云南农业大学植物保护学院及农学与生物技术学院研究人员采用浸渍法,在室内生物测定了金龟子绿僵菌KMa0107菌株对马铃薯块茎蛾2~4龄幼虫的毒力,并运用“时间-剂量-死亡率”模型分析了其致死剂量和致死时间等致病效应。结果表明,绿僵菌KMa0107菌株对马铃薯块茎蛾幼虫具有良好的侵染致病作用,接种处理后各龄幼虫的感病死亡率随接种密度的升高而增加,当用 Institute of Plant Protection and Agronomy and Biotechnology, Yunnan Agricultural University, Institute of Agronomy and Biotechnology using immersion method to determine the toxicity of M. anisopliae KMa0107 strains to 2-4 instar larvae of potato tuber moths in laboratory indoor, and using “time-dose- Mortality ”model to analyze its lethal dose and lethal time and other pathogenic effects. The results showed that Metarhizium anisopliae KMa0107 had a good infective pathogenic effect on potato tuber moth larvae. After inoculation, the susceptible mortality of each instar larvae increased with the inoculation density,
