【摘要】 在白蜡虫Ericerus pela(Chavannes)分布特征和天敌种类及其种群动态调查的基础上,对白蜡虫及其3种寄生蜂优势种白蜡虫花翅跳小蜂Microterys ericeri Ishii、白蜡虫阔柄跳小蜂Metaphycus ericeri Xuet Jiang和中华花翅跳小蜂Microterys sinicus Jiang在时间和空间上的数量分布进行了系统调查,测定出它们在时间和空间的一维生态位宽度、生态位重叠和比例相似性。结果表明,白蜡虫及其3种寄生蜂优势种的时间生态位宽度为:白蜡虫>白蜡虫阔柄跳小蜂>白蜡虫花翅跳小蜂>中华花翅跳小蜂,空间生态位宽度为:白蜡虫>白蜡虫花翅跳小蜂>白蜡虫阔柄跳小蜂>中华花翅跳小蜂。3种寄生蜂优势种与白蜡虫的生态位重叠为:白蜡虫花翅跳小蜂>中华花翅跳小蜂>白蜡虫阔柄跳小蜂,比例相似性为:白蜡虫花翅跳小蜂>白蜡虫阔柄跳小蜂>中华花翅跳小蜂,说明白蜡虫花翅跳小蜂与白蜡虫在资源序列上分布的相似性最大,在利用资源的相似程度最高。白蜡虫花翅跳小蜂与白蜡虫在时间上的同步性和空间上的同域性较强,为保护利用自然天敌提供了理论依据。在生态位测定的基础上,按生态位的理论观点,构建了时间-空间的二维生态位,评价了寄生性天敌对白蜡虫的跟随作用和寄生效能。更多还原

【Abstract】 The single-dimensional niche breadth,the niche overlap and the percentage similarity of Ericerus pela(Chavannes) and its three dominant species of parasite wasps were estimated by means of investigating their temporal and spatial niches on the base of distribution characteristics and species of parasite wasps and their populations dynamic of Ericerus pela(Chavannes).The results showed that temporal niche breadth of E.pela and its three dominant species of parasite wasps was E.pela>Metaphycus ericeri Xu et Jiang>Microterys ericeri Ishii>Microterys sinicus Jiang,and spatial niche breadth was E.pela>Microterys ericeri Ishii>Metaphycus ericeri Xu et Jiang>Microterys sinicus Jiang.niche overlap of three dominant species of parasite wasps and E.pela was Microterys ericeri Ishii>Microterys sinicus Jiang>Metaphycus ericeri Xu et Jiang,and percentage similarity was Microterys ericeri Ishii>Metaphycus ericeri Xu et Jiang>Microterys sinicus Jiang.These showed that Microterys ericeri Ishii and E.pela were the most similarity in the resources distribution and utilization.synchronism and sympatry of E.pela(Chavannes) and M.ericeri Ishii were both higher,which provided a theoretical foundation for protecting and utilizing natural enemies.The following effect and parasite efficacy of parasitoids of E.pela (Chavannes) were evaluated on the base of estimated niche,construct their two-dimensional temporal-spatial niches according to principle of niches.更多还原
