Keywords:Okra, jassids, aphids, whiteflies, shoot and fruit borer.
AbstractOkra, Abelmoschus esculentus (L.) Moench is one of the most popular vegetable crops grown in both summer and Kharif seasons in many parts of our country. The crop is ravaged by many species of insect pests. Among the various pests attacking in okra crop leafhopper, Amrasca biguttula biguttula Ishida; aphid, Aphis gossypii Glover; whitefly, Bemisia tabaci Genn.; and shoot and fruit borer, Earias vitella Fab. are considered as major pests and cause appreciable losses in yield. The use of chemicals forms an important part of pest management strategies. Due to variation in the agro-climatic conditions of different regions, insects show varying trends in their incidence and extent of damage to the crop. The present review highlights the seasonal incidence, correlation studies with weather parameters and critically review the literature generated on the evaluation of different insecticides for the management of insect pests infesting okra crops at different locations in India and abroad.
