Efficacy of some insecticides against Eublemma amabilis Moore, a major predator of lac insect, Kerria lacca (Kerr.)

Five insecticides, viz., chlorpyrifos quinalphos, majathion, dichlorvos and endosulfan at different concentrations, were tested for their safety to lac insect, Kerria lacca (Kerr.) and toxicity to different stages of its predator, Eublemma amabilis Moore. Malathion (0.005, 0.01, 0.02%), dichlorvos (0.005, 0.01, 0.02, 0.03, 0.04%) and endosulfan (0.05%) proved to be safer to lav insect. Dichlorvos at 0.03% was found most suitable for the control of egg. larval and pupal stages of the predator.
