Field experiments were undertaken at the Department of Agril. Entomology, Post Graduate Institute, MPKV, Rahuri, Maharashtra, India to study the bioefficacy of imidacloprid + spirotetramat @ 75+75 g a.i./ha along with certain commonly used insecticides viz., fipronil @ 30 g a.i./ha, dimethoate @ 200 g a.i./ha, lamda-cyhalothrin @ 15 g a.i./ha, profenophos @ 250 g a.i./ha, flonicamide @ 75 g a.i./ha and chlorpyriphos @ 200 g a.i./ha against onion thrips, Thrips tabaci Lindeman, during 2020-21. Study revealed that fipronil @ 200 g a.i./ha was significantly superior over other treatments and was most effective to control thrips population (3.26 thrips/plant). It was followed by dimethoate @ 200 g a.i./ha (5.40 thrips/plant) and profenophos @ 250 g a.i./ha (5.92 thrips/plant).
