1974—1986年在济南调查,未见麦长管蚜在小麦和其他植物上产卵越冬。其成、若蚜耐高、低温能力差,室内饲养冬、夏不能存活,田间除特殊环境外,不能越冬渡夏。调查结果表明,麦长管蚜在1月0℃等温线以南地区可以越冬,在7月26℃等温线以北地区可以越夏;有翅蚜量存在“突增”、“突消”现象,在高山与平地,海岛与陆地出现时间一致,在我国东部地区的发生期南北方相互衔接。据此认为我国东部地区麦长管蚜存在迁飞问题,并提出了有翅蚜迁飞路线和发生区域。
In 1974-1986, a survey was conducted in Jinan. No wheat aphid was found to lay eggs in winter wheat and other plants. As a result, if the aphids high tolerance, low temperature ability, indoor feeding winter, summer can not survive, in addition to special circumstances outside the field, can not wintering summer. The results showed that the wheat aphid could winter in the area south of the 0 ℃ isothermal in January and the summer in the area north of the isothermal 26 ℃ in July. There was a phenomenon of “sudden increase” In the mountains and plains, the island and the land appear the same time, in the eastern part of our country occurs north and south convergence. According to the above, we think that there is a problem of migrating wheat aphid in the eastern part of our country, and proposed the relocation route and occurrence area of winged aphids.
