| 摘 要： | 田间试验结果表明，四种杀虫剂对小麦蚜虫均有较好的防效。其中１０％吡虫啉可湿性粉剂１５０－３００ｇ／ｈｍ＾２，５０％抗威可湿性粉剂１５０ｇ／ｈｍ＾２对麦蚜的防治效果为９１．２１－１００％，倨于４０％氧乐果乳油１０００－２０００倍及４０％久效磷乳油２０００倍；而对在敌昆虫七星瓢虫成虫的杀伤率为１１．８－６０．８％，明显低于４０％氧乐果乳油１０００２０００倍及４０％久效磷乳油２０００倍。

| Abstract: | The results of field trial showed that 4 pesticides gave good control effect against wheat aphid,Macrosiphum avenae(F.) and Rhopalosiphum padi (L.).Among them,the control effect against wheat aphid of imidacloprid 10WP at rate of 150300g a.i./ha and pirimicarb 50WP at rate of 150g a.i./ha were 91.210%,which were better than that of monocrotophos 40EC(110002000)and omethoate 40EC(12000)and their killing rate to adults of seven spot ladybird Coccinella septempunctata L.were 11.8`.8%,which were much lower than that of monocrotophos 40EC(110002000)and omethoate 40EC(12000),which were 100%. |
