Abstract: As one of the most widely used and the most effective biopesticides, Bacillius thuringiensis (Bt) preparations are widely employed for pest control in the fields of agriculture, forestry and public health because of the specific insecticidal activity. However, after field application, the further popularization of Bt preparations has been limited due to the disadvantages, such as poor readily availability, short-duration action and unstable control effect. It is the most fast and efficient way by mixing Bt preparations with all sorts of synergistic agents and synergistic factors to improve the insecticidal activity and field control effect stability. Extensive and in-depth researches on synergistic effects of various additives on Bt preparation have been carried out at home and abroad. In this paper, the progress on synergistic effects of chemical additives, chemical insecticides and biopesticides on Bt preparations were reviewed, and the development and application prospects of synergistic agents and synergistic factors were also discussed in order to provide references for developing safe and efficient synergistic agents and synergistic factors of Bt preparations.

Key words: Bacillius thuringiensis, additives, insecticidal activity, synergistic effect
