The present investigations were undertaken on laboratory studies of Trichogramma japonicum (Ashmead) during the year 2013-2014 in the Bio-control laboratory, Department of Agricultural Entomology, College of Agriculture, Dapoli (Maharashtra). The results of effect of different insecticides on adult emergence of T. japonicum revealed that insecticides viz.,oxydemeton methyl and cypermethrin can be safely used in the field after release of T. japonicum. However, insecticides viz.,dimethoate, indoxacarb and emamectin benzoate can wisely used in the field 4-5 days after release of T. japonicum, while use of malathion and dichlorvos should strictly be avoided.
