不同添加物对苏云金芽孢杆菌杀虫活性的增效作用研究进展

苏云金芽孢杆菌（Bacillius thuringiensis，Bt）制剂是当前应用最广、最有效的生物杀虫剂之一，因其对多种昆虫具有特异性杀虫活性，而被广泛用于农林业和公共卫生等领域的害虫防治，但田间施用后，其速效性差、持效期短和防效不稳定等弊端限制了其进一步的推广。将Bt制剂与增效物质（剂）、因子混合使用以提高其杀虫活性和田间防效稳定性，是最快速、有效的途径之一，因而国内外对此开展了广泛而深入的研究。主要介绍了化学添加剂、化学杀虫剂和生物杀虫剂等添加物对Bt制剂杀虫活性的增效作用研究进展，并探讨了增效物质（剂）、因子的开发和应用前景，以期为开发安全、高效的Bt制剂的增效物质（剂）、因子提供一定的参考。

Progress on Synergistic Effects of Various Additives on the Insecticidal Activity of Bacillius thuringiensis

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.
