| 摘 要： | 桔绵蜡蚧(Pulvinaria citricola Kuwana)有捕食性天敌昆虫2种, 隶属于鞘翅目的瓢虫科; 寄生性天敌昆虫有8种,隶属于膜翅目小蜂总科的跳小蜂科和蚜小蜂科,其中日本食蚧蚜小蜂(Coccophagus japonicus Compere)为桔绵蜡蚧的主要寄生蜂,其数量占寄生蜂总数的71.2％,其数量变化将影响寄生蜂的整体消长变化。寄生蜂对桔绵蜡蚧的寄生率为40%.

| Abstract: | Pulvinaria citricola Kuwana was found that there are 2 specis of its predatory natural enemies belonging to Coccinellidae, and 8 species of its parasitic natural enemies belonging to Encyrtidae and Aphelinidae. Pulvinaria citricola Kuwana was the most impotent parasitoid of the pest, which occupied 72.2% of all parasitoids in number. The change of population dynamics of the parasitoid above would effect the fluctuation of whole parasitoid community. The parasitoid natural enemies of Pulvinaria citricola Kuwana's parasitic rate is 40%. |
