绿僵菌对马尾松毛虫的感染反应分析OA北大核心CSCDCSTPCD
Analysis and modeling of time-dose-mortality of Metarhizium anisopliae infecting larvae of Dendrolimus punctatus
通过以金龟子绿僵菌菌株M337和M104系列浓度的分生孢子悬液(1.0×1011-1.0 ×107个孢子·L-1)对马尾松毛虫幼虫的体表接种试验,测定马尾松毛虫对供试菌株的感染反应.运用时间-剂量-死亡率模型,对死亡率随时间和剂量的变化作了拟合,并与球孢白僵菌(Bb01和Bb02菌株)进行比较.接种后第10-12天绿僵菌M337菌株的LC50分别为1.86×109、1.52×108和1.67×10 7孢子·L-1,在浓度梯度为1.0×1011-1…查看全部>>
Two strains(M337 , M104 )of Metarhizium anisopliae at gradient doses in the suspension of 1.0 X 1011- 1.0 x 107 conidia·L-1 were bioassayed against larvae of Dendrolimus punctatus, and analyzed by contrasting with the biocontrol agent Beauveria bassiana ( Bb01 and Bb02). A time-dose-mortality model was applied to analyze the variation of mortality rates as affected by both time and dosage. The model showed considerable homogeneity in these isolates. 10…查看全部>>
