Effect of treatment of broodlac with a few insecticides on the harboured inimical insects

The effect of different concentrations of ethofenprox, endosulfan, and profenfos on the lac insect predator, Eublemma amabilis Moore and two important parasitoids Aprostocetus purpureus (Cam.) and Tachardiaephagus tachardiae (How.) was evaluated by dipping mode. Profenfos was found to be toxic to lac insect. Population of E. amabilis was suppressed by endosulfan while none of the insecticides were able to suppress the population of the parasitoids A. purpureus and T. tachardiae.
