摘　　要：在新疆伊犁地区１９９３ 年和１９９４ 年分别观察了１９５ 个和３６ 个麦类品种对麦双尾蚜Ｄｉｕｒａｐｈｉｓｎｏｘｉａ （ Ｍｏｒｄｖｉｌｋｏ） 的自然感虫性。３６ 个品种两年的结果进行比较表明， 感虫率级别相同的品种有１８ 个， 占５０ ％ ； 其中“一粒小麦”稳定地表现为不感虫性； 感虫率稳定地表现在２０ ％ 以下的品种有１３ 个， 即“８６２４２３３”、“京７７２”、“Ｍ８５１８９”、“Ｔ５７９”、“永良１３ ”、“Ｔ４９４”、“浮纳尔”、“Ｍｇ４５２１”、“广引７４”、“Ｍｇ５８２４”、“Ｍｇ８５８６”、“Ｔ１００８”和“短芒黑边红”； 感虫率稳定在２０ ％ ～４０％ 的品种２ 个， 即“额敏黑芒”和“白长穗”； 感虫率稳定在４０ ％ ～６０ ％ 的品种２ 个，即“黑芒红”和“勾毛白”。其余品种， 有１４ 个两年的感虫率相差一个级别（２０ ％ ） ； “黑芒长穗”、“高原６０２”、“伊宁黄库尔班”和“８２１０４２１１”等４ 个品种感虫率相差二个或三个级别。另外，１９９６ 年塔城引种试验的２ 个品种“春麦雄性不育系９０１”和“啤酒大麦（ 石引１ 号）”均遭受麦双尾蚜的严重为害。During the investigation period in Ili Prefecture, Xinjiang Uygur Autonomous Region, 195 and 36 wheat varieties were accessed for their susceptibility to Russian wheat aphid (RWA), ( Diuraphis noxia (Mordvilko)) in 1993 and 1994 respectively. Comparison of infestation grades among 36 wheat varieties by RWA in the two years showed that half of them were within the same grade. The aphid hardly attacked the “One kernel wheat”, Triticum monococcum. 13, 2 and 2 of these varieties consistently showed low (<20%), middle (between 20% and 40%) and high (>60%) infestation rates by RWA respectively. However, there are 18 other varieties displayed obvious change in their infestation grades. In addition, the varieties “Spring Wheat 901” and “Shiyin1 of Beer Barley” being introduced into Tacheng were seriously infested by RWA in 1996.
