This document discusses 8 major pests that affect brinjal crops: 1. Brinjal fruit and shoot borer caterpillars bore into and feed on growing shoots, leaves, and fruits, damaging the plant. 2. Epilachna beetles and their grubs eat chlorophyll from brinjal leaves, creating skeletonized patches. 3. Brown leaf hoppers suck plant juices and transmit diseases, stunting plant growth. 4. Whiteflies suck plant juices and excrete honeydew, promoting sooty mold that reduces photosynthesis. 5. Aphids suck plant juices, deforming and drying leaves. 6. Brinjal lace bugs suck plant juices, causing

small black dots on the pronotum and elytra.

creamy yellow white, when full grown.

and is covered with spiny structures all over.

15. Epilachna
Beetle

16. Life history
• Eggs are laid generally on the under surface of
leaves.
• Larval period lasts for 10-35 days
• Pupation takes place on the leaf surface.
• The pupal period varies from 3-6 days
• Total life cycle takes 17 to 50 days.

17. Life stages

18. Nature Of Damage
•Both the grub and
beetle eat the
chlorophyll of the leaf
in between the veins
and cause
Skeletonized patches
on leaves.

19. Control Measures
•Hand picking will prove effective as the beetles are sluggish
during the morning hours.
•If the area is small, collection and destroying the egg masses
which can be spotted easily.
•Egg parasitoid- Tetrastichus ovularum, larval parasitoid - Uga
menoni suppress the population during March – July
•Foliar spray with DDVP 1 ml/l in nursery as well as planted crop
or carbaryl 3 g/l or profenofos 2ml/l or quinalphos 2 ml/l.

20. 3. Brown leaf hopper
•S.N. - Cestius phycitis
•Family - Cidadellidae
•Order - Hemiptera

21. Mark of identification
•Adult
• Small light brown leaf hopper

22. Nature Of Damage
• Reduction in size of leaves
• Shortened petioles
• Excessive growth of branches general stunting of
plants
• Conversion of floral parts into leafy structures
• Plants become bushy
• Fruiting is rare
• Vector of little leaf of brinjal

23. Little leaf of Brinjal

24. Control measure
•Remove infected plants and destroy
them
•Before transplantation dip the seedlings
in 0.2% carbofuran 50 STD solution
(control insect vectors)
•Spray with dimethoate 0.3%
