摘　　要：植物寄生线虫(Plant parasitic nematodes)对农林业生产造成了巨大的经济损失,为减少环境污染,发展绿色农业,生物防治愈发受到关注。Bt菌(Bacillus thuringiensis, Bt)作为一种重要的生防细菌,对鳞翅目、鞘翅目、双翅目和线虫具有特异性的杀虫活性,对人类和非靶标昆虫无害。文章对已报道的Bt菌及其杀植物线虫Cry蛋白种类、结构特征和杀虫机制等方面研究进展进行了简要综述。Plant parasitic nematodes have caused huge economic losses to agricultural and forestry production.In order to reduce environmental pollution and construct green agriculture,biological control has attracted increasing attention.Bacil⁃lus thuringiensis(Bt),as a vital biocontrol bacterium,has been proved to have specific insecticidal activity against lepidop⁃tera,coleoptera,diptera and nematodes,and is harmless to human and non-target insects.In this paper,we briefly reviewed the research progress of Cry protein of Bt bacteria and its Cry protein species,structural characteristics and insecticidal.
