Abstract

Cry1Ab and Cry2Aa were overexpressed in Escherichia coli BL21(DE3), and their proportions were determined for evaluating their synergic and antagonistic interactions on Ephestia kuehniella and Plodia interpunctella. Results indicated antagonistic interaction on both lepidopteran pests, and it was concluded that 1:1 combination of Cry1Ab:Cry2Aa should be avoided in control programmes for these larvae.
