Bacillus thuringiensis(Bt) an entomopathogenic BACILLUS species that produces a TOXIN called delta (8) endotoxin, which kills insect larvae. The organism is used as a microbial INSECTICIDE for the BIOLOGICAL CONTROL of various LEPIDOPTERA. Genes for the toxin have been transferred to plants by GENETIC ENGINEERING techniques to make them insect-tolerant. See also BIOPESTICIDE.
