摘要
用改装的吸虫器对福建省古田县稻田周围杂草上寄生蜂进行调查 ,采集到寄生蜂 19科 78种 (或类 )。其中 ,绝大多数寄生蜂是稻田害虫的寄生性天敌 ;少数为重寄生蜂 (如螟蛉折唇姬蜂等 ) ;还有极少数种类既是害虫寄生蜂又是重寄生蜂 (如大痣细蜂等 )。这表明稻田周围杂草上贮藏着丰富的寄生蜂资源 ,是稻田寄生蜂的重要种库。适当保留稻田田埂的杂草和稻田周围的杂草地 ,有利于保护稻田寄生蜂资源 。
By using the modified suction device, a systematical investigation for the parasitoids in weeds around paddy field was carried out in Gutian county in 2001. A total of 19 Families, 78 species (or taxa) of wasps were collected. Most of them are parasitoids of rice insect pests, some are hyperparasite, and others are both parasitoids of rice pest and hyperparasite. The result showed that parasitoids were quite abundant in the weeds habitat and played an important role as a species pool of parasitoids in paddy field. Reasonable manipulation of weeds was good to conserve parasitoid resource and to improve the natural control effect of parasitoids on rice insect pests.
