摘要: 对棉蚜与其多种天敌在数、时、空方面关系的研究表明,龟纹瓢虫与棉蚜种群数量极相关,两者发生数量高峰期和低谷期均是同步的。龟纹瓢虫对棉蚜种群有明显的控制作用。龟纹瓢虫、草间小黑蛛及棉蚜种群的三维空间格局为聚集型,棉蚜和草间小黑蛛个体间互相吸引,龟纹瓢虫个体间互相排斥。

Abstract: Studies on the relationship between Aphis gossypii and its natural enemies in amount,time and space show that the amount of Propylaea japonica is closely related to that ofAphis gossypii, and they are synchronously occurred both at peak time and at lowestpoint.Propylaea japonica can significantly control by the occurence of Aphis gossypii.The three-dimensional spatial distribution patterns of Propylaea japonica, Erigonidiumgraminicola and Aphis gossypii are of aggregated type.The individuals of Aphis gossypiiand Erigonidium graminacopa are attracted each other, while those of Progylaea japonica.are repelled mutually.
