Abstract

Insecticides were evaluated to determine their ovicidal activity against rice feeding planthoppes, Nilaparvata lugens (Stål) and Sogatella furcifera Horvath. Carbofuran, methyl parathion, and triazophos were ovicidal as foliar sprays and carbofuran, diazinon, metalkamate, and triazophos were ovicidal as paddy-water applications of granules in insectary Studies. In a field study, only triazophos as a foliar spray provided significant ovicidal activity against N. lugens. Eggs of S. furcifera were more susceptible to insecticides than N. lugens. Ovicidal activity was dependent on age of egg at the time of insecticide application and on insecticide concentration.
