Abstract

Compared the effects of the alkaloid nicotine and the flavonoid rutin on the toxicity of B. thuringiensis. Survivorship of M. sexta larvae increased at higher levels of nicotine (0.6, 0.8, 1.0% wet weight), but higher concentrations of rutin did not increase larval survivorship. Experiments on colony growth of B. thuringiensis on nutrient agar containing nicotine or rutin demonstrated that nicotine reduced colony growth to a greater extent. -from Authors
