Bacillus thuringiensis

(redirected from Bt cotton)

Ba·cil·lus thu·rin·gi·en·sis

a bacterial species that is an insect pathogen used for vector control that has been implicated in human and mammalian infections. In the laboratory it may be misdiagnosed as a strain of Bacillus cereus.

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.
