Abstract

Research progresses in the control of Colorado potato beetle Leptinotarsa decemlineata (Say) using the Bacillus thuringiensis.

Abstract

Colorado potato beetle Leptinotarsa decemlineata (Say) is an important invasive pest and poses a threat to the production of potato in China. Bacillus thuringiensis is a kind of biocontrol bacteria for the agricultural pests and effective in the control of the Colorado potato beetle. This article reviewed the progresses and applications of B. thuringiensis in the control of Colorado potato beetle, including the invasion of Colorado potato beetle, the structure and insecticidal mechanism of the crystal toxins of B. thuringiensis, the Bt toxins active to Colorado potato beetle, the toxic mechanism of Bt crystal proteins on the Colorado potato beetle and the resistance mechanism of Colorado potato beetle to Bt toxins. It was prospected that the Colorado potato beetle could be controlled through conducting Bt research in terms of new gene mining and insecticidal mechanisms.
