  1. Israelensis recombinants, which contained recombinants plasmid pmt4 and pmt9 respectively, were obtained by electroporation. the bioassay results showed that the recombinants b - pmt9 and b - pmt4 had toxicities both to resistant and susceptible c. quinqnefasciatus larvae during vegetative growth stage, having the lc ? o values similar to that of. fi. sssii - 1. however, the toxic levels of the final sporulated cultures of recombinants b - pmt4 and b - pmt9 differed, with a lcso value of 2 49mg / ml for b - pmt9 and little toxicity for b - pmt4 by using the plasmid pmt9, m txl gene from b. sphaericus was ligated with p20 and cytjaa gene, giving recombinant plasmid pmpx2
