| 摘 要： | A total of 12 strains of Metarhizium anisopliae Sorokin were tested for pathogenicity to Hylobitelus xiaoi,and a superior strain was used to infect trials in a forest.The results indicated that the strain Ma1291-2 had strong pathogenicity to H.xiaoi after treatment for 30 d by dipping inoculation with (1.5±0.5)×108 conidia·mL-1.The correct mortality,the muscardine cadaver rate and the conidia content individual of H.xiaoi were respectively 70.59%,70.81% and (1.90±0.34)×108 conidia individual,and the quickes...

| Abstract: | A total of 12 strains of Metarhizium anisopliae Sorokin were tested for pathogenicity to Hylobitelus xiaoi，and a superior strain was used to infect trials in a forest.The results indicated that the strain Ma1291-2 had strong pathogenicity to H.xiaoi after treatment for 30 d by dipping inoculation with (1.5 ±0.5)×10~8 onidia·mL~(-1).The correct mortality，the muscardine cadaver rate and the conidia content individual of H.xiaoi were respectively 70.59%，70.81% and (1.90±0.34)×10~8 conidia individual，and the quickest median lethal times (LT_(50)) were 13.89 d.The median lethal concentration (LC_(50)) was 1.135 3×10~6 conidia·mL~(-1).By infecting trials to H.xiaoi in a forest with the strain Ma12912，mortality of the treatment was extremely significant higher than the control，the correct mortality，the muscardine cadaver rate and the conidia content individual of H.xiaoi were 57.85%±1.19%，55.43%± 2.90% and (1.12±0.41)×10~8 conidia individual after 30 d，respectively，and the median lethal times (LT_(50)) was 16.56 d.The results suggest that the strain of Ma1291-2 has great application value. |
