日前，一种新型生物杀虫剂由西南农业大学生物技术中心研制成功。该中心利用真菌可以直接侵染昆虫体壁杀死害虫这一特点，开展菌株（高活力和抗逆性）的生产工艺和剂型化工艺，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 Recently, a new type of biocide was successfully developed by Biotechnology Center of Southwest Agricultural University. The center utilizes the fungus to directly infect insect body wall to kill pests, carries out the production process and the formulation process of the strains (high vigor and resistance), and creates the moist microenvironment required for fungal infection through the preparation itself , Reduce the fungal infection host the dependence on the humid environment, which greatly increased
