蚜虫是麦田中的一大类重要害虫。其危害性极大,不仅通过大量取食植株汁液造成麦类植林生长迟缓,而且传播多种病毒,时常造成麦类作物的大量减产。近年来,由于大气环境的一系列变化,气温升高、干旱频繁等气候因子的影响,使麦蚜发生有逐年严重的趋势,同时种类组成也有了一些变化。为了更好地为农业生产服务,使麦类蚜虫的普查和测报工作更加准确无误,本文给出了目前已知的我国麦类蚜虫的种类系统检索。 Aphids are a large group of important pests in the field. Its great harm, not only by feeding large amounts of plant juice caused by slow growth of wheat plantations, and the spread of a variety of viruses, often resulting in large-scale wheat crop production. In recent years, due to a series of changes in the atmospheric environment, climatic factors such as high temperature and frequent droughts, the occurrence of wheat aphids has been a serious trend year by year. At the same time, species composition also has some changes. In order to better serve agricultural production and make the investigation and reporting of wheat aphids more accurate, this paper gives a systematic search of the known wheat aphids in China.
