根据5种不同粉拟青霉菌株的产孢量及对春尺蠖致病力的研究结果，筛选出虫体菌株为优势菌株，人工培养的菌株尽管产孢量较高，但致病力却降低了。
According to the sporulation of five different strains of Paecilomyces tenuis and the virulence of Paecilomyces tenuipes, the strains of parasites were selected as the dominant strains. Although the sporulation of cultivated strains was higher, the virulence of the cultivated strains was lower It’s
