对在广东省昆虫病原真菌资源调查中发现的一种经常在褐飞虱种群中引发流行病的昆虫病原真菌进行了研究。经鉴定,该菌为飞虱虫疠霉(Pandora delphacis),并就其感染飞虱后对褐飞虱主要生化指标的影响以及该菌初生分生孢子萌发率进行了测定。为开发利用该菌防治褐飞虱提供科学依据。
An insect pathogenic fungus frequently found in the populations of BPN in the survey of insect pathogenic fungi in Guangdong Province was studied. The strain was identified as Pandora delphacis, and the main biochemical parameters of the brown planthopper (BPH) infection and the germination rate of primary conidia of the strain were determined. For the development and utilization of the bacteria to provide the scientific basis for the prevention and treatment of brown planthopper.
