Bacillus thuringiensis Cry1B-toxin (entomopathogen)
This toxin is mainly active against caterpillars of various lepidopteran species, including pests like Plutella xylostella or Spodoptera species. Several non-target species have been also shown to be affected. It is commercially available as crystal formulation and has been used in genetically modified crops. However, pests can develop resistance to the toxin (e.g. see Wang et al., 2007). Several forms of the toxin have been described.
