摘要
采用5种杀虫剂对甜菜夜蛾进行田间药效试验。试验结果表明,5%氯虫苯甲酰胺悬浮剂、10%溴虫腈悬浮剂、15%茚虫威悬浮剂3种药剂具有很强的速效性和持效性,药后1 d防效达84.19%~89.66%,药后7 d防效达94.52%~97.76%。5%甲维盐水分散粒剂的速效性一般,但持效性较好,药后1 d和7 d防效分别为69.58%和94.65%。40%毒死蜱乳油速效性和持效性均最差,药后1 d和7 d的防效分别仅为57.18%和78.72%。
We evaluated the field control efficiency of five insecticides on larvae of Spodoptera exigua Htibner. The results showed that 5% chlorantraniliprole suspension concentrate （SC）, 10% chlorfenapyr SC and 15% indoxacarb SC had best rapid and durable effects among the five kinds of insecticides, with the control efficiency of 84.19%-89.66% at one day after the treatments carried out and the control efficiency of 94.52%-97.76% at seven days after the treatments implemented. While 5% emamectin-benzoate water dispersible granule （WDG） had common rapid effect but good durable effect, with the control efficiency of 69.58% and 94.65% at one day and seven days after the insecticide applied. 40% chlorpyrifos emulsifiable concentrate （EC） had the worst rapid and durable effects, with the control efficiency of 57.18% and 78.72% at one day and seven days after the insecticide applied respectively.
