| 摘 要： | 利用15种农药对3龄美国白蛾幼虫进行触杀效果试验,结果表明:15%阿维·毒死蜱乳油、0.5%二甲基二硫醚乳油、90%灭多威可溶性粉剂对白蛾的致死速度最快,在36 h时100.0%死亡;高效氯氰菊酯、S-氰戊菊酯、毒死蜱在48 h时达到了100.0%死亡;5%高效氯氟菊酯水乳型、20%高氯·马乳油、21%氰戊·马拉松乳油、40%杀扑磷乳油在72 h时达到100.0%死亡。5%丁烯氟虫腈乳油仅1 500倍液没有达到100.0%死亡,25%溴氰菊酯乳油、63.1%杀单·苏云可湿性粉剂和1.8%阿维菌素乳油1 000倍液在72 h的触杀效果达到96.7%,1%甲氨基阿维菌素苯甲酸盐泡腾片2 000倍液在72 h时致死作用最低为63.3%。另外,还对15种农药的毒力回归方程进行了拟合,并计算出15种农药的LC50。

| Abstract: | Three -years -old larvas of Hyphanatria cunea Drury were taken as objects to conduct drug sensitivity test by u -sing 15 kinds of pesticides, the results showed that 15% avermectin with chlorpyrifos EC, 0.5% dimethyl disulfide EC and90% methomyl soluble powder had the fastest killing speed to Hyphanatria cunea Drury, and the larvas were all died at 36h; beta -cypermethrin, S -fenvalerate and dursban tooke the second place with 48 h; 5% cyhalothrin, 20% bete -cypermethrinwith malathion EC, 21% fenvalerate with marathon EC and 40% methidathion EC reached 100 percent of dead in72 h.Only 1 500 times liquid of 5% butene -fipronil EC did not achieved 100.0 percent of dead.Insecticidal effects of25% deltamethrin EC, 63.1% monosulta· Bt WP and 1 000 times liquid of 1.8% avermectin were 96.7% in 72 h.2 000 times of 1% emamectin benzoate PP had the lowest lethal effets in 72 h, accout for 63.3%.In addition, regressionequation of the 15 kinds of pesticides was matched, and LC50 of 15 kinds of pesticides was calculateded . |
