanical traps and attractants can be used to trap injurious
insects to lower crop damage
5. A forceful stream of water may dislodge insects such as aphids
and spider mites from foliage and plant stems.
6. Several insecticidal soaps can regularise certain pest populations

practices

40. Plant Resistance control practices
The use of species or varieties of plants that can grow and produce
despite the presence of its key insect pests

41. Regulatory Control
Practices

42. Regulatory Control Practices
“The prevention & Eradication or suppression of
the pests establishment in a limited area by
application of compulsory enactment”.

43. Regulatory Tactics
• Quarantine: limits movement of a pest
• Eradication: must be applied to
relatively small geographic areas
• Suppression: limits pest levels over large
geographic areas

44. Successful plant pest control depends on the successful
blending of many skills, legislative pest control and
other management strategies which may include:
Identification of risk
Prevention of entry
Survey and detection
Eradication
Retardation of spread
Mitigation of losses
Regulatory Control Practices

45. Biological control
Practices

46. Biological control
Predators
Parasites
Parasitoids
Pathogens
The use predators, parasites, parasitoids, pathogens,
and competitors to control pests. Natural enemies of
pests cause mortality; Can maintain pest population at
below-threshold levels

Biological control
• Scientific basis
– Each pest has natural predators, parasites and competitors
– Bring equilibrium predator-prey below the economic
threshold of pest by applying IPM
Long-term solutions
Sustainable
Increase of predatory
populations

49. Types of BC:
• Classical BC : Import natural enemies & establish in
field
• Augmentative releases: Inundative (begin with of a
large number of natural enemies) or Inoculative
(begins with a small number of natural enemies)
releases each season
• Conservation BC: depend upon local natural enemies.
• All these approaches require conservation of natural
enemies to be effective.

50. Conserving natural enemies
Reduce insecticide use;
Use softer chemicals;
Manipulate habitats, e.g.
intercropping.

51. Parasite:
An organism which lives in or on another organism (its
host) and benefits by deriving nutrients at the other's
expense.
A parasite that lives inside of the host body is called an
endoparasite.
Endoparasites include organism such as tapworms,
hookworms and trypanosomes etc.

52. Parasitoids:
An organism that, during its development, lives in or on the body of
a single host individual, eventually killing that individual.
Major characteristics:
They are specialized in their choice of host , smaller than host,
Only the female searches for host. Immatures remain on or in
host; adults are free-living, mobile, and may be predaceous.
Immatures almost always kill host.
Four of the most important groups are:
Ichneumonid wasps
Braconid wasps
Chalcid wasps:
Tachenid flies:
Ichneumonid wasps
Braconid wasps
Chalcid wasps:
Tachenid fiY

53. Predators
Predators are mainly free-living species that
directly consume a large number
of prey during their whole lifetime.
Examples: beetles, true bugs, lacewings,
flies, midges, spiders, wasps, and predatory
mites.
Major characteristics of arthropod predators:
Adults and immatures are often generalists rather than
specialists. they generally are larger than their prey. They kill
or consume many prey.. They may attack immature as well as
adult prey.

54. Birds play an
important role in
controlling white grub,
cut worm, mole cricket
and field cricket
Common insectivorous
birds are black drongo,
house sparrow, cattle
egrets, House crow,
jungle crow, common
myna, bank myna ,
Indian robin and parrot
Bird perches may play an important role to facilitate
predation on harmful insects

55. Entomopathogens
Entomopathogenic viruses
Bacterial pathogens
Fungal pathogens
Microsporidia
Nematodes
Protozoa

56. Types of Entomopathogens
Entomopathogenic viruses:
Viral diseases have been found in 13 insect orders and
most likely occur in all orders.
 DNA Viruses: Baculoviruses (Nuclear polyhedrosis
viruses- NPV and Granuloviruses-GV), Asco-viruses, Irido-
viruses, Parvo-viruses and Pox-viruses.
 RNA Viruses: Reo-viruses (Cytoplasmic polyhedrosis
viruses), Nodaviruses and Tetra-viruses.

57. Entomopathogenic Bacteria:
They can be divided into two broad categories,
non-spore-forming bacteria and spore-forming
bacteria.
Although, most of the species isolated from
diseased insects are spore-forming bacteria in the
genus Bacillus. They are the most important
biological control tool
Types of Entomopathogens

58. Entomopathogenic Fungi:
 Entomopathogenic fungi are able to invade their
insect hosts by penetrating directly through the
cuticle.
The fungal spore first adheres to the cuticle.
 After the body of the dead insect is filled with
mycelia, fruiting structures emerge from the
cadaver and produce infectious spores.
Types of Entomopathogens

59. Beauveria bassiana Metarhizium anisoplae.
Beauveria spp., Lecanicillium spp., Metarhizium spp., Paecilomyces spetc., are some of
the entomopathogenic fungi spp. and are used as biological insecticides
Entomopathogenic
Fungi:

60. Microsporidia:
 The only microsporidian ever registered as a
microbial pesticide is Nosema locustae, a
pathogen of grasshoppers.
 Two other microsporidian species that are
known to control populations of pest insects:
Nosema fumiferanae and Nosema pyrausta.
Types of Entomopathogens

61. Protozoa:
 Protozoa are the most taxonomically diverse group
of insect pathogens.
 Entry into the host is typically by ingestion, but
some can invade through the cuticle.
 Some species may be trans-ovarially transmitted
from infected females to their offspring.
Types of Entomopathogens

62. Nematodes:
Entomopathogenic nematodes enter the host
via natural body openings or through the cuticle.
Effects of nematode parasitism on the hosts
can reduce fecundity, mobility and life span,
behaviour and morphological changes, and
ultimately death of pest.

&
Evolutionary trends
of IPM

80. Basic Principles of IPM
Principle-1: Prevention and Suppression
Principle-2: Monitoring through Professionally qualified advisors
Principle-3: Decision-Making
Principle-4: Non-Toxic Chemical Methods
Principle-5: Pesticide Selection & Reduced Pesticide Use
Principle-6: Anti-Resistance Strategies
Principle-7: Evaluation Monitoring of Harmful Organisms
Principle-8: Intervention
Principle-9: Consideration of Ecosystem
Principle-10: Pest Surveillance

81. Basic Principles of IPM
The main 10 important Principles of IPM are :
Principle 1
Prevention and Suppression
1. Crop rotation and use of adequate cultivation
techniques,
2. Use of resistant/tolerant cultivars,
3. Use of balanced fertilization and liming irrigation,
preventing harmful organisms
4. Enhancement of important beneficial organisms,
5. Selection of appropriate for the location
6. Careful harvesting and
7. Good Hygiene

82. Principle 2
Monitoring through Professionally qualified advisors
1. Harmful organisms must be monitored periodically
by observations in the field through scientifically
sound warning and forecasting systems and
2. Seeking proper advice from professionally qualified
advisors as and when required.
Basic Principles of IPM

83. Principle 3
Decision-Making
Based on the report of the monitoring team one has to
decide whether and when to apply plant protection
measures.
Principle 4
Non-Toxic Chemical Methods
Sustainable biological, and non-toxic chemical methods
must be preferred, over chemical methods, if they
provide satisfactory pest control.
Basic Principles of IPM

84. Principle 5
Pesticide Selection & Reduced Pesticide Use
1. The pesticides applied shall be as specific as possible
for the target pest species and
2. It should have the least side effects on human
health, non-target organisms and the environment.
Basic Principles of IPM

85. Principle 6
Anti-Resistance Strategies
1. Anti-resistance strategies should be applied to maintain the
effectiveness of the pesticidal products.
2. Once the risk of resistance against a plant protection measure
is known, an alternative chemical should be used
3. This may include the use of multiple pesticides with different
modes of action.
Basic Principles of IPM

86. Principle 7
Evaluation Monitoring of Harmful Organisms
This involves determining when and what action is to be taken,
based on all the available information. For example:
•Periodical Crop monitoring for pest and damage thresholds
•Sound record keeping and analysis of past information to
help predict future outcomes;
•Advice and support from experts.
Basic Principles of IPM

87. Principle 8
Intervention
This aims to reduce the effects of economically damaging pest
populations, weeds and disease to acceptable levels.
•This may be by making use of mechanical, biological and
chemical measures.
•It will increase crop profitability especially where presently pest
control is poorly used or ineffective.
•It will help in reducing the severity of pest infestations and
ensure agricultural production is more sustainable
Basic Principles of IPM

88. Principle 9
Consideration of Ecosystem
Control of insect pest population is a function of the ecosystem
itself by means of natural enemies and other factors.
The study of individuals is of prime importance for their biology
behaviour response to other members of the same species and
other organisms in the environment.
The study of individuals offers a potent method for this analysis
of population change.
Basic Principles of IPM

89. Principle 10
Pest Surveillance
Pest Surveillance and forecasting is a vital part in the IPM.
It means constant observation of an insect pest and its damage
after application of control strategy and comprises of three basic
components
1. Determination of the reduction in level of incidence of the
pest species after application of control strategy.
2. Determination of reduction of loss the incidence after
application of control strategy.
3. Determination of increase in economic benefits after
application of control strategy.
Basic Principles of IPM

the future. In fact, even in the same time period, people have several different
ideas about how pest management could be more advanced.

98. Ecological Basis
of IPM

99. Ecological Basis of IPM
The Ecological Basis of IPM (EB-IPM) is the
Natural Methods of Controlling Insect Pests
in an agro or forest ecosystem
This is because increase diversity of natural
enemies decrease the density of the pest
population
As diversity of natural enemy species decreases
Pest population increases

100. Ecological Basis of Pest Management
is an approach to increase and the strengths the natural systems to
reinforce the natural processes of pest regulation
and improve agricultural or forestry production
EBPM in Forestry or Agriculture Crops can be achieved
by applying some
KEY COMPONENTS OF EBPM
(ECOLOGICAL BASIS OF PEST MANAGEMENT)

101. Key components of an EBPM
approach are
1. Selection of pest-resistant, local, native adapted varieties
2. Use of legume-based crop rotations to increase soil nitrate
availability thereby improving soil fertility
3. Use of cover crops, such as green manure to reduce weed
infestation, disease and pest attacks
4. Integration of intercropping and agro-forestry systems
5. Use of crop spacing, intercropping and pruning to create
conditions unfavourable to the pests.
6. Maintaining of soil nutrition and pH levels
7. Applying organic manures to help maintain balanced pH and
nutrient levels.
8. Adding earthworm castings,
9. Using beneficial organisms that behave as parasitoids , predators
and entomo-pathogens

102. Legislative Methods
of Pest
Management
Each of countries in the world and territories has their
own legislation for managing injurious insect pests

Eradication or suppression of the pests
established in a limited area through compulsory
legislation or enactment”.

104. Regulatory Tactics
• Quarantine: limits movement of a pest
• Eradication: must be applied to
relatively small geographic areas
• Suppression: limits pest levels over large
geographic areas

105. Concerns about Legislative strategies
Agronomic risks related to inappropriate use of pesticides
Food safety and other public health risks
(pesticide exposure; pesticide residues)
Environmental risks
(water contamination, biodiversity)
Market access - Pesticide residue requirements are
increasingly important in trade
(Legal requirements and sub- standard qualities)
Pesticide quality - Illegal trade in pesticides (fake products)

106. The goal of Legislative Method of
Insect Pest Control
to prevent the introduction, colonization, and establishment of any
new pests that may cause significant agricultural, environmental
and societal harm in a new area of entry
1. Identify pest harm.
2. Assess pest risk.
3. Manage pest risk.

107. Successful plant pest control depends on the successful
blending of many skills, legislative pest control and
other management strategies which may include:
Identification of risk
Prevention of entry
Survey and detection
Eradication
Retardation of spread
Mitigation of losses
Legislative Tactics/Methods

108. IDENTIFICATION OF RISK
Before prevention strategies are initiated, pest control
agencies must deal it as per the legislative control
tactics to see as to whether:
Is it really a pest ?
Would It be causing significant harm in future ?
Is it likely to be moved artificially into a new area
or already exists in the endangered area
Would It be survived in a new and endangered area

109. PREVENTION OF ENTRY
The primary strategy to exclude pest entry is through the
use of quarantine procedures.
Quarantine inspection programs at various ports of entry
are designed to prevent the introduction and establishment
of insect pests in India
Certain agricultural products are restricted from entry
unless accompanied by documentation to verification or
enter without observing disinfestation techniques
Quarantines are generally not 100% effective for exotic
pests. However, it may reduce the chances of introduction

110. Is a process of isolation in order to prevent the spreading of
infection, caused by any insect pest or disease.
Insect and Plant Quarantine
is a Legal restriction of movement of plant materials between
countries and between states within the country
Different classes of quarantine
Foreign Quarantine
Domestic quarantine
Legislative quarantine
Quarantine

111. Different classes of quarantine
Foreign Quarantine
is a concern with the legislation to prevent the introduction of new pests,
diseases and weeds from foreign countries.
Domestic quarantine
is a concern with the legislation to prevent the movement of plant and animals
from one state to an other in the country
Examples: Banana from Palani hills to prevent Banana Bunchy top Virus (BBTV) spread
Legislative quarantine
is a concern with the legislation to prevent the adulteration and misbranding of
insecticides and to determine the permissible residues in food stuff.
&
To regulate the activities of men engaged in pest control
Examples: Integrated Pest Management, Locust Control and Research, Implementation of Insecticides Act

112. 1. IPM related activities are being implemented through 31
Central Integrated Pest Management Centres (CIPMCs)
established in 28 States and one Union Territory
2. LWO has been implementing locust surveillance system for
monitoring of population of locusts, since its inception in
1939 and controlling desert locust in Scheduled Desert Area
(SDA)
3. Pesticides are regulated under comprehensive legislation,
namely, Insecticides Act, 1968 (the Act) and Insecticides
Rules, 1971 (the Rules).
Examples of legislative quarantine

113. SURVEY AND DETECTION
The local public may not express concern until the pest is
widespread and is causing visible problems.
Survey and detection is also important when the insect pests
penetrate the pest exclusion barrier and get established in a new
locality.
Where previously unknown pests are found, the information must
be reported to the appropriate regulatory agency.
Once an exotic pest is found, additional visual surveys and/or
trapping programs are performed to determine
Several types of surveys and detection trapping programmes can
be conducted to combat with this situation

114. ERADICATION
If prevention is not successful and an re- introduction of the
pest is noticed then the immediate steps are to be taken
eradicate the pest.
Eradication generally means using all available viable options,
which includes:
Application of pesticides.
Elimination of the pest’s food source
Changing the pest’s habitat
Mass trapping
Use of mating disruption techniques
It is important to monitor for the presence of the pest after
the goal of eradication is achieved to assure that the pest has
actually been eliminated

115. RETARDATION OF SPREAD AND MITIGATION OF
LOSSES
If the pest becomes firmly established and eradication is not feasible,
the next practice is to slow or prevent the spread and to mitigate
losses.
Quarantines can be effective at slowing the spread of pests.
Inspections and pest control treatments may help to reduce the
spread.
Treatments to slow the spread of the pest spread and to mitigate
losses in the infested area include:
The use of pesticides
The release of parasites or predators
The release of sterile mates
The removal of the host
The use of varieties that are resistant to the pest

116. LEGAL SCENARIO
(Regulatory requirements in india)
 To safeguard health and safety, Government of India
constituted regulatory requirements for manufacture and
sale of goods and services, including those to be imported
 Regulations are stipulated through Various Acts/ Rules &
Regulations by different Ministries under Government of
India
 Enactment of Acts, Rules & Regulations is done taking
cognizance of the relevant WTO Agreements

117. Following legislative acts have been implemented in
India in different years:
1905 - Federal Insect Pest Act (FIPA) - First Quarantine
act against Sanjose scale
1912 - US Plant Quarantine Act (USPQA)
1914 - Destructive Insects and Pests Act’ of India (DIPA)
1919 - Madras Agricultural Pests and Diseases
Act (MAPDA)
1975 - Implementation of Insecticides Act , 1968
2003 - Plant Quarantine (Regulation of Import into
India)
Pest Legislations Acts in India

118. HIGHLIGHTS OF THE INSECTICIDES
ACT, 1968
An act to regulate the import, manufacture, sale,
transport, distribution and use of insecticides with a
view to prevent risk to Plants/Human beings and for
matters connected therewith.

119. Salient features of the Insecticides Act-1968
1. Compulsory registration with CIB (“Central Insecticides Board”)
2. License for manufacture, formulation and sale at state level
3. Inter departmental/Ministerial/Organizational co-ordination
achieved by high level Advisory Board “Central Insecticides
Board”with 28 members form various fields
4. RC to look after registration aspects of insecticides
5. Enforcement by Insecticide inspectors at state/central level
6. Power to prohibit the import, manufacture and sale of
insecticides and also confiscate stocks. Guilty are punishable

120. Advantages & Disadvantages Biological Control
Advantages
• Low cost
• Has the potential to be
permanent
• Not harmful to non-target
organisms

Survey of affected area: Jodhpur, Nagour, Sikar, Churu & Jhunjhunu
The percentage khejri mortality recorded: 20.93 %
Biotic Causal factors: Ganoderma lucidum (root rot fungus) & Acanthophorus serraticornis (root borer.)
Bioecology of insect: Life-cycle : more than 2 years
pathogenicity test: Koche’s-postulate confirmed , using Ganoderma lucidum
Management trials: Conducted at six experimental sites in five districts viz; Surani (Jodhpur),
Raghunathpura (Nagaur), Jhareli (Nagaur), Goshala (Sikar), Churu (Churu), Sultana (Jhunjhnu).
Biotic & Abiotic factors , responsible for tree mortality

131. plant pathological problems
Initially, a heavily lopped branch on
the top of the tree starts drying and
the disease rapidly progressed from
tip to downward and provides a
favorable medium to the boring
larva of shoot borer.
The affected portions clearly
showed the discoloration and
decaying of tissues. The disease
infection gradually spread over to
the main stem of the tree.

132. Remedial measures for preventing Khejri
mortality
Root treatment + Shoot Treatment + 2/3rd
lopping is proved to be the best remedy for
prevention of Khejri Mortality.
Removal of infected trees from the vicinity
immediately after their exploitation.
A gap of one year in Khejri lopping
Treated Khejri tree in
Farmers field at Jhareli
Shoot treatment of the tree
Root treatment: Bavistine (0.1%)+
Chloropyriphos (0.1%)+ leader or
Agromin ( 2ml/lit) @ 15 lt., aqueous
suspension per tree
Shoot treatment: Copper Carbonate +
Red Lead + linseed 1:1:2 and add
insecticide (Monocrotophos) ( @ 3
ml/Kg) just after lopping during
November-December

136. Other abiotic contributory factors of tree
mortality
Continuous depletion of water tables in western Rajasthan.
Increasing number of tube wells or over exploitation of ground
water.
Effect of low rainfall.
Change in soil properties and agricultural practices are some of
the suspected causes that may play an important role in large-
scale drying of Khejri in western zone of Rajasthan.

INDUCING
PESTS
IN
KHEJRI
(PROSOPIS CINERARIA)

138. Stem galls Eurytoma settitibia
Stem galls are
globose solid hard
and rough swellings
on twigs and
branches.
A mature gall
contains an average
204-223 larval
chambers.
Size and wt. of
mature gall varies
from 20 to 78 mm.
dia., and 28 to 150
mg in wt.
respectively

139. Rachis galls Contarinia prosopidis
Fusiform, solid and
hard galls on the
rachis. Measures as
larger as three
times (6.7mm) of
the dia. of a normal
rachis ( 2.3).
On maturity a
minute circular exit
hole is formed on
the upper surface
to allow the escape
of adult insect.

140. Leaf galls Eriophyes prosopidis
These galls are
hypophyllus,globo
se, solitary,
uniocular with
greenish yellow
colour bodies on
the abaxial and
adaxial surfaces
of leaves.
Area of leaf galls
varies from 0.038
to 0.064 cm2 .
and wt. from 0.48
to 0.75 mg. They
become hard on
maturity.

141. Inflorescence galls Eriophyes prosopidis
These galls are oval,
pyriform, lobed and
branched structures
which represent
with enormous
masses of either
single flower or on
entire inflorescence.
Size and wt., vary
from 4 to 20 mm.,
and 43.1 to 56.7
mg., respectively.
The gall bears
irregular cavities.

142. Parasites of gall formers
Eupelmus species and Tetrasticus spirabilis Waterest are the
chief larval endoparasites of rachis and stem gall inducers of
Khejri.
Both of these parasites have marked characteristics of their
potentiality as being successful natural enemies due to their :
High fecundity
Good synchronization with the host and
A high degree of host specificity.
Therefore, they are considered to be highly promising
biological controlling agents. Biology of these parasites have
been studied.

143. Parasite- predator- pathogen complex of
insect pests of Khejri
Nineteen species of parasites and thirteen species of predators were found
associated with the potential insect pests of P. cineraria, and P. juliflora.
Three species of entompathogenic fungi
namely, Beauveria bassiana,
Metarhyzium sp., Aspergillus parasiticus,
and one species of insect pathogenic
virus, the nuclear polyhedrosis virus
(NPV) were recorded to infect three
species of insect pests of P. cineraria in
arid and semi arid areas.
NPV- Killed larva of babul
defoliator.
BIOLOGICAL CONTROL

144. NPV DISPERSAL AGENT
Adults of a dipterous larval endoparasite, Carcelia
buitenzorgiensis was found to be the most effective
dispersal agents of virus-disease in localized areas
because they feed and developed on virus-diseased larvae
and remain in the larval body from the time when larvae
enter the third instar until the emergence of adult moth.

145. Silvicultural control of gall mite
In lopped trees (once in three years ) of
Khejri, the % of gall formation per
inflorescence was observed minimum (5.6
%) and and pod production was recorded
as high as 13.3%) whereas in unlopped
trees, the % of gall formation was
maximum (49.5%) and resultant pod
production was as minimum as 3.37 %.
The higher production of pods and
lesser formation of galls in lopped trees
was because of the minimum infestation
of gall mite , E. prosopidis.

146. Summary
• An IPM program must be well researched prior to
implementation
• The researcher must have extensive knowledge of the pest as
well as the plants being protected
• Successful IPM programs saves billions of rupees each year in
forestry crops
• Side effects such as environmental and health risks along with
economic costs must be prime considerations when developing
an IPM
• In one way or another, IPM programme are always better than
adopting a single way of insect pest population management.
