| 摘 要： | 花角蚜小蜂(Physcus fulvus Compere et Annecke)是我国矢尖蚧产卵雌成虫的一种主要的体内寄生蜂。以幼虫和蛹越冬。在四川7～10月是全年中该蜂虫口最多的时期,寄生率最高时可达71.6%,年平均19.0%。在这段时间内桔园应避免喷用化学农药,以保护天敌。5～6月是药剂防治害虫取得最佳效果的时期,亦是对本种蚜小蜂伤害最少的时期。

| Abstract: | Physcus fulvus Compere et Annecke is a major endoparasite of the ar-rowhead scale (Unaspis yanonensis Kuwana).It overwinters as both larvae and pupae in host body.The peaks of parasitism often appears from July to October.The highest parasitic rate had been observed as 71.6%,the annual being 19% average.Sophisticated insecticidal spray can easily control the increasing pest population in May and June with minimal injury to the parasitic wasps. |
