EFFICACY OF INSECTICIDES AGAINST FRUIT BORER, HELICOVERPA ARMIGERA(HUBNER) ON TOMATO

摘要

The important insect pests of tomato are fruit borer, Helicoverpa armigera (Hubner); whitefly, Bemisia tabaci Gen; jassids, Amrasca devastans Ishida; leaf miner, Liriomyza trifolii (Blanchard); potato aphid, Myzus persicae (Thomas); and hadda beetle,Epilachana dedecastigma Widemann of these fruit borer is the most important as a caterpillar may feed on a single fruit or move from fruit to fruit, thus damaging several fruits. There is a need to search for newer chemicals that are selective, less persistent and eco-friendly and hence the present study.
