ABSTRACT
A field experiment was conducted at Experimental Farm, Department of Agricultural Entomology, College of Agriculture, MAU, Parbhani, during the year 2009-2010 to study the effect of stem application of insecticides on the population of natural enemies of cotton. The stem application of clothianidin 50% WDG @ 1:30 dilution proved safer treatment than all other insecticidal treatments against Chrysopa predator at 3, 7, 14 days after treatment apllication and on the basis of overall efficacy, followed by acephate, acetamiprid, fipronil, thiamethoxam and imidacloprid. The stem application of clothianidin was significantly safer to ladybird beetle predator, followed by dimethoate, acetamiprid and thiamethoxam.
Key words :
Acephate, Chrysopa, Clothianidin, Coccinellid beetle, Cotton seed yield, Imidacloprid, Stem application.
