摘要
对山东桃园山楂叶螨、桃一点斑叶蝉及其主要天敌的时间、空间和时间—空间二维生态位宽度和生态位重叠进行了研究。结果表明,主要天敌异色瓢虫、七星瓢虫、龟纹瓢虫、大草蛉和蜘蛛与该2种害虫在时间上的同步性和空间上的同域性均较强,为保护利用天敌控制该2种害虫提供了依据。
The temporal, spatial and two-dimensional niche breadth and overlap of Tetranychus viennensis Zacher, Erythroneura sudra Distant and their major natural enemies were studied in Shandong. The results showed that the synchronism of time and the sympatry of space between the pests and their natural enemies, such as Harmonia axyridis, Coccinella septempunctata, Propylaea japonica and Chrysopa septempunctata were both stronger, which provided a foundation for protecting and using natural enemies to control those pests.
