Resumo: We characterized a novel Bacillus thuringiensis isolate native to China (HS18-1) that shows a spherical crystal harboring two major proteins of about 70 and 130kDa, and contains three novel cry genes (cry4Cb1, cry30Ga1, cry54-type). Furthermore, the cry4Cb1 and cry30Ga1 genes were expressed in Escherichia coli BL21 (DE3): pLysS. Insecticidal activity tests showed that the cry4Cb1 protein exhibited larvicidal activity against Aedes aegypti (Diptera) and the cry30Ga1 protein was toxic to both A. aegypti and P. xylostella (Lepidoptera).
