麦长管蚜是新疆80年代以来小麦上蚜虫的优势种。多年调查表明,麦长管蚜发生轻重主要受三个因子即冬春麦种植比例、不同熟期冬麦品种面积和小麦生育期间天气的制约。冬、春麦种植比例为1:3或3:1,冬麦中晚熟品种种植面积大,春季无强寒潮天气,南疆5月和北疆6月气温在20—24℃的天数在20天以上,则麦长管蚜发生重,反之则轻。
Wheat aphid is a dominant species of aphids on wheat in Xinjiang since the 1980s. Years of surveys have shown that the severity of the occurrence of the aphid in wheat is mainly controlled by three factors, that is, the proportion of winter wheat grown, the area of winter wheat cultivated at different maturity stages, and the weather during wheat growth. Winter and spring wheat planting ratio of 1: 3 or 3: 1, winter wheat middle and late maturing varieties planted area, spring without strong cold tide, southern Xinjiang in May and northern Xinjiang in June at 20-24 ℃ days in more than 20 days , Then the wheat aphid occurred weight, otherwise light.
