abstract：:Twelve Cry1 and two Cry9 delta-endotoxins from Bacillus thuringiensis were tested for their activity against black cutworm ( Agrotis ipsilon). A. ipsilon was not susceptible to many toxins, but three toxins had significant activity. Cry9Ca was the most toxic, followed by Cry1Aa and Cry1Fb. Hybrids between these three ...
