Management
Hand picking and destruction ofbutterfly eggs and larvae
Spraying with Dipel @ 0.2% orKaranjin @ 2 ml/lit, at 15 daysinterval after 22-25 DAT controlscabbage butterflies and dimond backmoths effectively
Avoid persistent syntheticinsecticides and encourage bioagents like, Hyposoter ebeninus,Cotesia glomeratus, Pb GranulosisVirus (local strain).
In heavy infestation, alternatespraying of Dipel @0.2%, Karanjin@2 ml/lit and endosulfan @0.07%at 15 days interval after 22-25 DATmanage cabbage pests

Major Insect Pests of Solanaceous Crops
Common name Scientific name Nature of damageBrinjal shoot andfruit borer
Leucinodes orbanalis Drying and drooping of shoot and holes onfruit
Brinjal leaf roller Eublemma olivacea Leaf rollingHadda beetle H. vigintioctopunctata
E. dodecastigmaLeaf skeletonisation, browning and drying
Mealy bug Coccidohystrix insolita Yellowing, wilting and drying of leavesTomato fruit borer Helicoverpa armigera Holes on fruitPatato aphid Myzus persicae Yellowing and drying of leaves
Management Regular clipping and burning of
withered dead shoots, leaves and plantresidue reduce further incidence ofSFB, stem borers and mites
Use of lucilure sex pheromone @ 100traps/ha at 20-25 DAT and replacing thelure at monthly interval till the harvestof the crop, effectively controls theSFB.
Application of thuricide dust @ (3x106
spores/ml) and one spraying ofentomopathogenic fungus Verticilliumlecanii Zimn. @ 48x106 spores/mlcontrols epilachna beetles.
Two sprays at fifteen days of intervalwith deltamethrin @ 10-15 g/ha orendosulfan @ 0.15% starting at theonset of the fruits control SFBeffectively.
Use of HaNPV @ 350 LE/ha is highlyeffective against tomato fruit borer
Marigold as a trap crop with tomato ishelpful for attraction of fruit borersfrom main crop and also effectiveagainst root knot nematodes
