摘　　要：柑桔软蚧和褐软蚧两类蚧虫 ,在国外部分国家成为难以对付的害虫 ,主要是缺乏具有制约作用的寄生性天敌。目前在我国桔区为害并不严重 ,无须采取防治措施 ,这完全得益于寄生性天敌的自然控制作用。本文对浙江桔区这两类蚧虫的 14种寄生蜂的发生、分布及其天然制约作用进行了深入研究 ,以跳小蜂科 (Encyrtidae)的软蚧花翅跳小蜂、蜡蚧花翅跳小蜂、黑褐花翅跳小蜂、软蚧阔柄跳小蜂和蚜小蜂科的赖食软蚧蚜小蜂为优势种 ,寄生率高达 80 %～ 10 0 % ,在桔园只要有上述 5种中任何一种寄生蜂存在 。Two Soft Acales Coccus pseudomanoliarum Kuw. and C. hesperidum L. are difficult to be controlled in some oversea areas where parasitic wasps are not occurred. Presently,those two scales have no serious damage to the citrus plantings in China, since the natural control by parasitic wasps is effective. The results of the study on the occurrence, distrbution and natural control effect of fourteen parasitic wasps parasitized on two scales in Zhejiang citrus planting areas are presented. The results indicated that Microterys flovus How., M. ceroplastae Prirtsloo, M.sp and Metaphycus pulvinariae How. of Encyrtidae and Coccophagus iycimnia(Walks) of Aphelindae are predominant, the rate of parasitism is 80 100%. If any one of the above mentioned five species of parasitic wasp is occurred in the orchard, the damage caursed by those two scales could be controlled.
