飞虱虫疫霉是水稻褐飞虱及其它飞虱、叶蝉的寄生性天敌。在我国南方稻田分布很广,每年9月下旬至11月上旬可造成害虫流行疫病,有的地区寄生率高达70—80％.本文报道该菌的人工培养、菌种保存和杀虫试验。

In southern China rice fields are widely distributed, pest epidemics can be caused from late September to early November each year, and in some areas the parasitism rate is as high as 70-80% .In this paper, the artificial cultivation, strain preservation and insecticidal test of the bacteria were reported.
