| 摘 要： | 采用叶片浸渍法,利用4种杀虫剂对稠李巢蛾的进行室内毒力测定,以期筛选高效、低毒的有效药剂,指导在扶芳藤上的稠李巢蛾的防治。结果表明:药剂处理24和48h后的室内毒力结果基本相同,稠李巢蛾幼虫对供试药剂的敏感程度依次为:1.8%阿维菌素乳油200g/L氯虫苯甲酰胺悬浮剂氯40%毒死蜱乳油0.3%印楝素乳油,其对稠李巢蛾3龄幼虫24和48h的LC50分别为1.96、7.18、12.53、276.46mg/L和1.19、1.03、6.30、184.40mg/L。建议在生产上采用阿维菌素和氯虫苯甲酰胺防治稠李巢蛾。 |

| Abstract: | By the method of leaf immersion,the toxicity of four insecticides to Yponomeuta evonymellus of Euonymus fertunei was tested in the laboratory,in order to screening effective drug of high efficiency,low toxicity of pest prevention and cure.The results showed that four insecticides had toxic activity to Y.evonymellus.The susceptibility of Y.evonymellus to these insecticides was ranked from high to low as following:avermectin>chloraniliprole>chlorpyrifo>azadirachtin,the LC50 of them after 24 h and 48 h treatment were 1.96,7.18,12.53,276.46 mg/L and 1.19,1.03,6.30,184.40 mg/L respectively.As a conclusion,we recommended avermectin and chloraniliprole as alterative chemicals to control this insect pest. |
