云南白马雪山小地老虎蛾迁飞观察

Observations on The Migrations of The Black cutworm Moth (Agrotis ypsilon Rott.) on Baima Snow Mountain,Yunnan

摘要: 本文报道了小地考虑蛾迁飞活动与气候因子能源物质的相互关系。1985-1988年在云南白马雪山进行了三个全年的小地考虑蛾迁飞动态的系统观察，并测定比较了不同虫源的脂肪含量。结果表明，白马雪山一年有5次迁飞蛾峰。迁飞蛾种群动态与温度、湿度、降水、风速、气压和高空50000帕的西南及北风气流有密切关系。不同虫源的雌蛾脂肪含量差异显著，迁出型含量最高，本地型次之，迁飞过境型又次于前者，迁入型含量最低。

Abstract: This paper deals with the migrations of the black cutworm moth (Agrotis ypsilon Rott.) and the energy source and climative faetors.Observation stations were setting up on Baima snow mountain,Yunnan Province,and the throughout the year observed periodically the migratory population dynamics of the black cutworm moth,in 1985 to 1988.
