    摘要: Disclosed and claimed are toxins and genes from Bacillus thuringiensis strains designated PS80JJ1, PS158D5, PS167P, PS169E, PS177F1, PS177G, PS204G4, PS204G6 which can be used to control corn rootworm. Mutants which retain the activity of the parent strain can be used to control the pest. Further, isolated spores or purified toxins from these isolates can be used to control corn rootworm. Genes encoding .delta.-endotoxins can be removed from these strains using standard well-known techniques, and transferred to other hosts. Expression of the .delta.-endotoxin in such hosts results in control of corn rootworm larvae.
