Abstract

Susceptibility of three biological control agents of Brinjal insect pests to seven selected insecticides were evaluated. Lowest mortality (6.67 %) of Camponotus compressus was found in Bactoil and Nimbicidene 0.03 EC treated brinjal and the highest mortality (100%) was recorded from Necstar-50 EC and Booster-10 EC treatments. The lowest mortality of Micraspis crocera Muls was recorded from Bactoil (3.67%) treatment while the highest mortality of Micraspis crocera Muls was found in Necstar-50 EC (100.00%) and Booster-10 EC (100.00%) treated brinjal. In case of Trathala emergence from infested shoot, the highest percentage (22.22%) was observed in the untreated control plots and lowest emergence was in Necstar-50 EC (2.22%) and Proclaim-5 SG (3.33%) treated brinjal shoots. In case of the infested fruit specimen, the highest (22.22%). Trathala emergence was found in the untreated control plots followed by the plots treated with Bactoil (18.89 %) and Nimbicidene 0.03 EC (17.78 %) while the lowest was in Necstar-50 EC (1.11%) and Booster-10 EC (2.22 %) treated brinjal fruits. Compatibility factor was highest for Bactoil (13.94, 25.33 and 27.92 with C. compressus, M. crocera and Trathala, respectively) and was lowest for Booster-10 EC (0.86, 0.86 and 4.30 with C. compressus, M. crocera and Trathala, respectively). Therefore Bactoil, Nimbicidene 0.03 EC and Tracer-45 SC were found to be the most compatible insecticides for controlling the Brinjal shoot and fruit boruss.
