Abstract

One preliminary and two large scale field experiments were conducted to study the effect of Cypermethrin 25EC (0.05%) and Neem Seed Kernel Extract (NSKE 4%) on the attraction of brinjal shoot and fruit borer (BSFB), Leucinodes orbonalis Guen. to synthetic sex pheromone. Results indicated reduced catches in cypermethrin sprayed plots (0.04 ± 0.11 and 0.06 ± 0.05 males/trap/night in I and II large scale experiments, respectively). Significantly more male BSFB moths were trapped in control [0.20 ± 0.31 (I large scale trial) and 0.16 ± 0.09 males/trap/night (II large scale trial)] and NSKE [0.10 ± 0.16 (I large scale trial) and 0.14 ± 0.11 males/trap/night (II large scale trial)] treated plots. Per cent borer incidence in NSKE and cypermethrin treated plots were on par.
