麦长管蚜[Macroiphum averae(F)]是危害我省小麦的主要害虫之一。受其危害的小麦千粒重下降2.2~5.2克,一般损失产量10~20%,严重时损失40~50%,且面粉含糖量也明显下降。全省每年种植小麦600万亩以上,因麦蚜危害损失达8000万斤以上。研究麦长管蚜的生物学特性,可为预测预报麦蚜的发生规律及其综合防治提供依据。此项工作是在1986年12月~1988年2月进行的。
Macroiphum averae (F) is one of the major pests that endanger wheat in our province. The grain weight of wheat harmed by it decreased by 2.2-5.2 g, the general loss of yield by 10-20%, the loss by 40-50% in severe cases, and the decrease in flour sugar content. Every year more than 600 million mu of wheat is planted in the province, with the harm of wheat aphid reaching over 80 million kilos. To study the biological characteristics of Aphis gossypii could provide basis for predicting the occurrence and the comprehensive control of Aphis gossypii. This work was carried out from December 1986 to February 1988.
