Studies on The Interaction of Predatory Insect and Transgenic Raised Prey

ABSTRACT

The objective of this study was to find out the impact of transgenic plant on predators, which forms one of the links in the tritrophic system. The lifestages of D. cingulatus were raised on non- Bt and Bt cotton, and they were fed to the predator R. fuscipes and to find on different key biologicalfactors like stadial periodicity, adult male and female longevity, fecundity, hatching percentage, chronological events of predation, mating and sexratio. Based on the results of the present study the life history of the predator R. fuscipes was unaffected by prey that fed on, or by prey acquiring thetoxin.
