用蚜量比值和千粒重降低比值法测定了小麦品种的耐害性。各品种蚜量排位和受害减产多少，反映出５种情况。耐害品种的耐害程度减产率低于各品种平均损失１５％，比感虫品种低３５％～５０％；田间蚜量增长慢，高峰期蚜发生量低１级。对指导药剂防治，控制种群数量，降低危害有一定作用。耐害性的大小与蚜虫摄取小麦氮素营养的难易有关。开展对蚜虫耐害性品种的选育有很实用的价值。
The resistance of wheat cultivars was determined by the ratio of aphids and the ratio of 1000-grain weight. The amount of aphids ranked and the number of victims reduced production, reflecting five kinds of situations. The harm reduction rate of resistant varieties was lower than the average loss of 15% of all varieties, 35% ~ 50% lower than the susceptible varieties; the amount of aphids in the field increased slowly, and the occurrence of aphids was only 1 at the peak. To guide the chemical control, control the number of populations, reduce harm have a certain effect. Resistant to the size of the aphids and nitrogen intake of wheat difficult to eat. Carrying out the breeding of aphid resistant varieties have very practical value.
