Abstract: In order to solve the problems existing in the application of Bacillius thuringiensis (Bt) preparations, such as poor readily availability, short duration action, unstable control effect and emerging drug resistance, various additives have been widely used in Bt biopesticide and achieved the synergistic effect on pests control. In this paper, the studies on synergistic mechanism and action pathways of various additives on Bacillus thuringiensis at home and abroad were reviewed, and the potential and means of their actions were also pointed out, which was expected to provide references for investigating the insecticidal mechanisms of Bacillus thuringiensis.

Key words: Bacillius thuringiensis, insecticidal activity, synergistic mechanism
