dc.description.abstractThe investigation on “Diversity and Management of Sucking Insect pests of brinjal” was carried out at the Horticulture Farm, Rajasthan College of Agriculture, Udaipur (Rajasthan) with the objectives of:- i. To study the influence of abiotic environmental factors on the incidence of sucking insect pests of brinjal. ii. To establish the diversity of insect pests and natural enemies in brinjal. iii. To evaluate the relative efficacy of newer insecticides against sucking insect pests of brinjal. The major sap sucking insect pests including aphid commenced in the last week of September and attained its peak during third week of October (43rd SMW). Jassid commenced in the last week of September and attained its peak during last week of October (44rd SMW) and whiteflies in the last week of September attained its peak during last week of October (44rd SMW). The pests showed a positive significant correlation with temperature and negative and with humidity. 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. On the basis of first and second sprays overall efficacy of pesticidal treatments at, three, five and seven, days after each spray against aphid, jassid and whitefly revealed that imidacloprid 0.5 ml /lit as most effective The treatment of azadiractin 3000 ppm proved least effective followed by NSKE (5.0%). The fruit yield was maximum (28.69 kg /plot) in the treatment of imidacloprid. The fruit yield drastically reduced in untreated check plots (15.90 kg /plot).en_US
