Abstract:

The investigation on, “diversity of insect pests and natural enemies in brinjal” was conducted at Horticulture Farm and Department of Entomology, Rajasthan College of Agriculture, Udaipur during kharif 2015. The seedling of brinjal variety “Kavach” was transplanted to record the different insect pests population and natural enemies diversity in the brinjal ecosystem. The diversity of insect pests infesting brinjal during 2015-16 comprised four species of sap sucking insects, the aphids, jassids, whiteflies and tinged bugs; the shoot and fruit borer and hadda beetle .On the basis of mean density, whiteflies had the maximum seasonal mean density 20.11 per 5 plants followed by aphids and jassids. The relative density was also the maximum (25.78) for whiteflies on account of their population abundance. Among the common natural enemies associated with their pests the maximum mean density (15.69) and relative density (42.91) was for the lady bird beetle; however, syrphid fly and spiders were also recorded. Among the major pests infesting brinjal, as per relative density and mean density values for brinjal shoot and fruit borer were (13.49, 10.53), Epilachna beetle (6.15, 4.80), Lace wing bug, (9.05, 7.06) aphid, (22.55, 17.59) jassid (22.98, 17.93) and whitefly were (25.78, 20.11) respectively. The natural enemies relative density and mean density values for Lady bird beetle (42.91, 15.69) Syrphids (29.01, 10.63) and Spiders (28.08, 10.29) respectively.
