Abstract

Seasonal incidence and control of insect pests of brinjal with special reference to shoot and fruit borer, Leucinodes orbonalis Guen. in Meghalaya.

Abstract

A survey of the insect pests of eggplant (brinjal) in the Khasi Hills, Meghalaya, India, between 1977 and 1980 showed that the major pest was Leucinodes orbonalis Gn., which damaged between 26.3 and 62.5% of fruits. Other pests included Amrasca biguttula biguttula (Shir.), Henosepilachna vigintioctopunctata (F.) (Epilachna vigintioctopunctata), E. dodecastigma (Wied.), Urentius sp., Euzophera perticella Rag., Autoba olivacea (Wlk.) (Eublemma olivacea), Bemisia tabaci (Gennadius) and Aphis gossypii Glov. L. orbonalis could be controlled by 3 applications of deltamethrin (Decis) at 15 g/ha, 0.15% endosulfan or 0.05% phosphamidon. Of 8 eggplant varieties tested, Pusa purple round was the most susceptible to damage by L. orbonalis, all plants of this variety dying as a result of infestation.
