| 摘 要： | 通过1992—1978年的调查试验, 初步明确了以下事实:本地越冬的麦长管蚜尚未羽化, 田间已出现有翘成蚜;小麦苗期发现了穗期才能产生的穗型蚜;在冰冻期的高山上多次捕到有翅麦蚜;有翅成蚜大范围的“同期突发”现象;外来麦蚜占春季田间有翅蚜的98.8%以上.首次提出, 在有本地蚜源的情况下, 存在外来蚜源, 且外来蚜源可以成为春季田间麦长管蚜群的主体.本文分析讨论了迁入蚜源的可能基地和须进一步研究的问题.

| Abstract: | The investigation was conducted in Ningxia in 1972-1978. Evidences of long distance mi-gration of the grain aphid Macrosiphum avenae (Fabr.) are provided by the presence of alate form of the grain aphid before emergence of the local winged nymph, the appearance of the summer form aphids In spring which can only occur at the ear stage of wheat, the capture of the winged aphids in Liupanshan Mountain Meteorological Station in the freezing season, the presence of the winged aphids in different geography-ecological regions at the same time and the ratio of more than 98.8% of immigrant winged aplude in the spring population. It is ron-cluded for the firsf time that there is a long distance nugration of the aphid and the immigrant aphids are the main sources of the grain aphid in Ningxia in spring time .Regions possibly supplying immigrant aphids to Ningxia and the relevant problems to be studied in future are discussed. |
