Six insecticides were evaluated with Brahmina coriacea (Hope) for their effect on oviposition. Of these chlorantraniliprole was found to be highly effective. The order of toxicity was chlorantraniliprole> bifenthrin> clothianidin> thiamethoxam> chlorpyriphos> imidacloprid. All insecticides at low doses (1.20-0.15x 10-4 g a.i./kg soil) induced reduction in oviposition and it was dose dependent. The number of eggs laid ranged from 28.4-44.8/3 females-maximum reduction being with bifenthrin (82.06%), followed by chlorpyriphos (79.28%).
