摘要: 对1983、1984、1986、1988、1994和1995年6年棉花铃期以前棉蚜种群数量与其天敌种群数量以及各种天敌的捕食量,利用灰色系统理论和方法,研究天敌的日捕食总量和棉蚜种群数量的追随关系,并分析各种天敌与理想优势种天敌之间的联系程度,结果表明,龟纹瓢虫是棉蚜的主要天敌,其次是大草蛉,第三是八斑球腹蛛和草间小黑蛛.

关键词: 优势种天敌, 棉蚜种群, 捕食量, 灰关联度

Abstract: The populations of Aphis gosspyii and its natural enemies before cotton boll stage were investigated systematically in 1983, 1984, 1986, 1988, 1994 and 1995. The relationship between daily total predation of natural enemies and Aphis gosspyii population size was studied with the grey system theory and method, and the relational grade of various natural enemies to ideal superior natural enemies was analyzed. The results show that Propylaca japonica was the major natural enemy influencing Aphis gossypii, followed by Chrysopa septempunctata, then by Therdion octomaculatum and Erigonidium graminicola.

Key words: Dominant natural enemy, Aphis gossypii population, Predation, Grey relational grade
