通过对棉蚜、棉铃虫及其6种捕食性天敌的时间生态位、空间生态位及时空二维生态位的研究,分析了棉蚜、棉铃虫对时间资源利用及其在群落中地位,评价了天敌之间相互关系和各种天敌对棉蚜、棉铃虫的跟随效应及控制作用。利用可变平均法对二维生态位重叠值的系统聚类分析结果表明,天敌的自然控制作用难以达到控制害虫的效果,必须协调应用多种措施综合防治。
By analyzing the temporal niche, space niche and space-time two-dimensional niche of cotton aphid, cotton bollworm and their predators, the effects of cotton aphid and cotton bollworm on the utilization of time resources and their status in the community The relationship between natural enemies and the effects of various natural enemies on cotton aphid and cotton bollworm and their control effects. The result of cluster analysis of two-dimensional niche overlaps using the method of variable average shows that natural enemies can not control pests effectively. Therefore, it is necessary to coordinate and apply various measures to prevent and control pests.
