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Ｄｉｕｒａｐｈｉｓｎｏｘｉａ （ 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“８６２４２３３”、“京７７２”、“Ｍ８５１８９”、“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“８２１０４２１１”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。
In 1993 and 1994 in Yili Prefecture of Xinjiang, the natural susceptibilities of 195 and 36 wheat cultivars to Diu raphisnoxia (Mordvilko) were observed. The comparison of the results of 36 varieties for two years showed that there were 18 varieties with the same level of susceptibility, accounting for 50% of the total. Among them, “one grain of wheat” showed stable insensitivity; the rate of susceptible insects was stable below 20% There are 13 varieties, namely “86 2 4 2 3 3”, “Beijing 772”, “M85 189”, “T579”, “Yongliang 13”, “T494” , “Mg4521”, “Guangyin 74”, “Mg5824”, “Mg8586”, “T1008” and “Shuangbianbianbianhong”. The susceptible rate was 20% ~ 40% Black Mountain “and” White Long Spike “. The susceptible rate was stable at 40% -60% of the 2 varieties, namely” Black Mountain Red “and” Furong White “. The remaining varieties, there are 14 two years the rate of a sense of insects a difference (20%); ”Black Mountain long spike“, ”plateau 602“, ”Yining yellow Qurban“ and ”82 10 42 1 1 “and other four varieties of susceptible rate difference between two or three levels. In addition, two varieties of ”Triticum aestivum male sterile line-901“ and ”Beer barley (Shi-Yin-1)" were introduced into Tacheng in 1996 and suffered severe damage to the wheat aphid.
