Abstract

The brinjal shoot and fruit borer, Leucinodes orbonalis is a destructive pest of brinjal and its control is difficult as the larvae inhabited inside the shoots or fruits of brinjal. Two different studies were conducted in farmer’s field at Coimbatore, Tamil Nadu, India during Rabi 2013/14 (September, 2013 – January, 2014) and 2014/15 (September, 2014 – January, 2015) to evaluate the efficacy of 1) types of traps viz., sleeve and Wota-T traps, and erection heights viz., 30, 60, 90 cm above the crop canopy and at crop canopy level, and 2) concentration of lure viz., one, two and three mg (Lucin-lure®), and frequency of replacement of lure viz., 21, 45 and 60 days. The results showed that the Wota-T traps baited with 3 mg lure concentration, replaced at every 21 days caught more number of male moths of L. orbonalis. Trap catch was significantly higher in pheromone traps placed in the same level of canopy.
