摘要
新疆伊犁和塔城冬、春麦田的麦双尾蚜Diuraphis noxia ( Mordvilko) 有虫株率和百株蚜量,与小麦播种时间密切相关。在小麦正常播种期内, 冬小麦晚播可以显著减少麦双尾蚜数量, 每晚播种10 天, 第二年麦双尾蚜有虫株率可以下降40 % ~70% ; 春小麦每晚播种10 天, 麦双尾蚜有虫株率增加30 % ~88 % 。
Incidences of Russian wheat aphid (RWA), Diuraphis noxia (Mordvilko), in relation to wheat planting date were investigated in Ili and Tacheng, Xinjiang Uygur Autonomous Ragion. The winter wheat planted early (Aug. 21~29) was attacked more seriously by RWA and with a higher infested rate. It was reduced by 40%~70% with the delay of planting date at every 10 day. The early planted (April 1~7 ) spring wheat, however, suffered lower infestation of the aphid and its infested rate was increased by 30%~88% with the delay of planting date at every 10 day.
