The present investigation was conducted during kharif season of 2014-15 at Experimental farm of Department of Agriculture Entomology, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, to evaluate the effects of stem smearing treatments against ladybird beetle in cotton ecosystem. Insecticides namely imidacloprid 70 WS, imidacloprid 48 FS, acephate 50 + imidacloprid 1.8 SP, clothianidin 50 WDG used in experiment. However an untreated control was recorded highest population of Ladybird beetles and amongst the treatments, seed treatments with imidacloprid 70 WS at 10 g/kg recorded comparatively higher population of ladybird beetles i.e. 0.47 per plant.This was followed by treatments with acephate 50 + imidacloprid 1.8 SP @ 1:20, clothianidin 50 WDG @ 1:20, clothianidin 50 WDG @ 1:10 and imidacloprid 48 FS @ 1:20. The all treatment insecticides application by stem smearing of and seed treatment is found safer for maintain population of ladybird beetle in cotton ecosystem.
