摘　　要：为筛选出高效安全的土壤处理杀虫剂,室内采用浸叶法比较了溴氰虫酰胺、氯虫苯甲酰胺、氟虫双酰胺与8种常规杀虫剂对小地老虎的毒力,用滤纸接触法和人工土壤法分别测定了11种药剂对蚯蚓的急性毒性,并通过盆栽试验比较了其对小地老虎和蚯蚓的选择毒性。结果表明,3种双酰胺类杀虫剂对小地老虎的室内毒力明显高于其它8种对照药剂,对蚯蚓的LC50均属于低毒级,其中以溴氰虫酰胺的毒力选择性最高。盆栽试验中双酰胺类药剂防虫效果均低于其它对照药剂,10%溴氰虫酰胺可分散油悬浮剂保苗效果显著高于5%氯虫苯甲酰胺悬浮剂和20%丁硫克百威乳油,且双酰胺类药剂对蚯蚓没有明显致死作用。说明在棉田选择溴氰虫酰胺能够控制小地老虎的危害。To screen effective insecticides, the laboratory toxicities of 11 insecticides to 3rd instar black cutworm Agrotis ypsilon （Rottemberg） were measured using leaf-dipping method. And both artificial soil method and contact filter method were used to determine the acute response of these insecticides to earthworm Eisenia foetida （Savigny）. In addition, pot experiment was done at the same time. The results revealed the toxicity of cyantraniliprole, chlorantraniliprole and flubendiamide were significantly higher than that of other eight insecticides. The acute response of these insecticides to earthworm showed that the LC50 values of cyantraniliprole, chlorantraniliprole and flubendiamide belonged to the inferior toxic category. The selective toxicity of cyantraniliprole was the highest. The control effect of three new amide pesticides to A.ypsilon was lower than that of other pesticides and they were all safe to earthworm using toxic soil method. There is no significant difference compared with the protection effect on seedling of 10% cyantraniliprole dispersible oil suspension and other pesticides, but significantly higher than 5% chlorantraniliprole suspension and 20% carbosulfan emulsifiable concentrate. In conclusion, cyantraniliprole could be chosen as the ideal pesticide against black cutworm A.ypsilon in cotton field.
