| 摘 要： | 对青花菜上的桃蚜种群动态进行了田间调查,结果表明,11月中旬以前桃蚜数量较少,11月下旬后桃蚜数量剧增,至12月上旬达到高峰。应用干扰作用控制指数法评价了阿维菌素、蚜虱灭、蚜虱蓟净等杀虫剂对桃蚜种群控制的作用。药后1 d各处理对桃蚜的防效较低;药后3 d蚜虱灭、蚜虱蓟净处理的防效显著高于阿维菌素处理,其干扰控制指数IIPC分别为0.0117,0.0717,药后10 d,蚜虱灭、蚜虱蓟净处理的蚜虫数量仍保持很低密度,其IIPC分别为0.0010,0.0186,具有很高的防治效果。 |

| Abstract: | The population dynamic state of Myzus persicae in Broccoli was studied in this paper.The results showed that the density of peachaphid was very low before middle November,quickly increased in the late November and reached the peak in the early December.The interference index of population control,IIPC was used to evaluate the control effect of Avermectins,Yasimie and Yasimiejin on peach-aphid.The results showed that the three insecticides had less control effect after 1 day,but after 3 days the control effect of Yasimie and Yasimiejin was better than Avermectins,the IIPC were 0.011 7 and 0.071 7 respectively,while the IIPC were 0.001 0 and 0.018 6 ten days later,it showed that the two kinds of insecticides had higher control effect on peach-aphid. |
