采用稻茎浸渍法得出,2012年采集自湖北荆门的白背飞虱迁入种群有中等水平抗性(RR=16.07),迁出种群和回迁种群对田间吡蚜酮农药有高水平抗性。白背飞虱对田间吡蚜酮农药2012年度内抗性变化规律为迁出种群>回迁种群>迁入种群,说明湖北荆门白背飞虱种群对吡蚜酮的抗性在推进性激增。抗性治理迫在眉睫。
採用稻莖浸漬法得齣,2012年採集自湖北荊門的白揹飛虱遷入種群有中等水平抗性(RR=16.07),遷齣種群和迴遷種群對田間吡蚜酮農藥有高水平抗性。白揹飛虱對田間吡蚜酮農藥2012年度內抗性變化規律為遷齣種群>迴遷種群>遷入種群,說明湖北荊門白揹飛虱種群對吡蚜酮的抗性在推進性激增。抗性治理迫在眉睫。

Sample of Sogatella furcifera were collected from the rice elds of Jingmen City,Hubei Prov-ince and their pymetrozine resistance levels were monitored by using the rice seedling dipping method in 2012.The results showed that the immigration populations had the medium level of resistance to py-metrozine (RR=16.07),while the emigration population and return migration population had the higher level of resistance.The change regularity of pymetrozine resistance levels to Sogatella furcifera from Jing-men were emigration population>return migration population >the immigration population in 2012,in-dicating that the pymetrozine resistance was moving forward and increasing sharply.It is urgent to perform a resistance management program.
