微生物源杀虫蛋白的多样性分析

虫害一直是危害农林业最严重的问题之一，给我国第一产业带来极大经济损失。长久以来，使用化学杀虫剂防治虫害已经导致环境污染、昆虫抗性等诸多问题的产生，因此近年来，关于具有广谱、高效、低毒等优点的生物农药的研究与应用不断增加。杀虫蛋白，特别是微生物源杀虫蛋白，作为生物农药的重要分支，因其优秀的杀虫潜力，不断被开发应用。对目前世界范围内已挖掘的微生物源杀虫蛋白信息进行分类介绍及展望，为杀虫蛋白在我国农林等多个行业的应用提供新思路。

Research on the Diversity of Insecticidal Proteins Derived from Microorganisms

Insect problem has been one of the most severe problems in agriculture and forestry, which causes great economic losses to the primary industry in China. For a long time, the use of chemical insecticides for insect control has led to many issues, such as pollution, insect resistance, etc. Therefore, in recent years, the research and application on biological pesticides of broad spectrum, high efficiency and low toxicity is increasing. Insecticidal proteins, especially those of microbial source, as an important branch of biological insecticides, have been continuously developed and applied due to their excellent insecticidal potential. This paper aims to classify the information on insecticidal proteins from microorganism over the world, and to provide fresh opinions for the application of insecticidal proteins in agriculture, forestry and other industries in China.
