dc.description.abstractField experiments were conducted at MARS, Dharwad during kharif 2013-14, to monitor brinjal pests and their natural enemies, mass trapping of moths with water traps and management of shoot and fruit borer with insecticides. The survey in Belagavi and Dharwad districts at vegetative and reproductive stages indicated highest shoot infestation (18.9 %) in vegetative and reproductive stage (10.5 %) in Belagavi. Likewise highest fruit infestation (18.8 %) also more in Belagavi compared to Dharwad district (16.4 %). The sucking pests and natural enemies were more in Belagavi district compared to Dharwad at both the stages. Incidence of BSFB on shoots was highest (34.30 %) during September third week and maximum damage on fruits was during October second week (35.10 %). The incidence of leafhopper was highest at October third week (23.30/ 3 leaves), white fly during first week of November (12.10/ 3 leaves), aphids during first week of November (10.60 / 3 leaves) and mite during third week of November (14.50 / 4 cm2). These sucking pests showed highly significant positive correlation with maximum temperature. The highest activity of coccinellids was observed in first week of November (1.80 /plant), spider during last week of October (1.30 /plant) and chrysopid during October last week (1.30 /plant). The peak moth catch was recorded at September last week (10.7 moths /trap), shoots infestation highest damage was observed during September 4th week (31.6 %) and highest larval population was observed during October last week (4.20 larvae /plant). Among the insecticides evaluated for the management of BSFB cyantranilprole 10% OD @ 0.3 ml/l, rynaxypyr 20 SC @ 0.15 ml, spinosad 45 SC @ 0.1 ml/l registered significantly lowest shoot and fruit damage with higher yield of 198.20, 197.15 and 194.65 q/ha, respectively. Among the insecticides flubendiamide recorded higher B:C ratio (1:5.42).en_US
