Study on Insect Pest Succession of Brinjal Crop Ecosystem in Western Region of Uttar Pradesh, India

Abstract

The present investigation was carried out during Kharif, 2011 at Crop Research Centre (CRC) of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U.P.). During the studies on the insect-pests succession revealed that a total of eight insect species were found associated with brinjal crop at different crop growth stages. The first attack on the crop appeared in the one week after transplantation and continued up to till crop harvested. pests were found attacking on the crop were jassids (Amrasca biguttula biguttula), aphids (Aphis gossypii), white fly (Bemisia tabaci), leaf roller (Eublemma olivacae), shoot and fruit borer (Leucinodes orbonalis), epilachna beetle (Epilachna vigintioctopunctata), leaf webber (Psara bipunctalis) and grass hopper (Chrotogonus spp.). Among them, brinjal shoot and fruit borer (L. orbonalis) was recorded as major pest. Jassids (A. biguttula biguttula Ishida), aphid (A. gossypii Glov.) and epilachna beetle (E. viginitioctopunctata F.) were found to damage the crop moderately. Other insects pests recorded on the crop were of less importance and extent of damage caused by them was found without much economic loss.
