| 摘 要： | 10种杀虫剂对玉米螟三龄幼虫的室内药效及毒力测定结果表明:40%毒死蜱乳油、40%辛硫磷乳油、25%吡虫·辛硫磷乳油、1.8%阿维菌素微乳剂4种药剂对玉米螟幼虫的防治效果速效性显著优于其他供试药剂;10%溴氰虫酰胺可分散油悬浮剂和20%氯虫苯甲酰胺悬浮剂,在达到相同防治效果的情况下,氯虫苯甲酰胺的用量是溴氰虫酰胺用量的1倍;辛硫磷与吡虫啉复配防治玉米螟幼虫具有显著的增效作用。

| Abstract: | Toxicity and efficacy of 10 kinds of pesticides against third instar larvae of Ostrinia rnacalis were studied indoor. The result showed that the control effect of four kinds pesticides of 40% chlorpyrifos EC and 40% phoxim and 25% imidacloprid phoxim EC and 1.8% avermectin microemulsion against Ostrinia rnacalis larvae was significantly better than other fast-acting drug test. Under the same control effect for 10% bromine cyantraniliprole dispersible oil suspensions and 20% chlorantraniliprole SC, the amount of chlorantraniliprole was double as much as bromo cyantraniliprole amount. Phoxim complex with imidacloprid against Ostrinia rnacalis larvae had significant synergies. |
