Transgenic plants expressing insecticidal proteins from the Bacillus thuringiensis (Bt) have provided an effective way to control target pests. However, the toxicity of Bt proteins against yellow peach moth (YPM), Conogethes punctiferalis (Guenée), one of the most serious maize pests in China, has not received much study. Therefore, we performed diet-overlay bioassays to evaluate the insecticidal activities of Cry1Ab, Cry1Ac, Cry1Fa, Cry1Ah, Cry1Ie, Cry2Aa, and Vip3Aa19, as well as the interaction between Cry1-Class, Cry2Aa, and Vip3Aa19 against YPM.
