摘要
通过1983—1986年5—6月份棉田定点系统调查,1986年6月天敌与棉蚜空间格局动态的研究以及室内饲养功能反应的测定,根据作者(邹运鼎1986)提出的标准,从天敌、害虫两者数量、时间、空间三个方面关系综合评定、得出龟纹瓢虫是棉花苗期棉蚜的捕食性天敌优势种。
Systematic investigations were conducted in fixed spots of cotton fields during Mays to Junes of 1983—1986, and spatial pattern dynamics of natural enemy-Aphis gossypii Glover in June, 1986, laboratory rearing as well as measurement of functional response were studied. Based on the criterium (Zou Yunding, 1986), Propylaea japonica Thumb is justified integratedly as the predominant predator of Aphis gossypii in the seedling stage of cotton in the light of the relationships between numbers, time, and space.
