Bacillus thuringiensis Cry10A-toxin (entomopathogen)

This toxin has been identified in Bacillus thuringiensis var. israelensis and contributes to the toxicity of that variety to mosquitoes. It is also active against other groups of Diptera and has been further shown to be toxic to certain beetles from the group Curculionoidea like the coffee berry borer, Hypothenemus hampei, and the boll weevil, Anthonomus grandis. Attempts are under way to create transgenic plants expressing the toxin with resistant properties against these pests (Nattero et al., 2017).
