1984～1986年根据“Koch”法则对军绿绿僵菌(Metarhizium iadini)的原寄主梨虎(Khynchites Coreanus Kono)进行多次室内、田间人工接种试验结果表明:室内成虫感病致死率89.3～100％,对照死亡率0～5.9％,幼虫感病致死率66.1～100％,对照死亡率为0。贵州省植物园田间防治,成虫感病致死率33～66.7％,校正死亡率53.3％,对照自然死亡率12.5％。感病致死虫尸长出大量翠绿色分生孢子。孢子形状、大小等和分离前虫尸上的致病菌孢子形状大小一致.
According to “Koch” rule from 1984 to 1986, many indoor and field inoculation tests on the host Khynchites Coreanus Kono of Metarhizium iadini showed that the indoor lethality of adults was 89.3-100% , The control mortality rate was 0 ~ 5.9%, the lethal rate of larvae was 66.1% ~ 100%, and the control mortality rate was 0%. Guizhou Botanical Garden field control, adult mortality rate of 33 to 66.7%, corrected mortality rate of 53.3%, the control natural mortality rate of 12.5%. Sick dead insects grow a large number of emerald green conidia. The spore shape, size, etc., are similar to those of the pathogenic bacteria on the dead body before isolation.
