INTRODUCTION
Invasive pests are non-native or exotic
organisms that occur outside their natural
adapted habitat and dispersal potential.

which becomes established in

Chilo partellus and C.
orichalcociliellus were nearly equally
abundant in maize and sorghum, and
that Sesamia calamistis was much less
common.

Risk assessment review
Monitoring
• There is need to study the biology and ecology of known
insect pests and their natural enemies.
• Study the ecology and genetic makeup of the Invasive insect
pest.
• Tracking of geographical distribution of pest.
• Developing cultivars resistant to insect pests.
MANAGEMENT STRATEGIES AGAINST INVASIVE
INSECT PESTS
• Judicious use of insecticides to prevent resistance and
resurgence development.
• To identify, conserve and augment natural enemies of invaded
insect pests.
• Modify crop management practices.
• Develop suitable integrated pest management programmes.
• Phytosanitary regulations to prevent or limit the introduction
of risky insect pests.

Main Host: Papaya
• A white wax and flour-like substance around the body is
the reason for not able to control this pest easily.
• Spread rapidly due to lack of natural enemies.
• Reproduction is 15 times a year and capable of laying (500
and 600 eggs a year).

important plants such as papaya, citrus, yams, cassava, hibiscus,
and several other unconfirmed hosts.
Initial reports from Tamil Nadu, India, were on papaya, but it was
recently found to be attacking cotton for the first time in Coimbatore,
Tamil Nadu
Severe infestation (80 to 90 %) was observed on the crops viz.,
papaya, mulberry, tapioca, brinjal, tomato, bhendi and flower crops.

The main host of T. absoluta is tomato, but potato is also reported
as a host together with Lycopersicon hirsutum, Solanum lyratum
and various wild solanaceous species such as Solanum nigrum,
Solanum elaeagnifolium, Solanum puberulum, Datura stramoniu,
Datura ferox and Nicotiana glauca.
(Galarza, 1984; Notz, 1992)
Description
• Eggs are cylindrical and creamy white in colour and are laid
singly or in small groups (4 to 8 days).
• Larva - four instars.
• Neonate larva mines the leaf, stem or fruit. Incubation period
is around seven days.
• Pupation may take place in the soil, on the leaf surface, within
mines, in cocoons.
• Adult is greyish brown in colour and is 6-8 mm long.
• Adults live for about 7-9 days at 24-260C, and for about 23
days at 130C.
• Larvae mine in the mesophyll of leaves and
make irregular, papery mines.
• The larvae also mine apical buds and stems.
• In cases of heavy infestation, both green and
red fruits are attacked and infested fruits show
small holes on the surface and the larvae
tunnel / mine below the surface.
DAMAGE SYMPTOMS
Combine application of mass release of Trichogramma pertiosum and
Bacillus thuringiensis resulted fruit damage only 2 % in South America.

Nesidiocoris tenuis Reuter
The most widely spread species are mirids belonging to the tribe Dicyphini, with
Nesidiocoris tenuis (Reuter) spontaneously recorded in eleven countries almost all
year round both in protected and open-field tomato crops.
Predators
Integrated Pest Management Strategy
• Massive trapping before planting,
• Clearing the soil of crop residues,
• The application of imidacloprid in the irrigation water 8- 10 days
after planting,
• The application of either spinosad or Indoxacarb if occasional
individuals of Tuta absoluta are observed.
• Elimination of the remnants of the crop immediately after the last
fruits have been harvested

Male Female
Main Host: Capsicums
and cucumbers
Host
It causes direct damage by feeding on a variety of hosts
including groundnut, cotton, tobacco, vegetables (cucurbits,
cabbage, eggplant, tomato, carrot, peas, beans, capsicum,
etc.), fruits (grapes, apple, peach, plum, etc.) and ornamentals
(gladiolus, hibiscus, geranium, roses, orchids, etc.).
• Capsicums and cucumbers that have been attacked
whilst young, show serious distortions as they mature.
• Eggs laid in petal tissue cause a 'pimpling' effect in
flowers such as orchids.
• Egg laying on sensitive fruits such as table grapes,
tomatoes and apples leads to the spotting of the skin of
the fruit, which reduces the aesthetic value of the fruit. It
can also lead to splitting and subsequent entry of fungi.
DAMAGE SYMPTOMS
Vector for viral disease
• Tomato spotted wilt virus (TSWV),
• Impatiens necrotic spot virus (INSV),
• Groundnut ringspot virus (GRSV),
• Chrysanthemum stem necrosis virus (CSNV) and
• Tomato chlorotic spot virus (TCSV).
(Whitfield et al., 2005)
• Hymenopterous parasites has been less effective, although the
polyphagous eulophid, Ceranisus menes, has been used in several
countries with varying levels of success.
• Fungal pathogens and nematodes, such as Beauveria
bassiana and Steinernema feltiae, are also being commercially used.

MANAGEMENT
Central Plantation Crop Research Institute (CPCRI), Kasargod, has
recommended the following measures:
• Spraying starch solution (1%) to dislodge the heavy sooty mould
deposition on the leaves of infested plants.
• Use of yellow sticky traps to trap the adult whiteflies.
• In case of severe infestation, spray neem oil 0.5%.
• Encarsia guadeloupae Viggiani (Aphelinidae: Hymenoptera)
• Encarsia dispersa Polaszek parasitisation ranging from 40 to 70%.

The pest is found to be colonising on coconut palm, Cocos
nucifera (Arecales: Arecaceae) and ornamental palm, Dypsea
lutescens (Arecales: Arecaceae) at Mandya and Mysore districts of
Karnataka during February, 2019.
• Eggs and larvae occur on the underside of palm fronds, and when abundant
they are highly conspicuous due to the dense flocculent white wax which
covers the black pupae.
• Eggs are stalked, initially creamy white and turn to dark brown before
hatching.
• The first instar nymph has four pairs of wax plumes excreted by glands at
the base of dorsal setae.
• Adults are different from the other recently invaded whiteflies of coconut;
smaller than rugose spiralling whitefly, Aleurodicus rugioperculatus and
larger than Bondar's nesting whitefly, Paraleyrodes bondari, without any
wavy marking on the wings.

NATURAL ENEMIES
Encarsia spp.
(Hymenoptera: Aphelinidae)
Dichochrysa astour
(Neuroptera: Chrysopidae)
Cybochephalus spp.
(Coleoptera: Nitidulidae)
Chilocorus nigrita and Jauravia pallidula
(Coleoptera: Coccinellidae)
CONCLUSION
• Invasion of insects was the result of globalization and the
invasive insect pest caused substantial damage to the native flora
and fauna, and also resulted in the extinction of species.
• These species, if not accompanied by the natural enemies which
keep them in check in their native range, can multiply in large
proportion and cause damage to economically important plant
species and crop plants.
• Hence it is necessary to know the recent invasive insect pests in
order to protect the crops from economic loss.

    Distributed widely inthe tropics and subtropics and colonize on more than 110 plant species belonging to Arecaceae, Rutaceae, Solanacee, Cycadaceae and Lauraceae. DISTRIBUTION (Malumphy, 2013) It is now found in Africa, North and South America, Central America and the Caribbean, Europe and Oceania.

    HOST The pest isfound to be colonising on coconut palm, Cocos nucifera (Arecales: Arecaceae) and ornamental palm, Dypsea lutescens (Arecales: Arecaceae) at Mandya and Mysore districts of Karnataka during February, 2019.

    • Eggs andlarvae occur on the underside of palm fronds, and when abundant they are highly conspicuous due to the dense flocculent white wax which covers the black pupae. • Eggs are stalked, initially creamy white and turn to dark brown before hatching. • The first instar nymph has four pairs of wax plumes excreted by glands at the base of dorsal setae. • Adults are different from the other recently invaded whiteflies of coconut; smaller than rugose spiralling whitefly, Aleurodicus rugioperculatus and larger than Bondar's nesting whitefly, Paraleyrodes bondari, without any wavy marking on the wings.

    CONCLUSION • Invasion ofinsects was the result of globalization and the invasive insect pest caused substantial damage to the native flora and fauna, and also resulted in the extinction of species. • These species, if not accompanied by the natural enemies which keep them in check in their native range, can multiply in large proportion and cause damage to economically important plant species and crop plants. • Hence it is necessary to know the recent invasive insect pests in order to protect the crops from economic loss.
