Transgenic cotton showing resistance against target insects pests was found successful in Pakistan. It showed more resistance against lepidopteran insects pests. In this research we conducted field experiments in which sucking insect pests including white flies, thips, jassids, aphids were observed for population dynamics in Bt cotton as compared to non-Bt cotton. Transgenic cotton varieties included FH- Lalazar, FH- 142, FH- 118 were used as compared to NIAB- 2008 as non-Bt cotton. Sampling method used in this research was a plastic bag method in which three different leaves were collected from the same plant. And different samples were collected in Bt cotton as compared to non-Bt cotton fields. Results showed that no difference was found in population dynamics of white flies, thrips, jassids and aphids. Although some numerical differences were found in its population dynamics and densities but non significant difference was observed in Bt cotton as compared to non-Bt cotton. Results showed that Bt cotton not showing any ecological issue regarding non-target pests in Bt cotton ecosystem.
