| 摘 要： | 利用8种不同类型的农药对美国白蛾3龄幼虫进行了致死效果试验。结果表明,4.5%高效氯氰菊酯乳油、25%高氯.辛硫磷乳油对美国白蛾致死速度最快,在36h的致死率均达100%。48%毒死蜱乳油、5.7%高氯.氟铃脲乳油在48h的致死率也达到了100%,3.2%阿维菌素乳油2000倍液在72h的致死效果达到了97.5%,0.2%甲氨基阿维菌素苯甲酸盐乳油1000倍液在72h的致死效果达到了90%。而5%氟铃脲乳油和5%灭幼脲乳油在72h对美国白蛾的致死率较低,仅分别达到27.6%、42.2%。

| Abstract: | We studied the mortal effect of eight pesticides against Hyphantria cunea 3rd instar larvae by immersion testing method.The results showed that the mortality rate of larvae was most quickly reached 100% after treatment of 4.5%cypermethrinemulsible Ec、25%cypermethrinemulsible·phoxim Ec in 36h.And the rate of death was also 100% after treatment of 48% dusipi Ec、5.7%cypermethrinemulsible·hexaflumuron Ec in 48h.The mortality rate was up to 97.5% 、90% respectively with the treatment of 2000-fold 3.2% abamectin Ec and 1000 time 0.2%emamectin benzoate Ec in 72h.While the mortality rate was still lower with the treatment of 5% hexaflumuron Ec and 5% chlorbenzuron Ec in 72h,the rate was only 27.6%、42.2% respectively. |
