As a result, fungal culture library housed 392 isolates of anamorphic entomopathogenic fungi was constructed. Then, their infectivity and pathogenicity were assessed. Consequently, 13 isolates showed infectivity against female Anopheles stephensi. Among them, 2 isolates of Lecanicillium spp and 3 isolates of Beauveria bassiana which showed higher infectivity were applied for bioassay of pathogenicity. As a result, high pathogenicity isolate which showed fewer than half of 50% lethal time value of control plot, and low pathogenicity isolate which showed equal level of the value compared with control were detected., 2009年度~2010年度科学研究費補助金研究活動スタート支援研究成果報告書, application/pdf, 21880004}, title = {昆虫寄生菌の亜致死性効果を利用したマラリア媒介蚊の新防除技術開発に向けた基礎研究}, year = {} }
