麦长管蚜是小麦重要害虫之一。我省南北气温相差很大,地理条件及小麦种植方式(冬麦、春麦)也各不相同,发生迟早不一。为准确做好麦长管蚜的预测预报和大田防治工作,我们于1978-1979年,在全省不同地区设立基点,对麦长管蚜的发育进行了系统观察,初步了解该虫在各地的发育进度及其为害情况。在此基础上,分析了麦长管蚜在我省的发生区划。
Wheat aphid is one of the important wheat pests. The temperature difference between the south and the north of our province varies a lot. The geographical conditions and the way of planting wheat (winter wheat and spring wheat) are also different, which will change sooner or later. In order to accurately do the prediction and forecast of wheat aphids and field prevention and control work, we established a base point in different areas of the province from 1978 to 1979 to systematically observe the development of the wheat aphid, Developmental progress and its damage situation. On this basis, the division of wheat aphid in the province was analyzed.
