Natural enemies of insect pests of cotton in Orissa

摘要

Survey for natural enemies of major insect pests of cotton (cv. MCU-5) around Umerkote, Orissa resulted in recording six species of parasitoids, eight species of predators and two species of pathogens. The larval parasitoids viz., Rogadinae sp. and Mesochorus sp. are new records on Earias vittella Fabricius and Syllepte derogata Fabricius, respectively. Maximum activity of the natural enemies was recorded during September-November synchronizing with the peak occurrence of the pests.
