ABSTRACT
Brinjal (Solanum melongena L.) is a very important crop in Southeast Asia. It is attacked by several insect pests, but brinjal shoot and fruit borer (BSFB), Leucinodes orbonalis G. is the most important insect pest attacking almost all the plant parts except roots. The effect of removal of BSFB infested brinjal shoots and use of light trap was studied for management of this insect pest. The study was conducted on spring sown crop during 2013 in Sahiwal, Pakitan using brinjal variety, Nirala. The experiment was laid out in Randomized Complete Block Design with four treatments each repeated three times. The treatments were T1= removal of infested shoots, T2= Use of light trap, T3= T1+T2 and T4=control. The seedlings were transplanted on April 21, 2013 keeping plant to plant distance of 30cm. Kerosene oil lantern, hung over metallic tray filled with water, was used as light trap. Data for fruit infestation was recorded fortnightly, starting from mid-May, from twenty randomly selected plants. The percent fruit infestation in all three treatments was lower than control except on June 15 when infestation in control and in plots having light traps was not significantly different. Seasonal means for fruit infestation reduced fruit infestation by 16.1, 9.6 and 19.5 percent in T1, T2 and T3, respectively as compared to control.
