The toxicity of Bacillus thuringiensis Cyt1Aa protein to sheep blowfly larvae depends on its solubilization and proteolytic activation. Cyt1Aa crystals were not toxic. Full-length and trypsin-digested Cyt1Aa proteins were toxic to larvae of three species of sheep blowfly. Neither full-length nor trypsin-digested Cyt2A soluble crystal proteins were toxic.
