摘  要:
在新疆塔城地区, 麦双尾蚜Diuraphis noxia ( Mordvilko) 分布在塔城市、额敏县、裕民县、托里县和布克赛尔县, 夏季气候干热的乌苏县和沙湾县未发现麦双尾蚜。根据两年田间试验确定冬、春小麦的防治指标( 被害株率) 分别为2-8% ~11-9 % 和1-0 % ~6-2 % , 麦双尾蚜发生较重的年份和小麦生长早期防治指标较严。在塔城地区, 大部分年份麦双尾蚜受自然控制因素制约而为害较轻。

摘  要:
The Russian wheat aphid (RWA), Diuraphis noxia (Mordvilko), distributed in five of the seven counties in Tacheng, Xinjiang Uygur Autonomous Region. The aphid could cause great damage to wheat in some areas in certain years. The economic thresholds (RWA infestation rate) ranged from 2 8% to 11 9% for winter wheat and from 1 0% to 6 2% for spring wheat depending on their growing stages and incidence of the aphid. In most years, the aphid was controlled under natural regulators, especially its natural enemies and no insecticide application was needed.
