摘要
应用4株蝉拟青霉开展对小菜蛾致病性的研究。结果表明:4株蝉拟青霉分生孢子、菌丝对小菜蛾的致病性有一定差异,其中GZDXIFR4611的感染致死效果最好,孢子悬液的致死率可达到70%,菌丝悬液的致死率可达到65%,为将蝉拟青霉作为一类重要的生防真菌提供了参考数据。
To investigate the effect of pathogenicity of Paecilomyces cicadae(PC)to Plutella xylostella(L.),the insecticidal mortality of the 4 strains of PC were tested.The results showed that the spore and the hyphae of 4 strains of PC had great differences in the pathogenicity.The highest insecticidal mortality was GZDXIFR4611,whose mortality in spore suspension was 70% and in hyphae suspension was 65%.The results provided reference for the use of Paecilomyces cicadae as bio-control fungi.
