Recombinant Cry3Aa has insecticidal activity against the Andean potato weevil, Premnotrypes vorax



Recombinant Cry3Aa has insecticidal activity against the Andean potato weevil, Premnotrypes vorax



Biochemical and Biophysical Research Communications 279(2): 653-656



This paper reports the cloning and recombinant expression of Cry3Aa from Bacillus thuringiensis var. san diego, and demonstrate the toxicity of Cry3Aa to the Andean potato weevil P. vorax. In toxicity tests, a nonspecific mortality of ~15% was observed when the first instar larvae of P. vorax were exposed for 5 days to media whose surface was spread with purified native or recombinant toxins at 70 micro g/ml.
