Abstract

The glabrous varieties of cotton favoured higher parasite activity on whitefly, recording more than 40 percent parasitisation, while hairy varieties recorded higher number of predatory mites. The integrated management programme involving natural insecticides of plant and animal origin was significantly superior in conserving the parasite and predatory populations compared to the existing (bollworm based) schedule as well 858 schedule involving some new and highly effective insecticides.
