摘要
[目的]通过田间药效试验从目前使用的杀蚜剂中筛选出对大豆蚜防效较好、对天敌杀伤力小的生物药剂。[结果]试验表明:苦参碱、除虫菊素具有良好的速效性和持效性,药后2 d的防效最高,药后10 d的防效为94%以上;吡虫啉、阿维菌素的速效性和持效性次之;抗蚜威的速效性和持效性差;药后10 d防效最低,为72%。[结论]5种试验药剂中,苦参碱对天敌影响小,是防治大豆蚜的良好生物农药。
The effective insecticides were selected to control soybean aphid（Aphis glycines） by field trials.[Results] Matrine and pyrethrin showed better rapid and durable effect,after treatment,the control effect was the highest after 2 days,the control effect was above 94% after 10 days.Imidacloprid and abamectin showed certain rapid effect and durable effect.Pirimicarb has poor rapid effect and durable effect and its highest control effect was only 72% after 10 days after treatment.[Conclusions] Matrine is a suitable insecticide for application and popularization of controlling A.glycines in field with little effect on natural enemies.
