我国研究应用病原微生物防治害虫,其中白僵菌(Beauveria bassiana)是最多最广泛的一个病原真菌。据统计全国白僵菌的年产量达3,000t 以上,防治面积高的年分达2,000万亩,防治对象有60多种,其中主要对象在林业上是松毛虫(Dendrolimus spp.)、松毒蛾(Dasydira sp.)、木麻黄毒蛾(Lymantria xylina):农业上主要是玉米螟(Astrinia sp.)。防治效果在80%以上。我国系统的开展白僵菌防治害虫的研 In China, pathogenic microorganisms are used to control pests. Beauveria bassiana is one of the most extensive and widespread pathogenic fungi. According to the statistics, the annual output of Beauveria bassiana reaches over 3,000 tons, the annual control area is up to 2,000 million mu and there are over 60 kinds of control objects. Among them, Dendrolimus spp. Dasydira sp., Lymantria xylina: Agriculturally mainly Astrinia sp. Control effect in more than 80%. Research on pest control of Beauveria bassiana system in our country
