西南农业大学生物技术中心日前成功研制出一种新型生物杀虫剂 ,使用这种杀虫剂不会对环境造成污染。该品是利用真菌可以直接侵染昆虫体壁杀死害虫这一特点 ,并通过制剂本身创造真菌侵染所需的潮湿微环境 ,降低真菌侵染寄主对潮湿环境的依赖性 ,从而大大提高杀虫毒力无公害真菌 Southwest Agricultural University Center for Biotechnology recently successfully developed a new type of biological insecticide, the use of such pesticides will not cause environmental pollution. The product is the use of fungi can be directly infected insect body wall to kill pests this feature, and through the preparation itself to create the fungus fungus infection required moist micro-environment and reduce fungal infection host the dependence on humid environment, thus greatly improving the killing Insect toxicity pollution-free fungi
