自陕西省安康县采到的栎尺蠖感病虫尸上分离到一株病原真菌,经室内生物学测定为簇孢霉属一新种——安康簇孢霉,其致死中量LD_(50)为3.1776×10~9孢子/mg虫体,用3亿孢子/ml悬液与5000倍敌百虫混合防治栎尺蠖,死亡率达83.1%。
A strain of pathogenic fungi was isolated from the oak scale moth in Ankang County, Shaanxi Province. The indoor test showed that the strain LD50 (50) For 3.1776 × 10 ~ 9 spores / mg worms, with 300 million spores / ml suspension and 5000 times the mixture of trichlorfon control Quercus mongolica, the mortality rate of 83.1%.
