| 摘 要： | 以常规防治农药甲胺磷做对照,比较高效低毒化学农药吡虫啉和天敌昆虫瓢虫对田间麦蚜的防治效果。结果表明,施用10%吡虫啉可湿性粉剂300ghm2药后5d和10d的防效分别为15.1%和31.1%,对麦蚜防效理想。释放天敌昆虫瓢虫后5d和10d的防效分别为-347.6%和-171.7%,防效差,这是由于释放天敌后的强降雨所致。

| Abstract: | With the treatment of methamidophos as control,the control efficiency of imidacloprid and natural enemy ladybirds on wheat aphids were compared in Hebei Province.It showed that after the chemical spray,the control efficacy of 10% imidacloprid 10WP at a rate of 300 g/hm 2 was 15.1% on the 5th day and 31.1% on the 10th day,respectively.While after the release of ladybirds,the control efficacy was -347.6% on the 5th day and -171.7% on the 10th day,respectively.The imperfect control efficiency of ladybirds ascribed to the heavy rain the day after the release. |
