Seven modified recombinant insecticidal Cry3Aa toxins were prepared. Tenebrio molitor larvae were exposed to different Cry3Aa toxin derivates in a wide concentration range. For two Cry3Aa derivatives statistically significant lethal and sublethal effects were documented. Bioassays performed with Tribolium castaneum over the entire larval stage confirmed that this species is highly insensitive to Cry3Aa. Leptinotarsa decemlineata was included in our list of tested species. Leaf disk bioassay procedure has been developed and will be used for comparison of relative efficiency of the modified recombinant Cry3Aa derivates.
