| Abstract: | Mixtures of the final whole cultures of recombinant strains Bt B601, Bt B611, Bt B640, Bt U 30(expressing Cry4Aa, Cry4Ba, Cry11Aa and Cyt1Aa protein of Bacillus thurigiensis subsp. israelensis respectively) and Bt CW 3(expressing the Binary toxin of Bacillus sphaericus ) were used in bioassays against resistant Cpq larvae to value the synergism among the mosquito larvicidal toxins. Synergy was clearly evidenced. In particular, there were synergistic interactions between Binary toxin and Cry4Aa, between binary toxin and Cry4Ba, Cry4Aa and Cry4Ba, Cry4Aa and Cry11Aa, and between Cyt1Aa and Cry4Aa. |
