| 摘 要： | 通过田间调查和室内饲养,昆明地区伪角蜡蚧的寄生性天敌有5种,其中蜡蚧扁角跳小蜂和绵蚧阔柄跳小蜂是主要寄生蜂,占寄生蜂总数的88.1%。寄生蜂的平均寄生率为13.4%。寄生蜂在大叶黄杨上部枝条的寄生率高于下部;阴面寄生率高于阳面和中间。伪角蜡蚧寄生蜂的种群空间分布用聚集度指标,Taylor幂法则和IWAO的m*-m回归分析法进行分析,得出伪角蜡蚧寄生蜂为聚集分布。

| Abstract: | Five species parasitic wasps of Ceroplastes pseudoceriferus Green were identified through field and laboratory Survey in Kunming.Anicetus ohgushii Tachikawa and Metaphycus pulvinariae(Howard) are the main parasitic wasps of Ceroplastes pseudoceriferus Green,constituting 88.1 percent of the total parasitic wasps.The pest was naturally parasitized by 13.4% in average.The parasitic rate was higher on the upper twigs of Euonymus japonicus Thunb than that of low,and the shady side than eutropic and middle.The spatial distribution pattern of the Parasitic wasps is aggregative distribution by using the aggregated index,Taylor's and Iwao's law. |
