摘　　要：为了探讨华山松木蠹象Pissodes punctatusLangor et Zhang有效的生物防治方法,在室内初步测定了3个粉拟青霉Paecilomyces farinosus株系对华山松木蠹象的感染致死率。结果表明:粉拟青霉RCEF0401,RCEF0402和RCEF0301这3个菌株对华山松木蠹象平均感染致死率分别为85%、85%和82.5%,三者间的感染致死结果无显著差异。The mortality of Pissodes punctatus infected by Paecilomyces farinosus was tested in lab. The result showd that the mortality of P. punctatus infected by the strain RCEF0401, RCEF0402 and RCEF0301 in the concentration of （ 1.7 - 108 ） spores/mL was 85 %, 85 % and 82.5 % respectively and there was no significant difference among these strains.
