| 摘 要： | 在水稻生长后期，田间褐飞虱百穴虫量6000～10000头的大发生形势下，用25％吡蚜酮防治褐飞虱每667m^2用24g，药后3d与7d的防效分别为73．69％与64．92％；每667m^2用30g，药后3d与7d的防效为78．55％与70．19％，显著优于参试的乙虫腈与烯啶虫胺。建议隔15～20d再次用药。

| Abstract: | When the brown rice planthopper density was 6 000-10 000 insects/100 holes, the activity of 25% pymetrozine SC was tested on brown rice planthoppers in field. The results showed that the control effect of 3 d ,7 d at 24 g/667 m^2 were 73.69% and 64.92%, respectively. And the control effect of 3 d, 7 d at 30 g/667 m^2 were 78.55% and 70.19%, respectively. It was better than ethiprole and nitenpyram. It was recommended that 25% pymetrozine SC be sprayed again after 15-20 d. |
