大量繁殖并助增性释放赤眼蜂控制各种鳞翅目害虫,其效果有优有劣。宽脉赤眼蜂(Trichogramma platneri Nagarkatti)防治鳄梨害虫楔卷蛾(Amorbia cuneanaWalsingham)和病状尺蠖(Sabulodesaegrotata(Guenee))效果较佳,然其大量人工繁蜂仍不易掌握。我们研究的主要目的就是要找出其原因。目前业已开始的商业性繁蜂主要是用麦蛾(Sitotroga cerea—lella(Olivier))卵。很显然有许多因子影响大批繁峰是否成 Trichogramma multiplication and help enhance the release of Trichogramma control a variety of Lepidoptera pests, its effect is excellent. Trichogramma platneri Nagarkatti is better than Amorbia cuneana Walsingham and Sabulodesaegrotata (Guenee), however, it is still not easy to master the large amount of artificial breeder. The main purpose of our study is to find out why. The commercial breeders that have now started are mainly the eggs of Sitotroga cereallus (Olivier). It is clear that there are a number of factors that have contributed to the peak
