| 摘 要： | 为了明确枸杞常用药剂对蜡蚧轮枝菌的抑制作用和蜡蚧轮枝菌对枸杞蚜虫的控制效果，采用测定抑菌率和室内毒力的方法对4株蜡蚧轮枝菌进行研究。结果表明：杀菌剂中的醚菌酯和杀虫剂中的啶虫醚对4株蜡蚧轮枝菌较安全|1号蜡蚧轮枝菌对枸杞蚜虫的控制效果最好，其浓度毒力回归方程为y=0.209 x+3.904，LD50为1.8×105个?mL-1，时间毒力回归方程为y=0.650 3x+1.840 4，LT50为4.89 d。

| Abstract: | To definite the chemical inhibition to Verticillium lecanii and control effect of V.lecanii to Aphis sp.,4 strains Verticillium lecanii were studied by methods of testing the percentage of bacterial inhibition and conducting bioassay in door.The results showed that the fungicide Kresoxim-methyl and the insecticide Acetamiprid were safe to V.lecanii.Conduct results showed that No.1 strain was the best.LD50 and LT50 of which were 1.8×105 spores·mL-1(regression equation y = 0.209x + 3.904)and 4.89 days(regression equation y = 0.650 3x + 1.840 4),respectively. |
