S. Naimov et al., Bacillus thuringiensis delta-endotoxin Cry1 hybrid proteins with increasedactivity against the Colorado potato beetle, APPL ENVIR, 67(11), 2001, pp. 5328-5330
Cry1 delta-endotoxins of Bacillus thuringiensis are generally active agains
t lepidopteran insects, but Cry1Ba and Cry1Ia have additional, though low,
levels of activity against coleopterans such as the Colorado potato beetle.
Here we report the construction of Cty1Ba/Cry1Ia hybrid toxins which have
increased activities against this insect species.
