摘要

A susceptible laboratory strain of cotton bollworm, Helicoverpa zea, was established from a Monsanto laboratory colony. The baseline susceptibility of this strain to MVP II and Cry1Ac toxin was 24 μg/g and 9μg/g diet, respectively. Subsequently, twoCry1Ac-resistant strains of cotton bollworm were selected using MVP II (MR) or activated Cry1Ac toxin (AR). Larvae that molted into second instar within seven days of selection were reared until pupation on regular diet (containing no Cry1Ac). Current resistant ratios for MR and AR strains are 12.6 and 35.9 fold after seven generations of selection, respectively. Selection studies indicated approximately three times quicker resistance development in the AR compared to the MR strain. Additionally, there were higher fitness costs in terms of fertility and fecundity in the MR compared to the AR strain.
