| 摘 要： | 试验表明，４种杀虫剂对小麦蚜虫均有较好的防效。１０％吡虫啉可湿性粉剂（１０～２０ｇ／亩）、５０％抗蚜威可湿性粉剂（１０ｇ／亩）对麦蚜的防治效果为９１．２１％～１００％，优于４０％氧化乐果乳油２５～５０ｍｌ／亩和４０％久效磷乳油２５ｍｌ／亩，而对七星瓢虫成虫的杀伤率为１１．８％～６０．８％，明显低于４０％氧化乐果乳油和４０％久效磷乳油。

| Abstract: | The results of the trial showed that 4 Pesticides had a good control effect
to wheat aphids, Macrosiphum avenae (F.)and XRhopalosiphum padi (L.).Among them,the
control effects against wheat aphids of imidacloprid 10WP at the dosage of 1020 g/ mu and
pirimicarb 50WP at the dosage of 10g/ mu were 91.2%100%,which were better than those of
monocrotophos 40EC(2550 ml/ mu) and omethoate 40EC(25 ml/ mu ),and their killing rates to
adults of seven spot ladybird, Coccinella septimpunctata L.were 11.8%60.8%,which were much
lower than those of monocrotophos 40EC and omethoate 40EC. |
