蝉拟青霉对菜粉蝶幼虫有较强的致病性。田间试验,幼虫期喷洒2.4～1.8孢子,ml孢子悬浮液,感病率达65～70％。而在卵期施菌,可使90％初孵幼虫感病死亡。此菌可在一些自然基物上培养,能形成大量分生孢子,室温下贮存一年不失活性 Paecilomyces Paecilomyces larvae cabbage have a stronger pathogenic. Field trials, larvae spraying 2.4 to 1.8 spores, ml spore suspension, the prevalence of 65 to 70%. In the egg application of bacteria, can make 90% of newly hatched larvae susceptible to death. The bacteria can be cultured in some natural substrates, can form a large number of conidia, stored at room temperature for one year without loss of activity
