摘要
本文报导以赤眼蜂蛹作替代饲料饲养捕食性瓢虫初步试验的结果。以赤眼蜂蛹饲养四斑月瓢虫、龟纹瓢虫和七星瓢虫,结果表明赤眼蜂蛹能基本满足三种瓢虫生长发育的需要;发育历期分别为11.9天(27℃)、9.7天(27.5℃)和17.5天(25℃),成虫获得率分别为82.05％、78.4％和70.6％。以赤眼蜂蛹连续饲养四斑月瓢虫12代。
The success in the development of artificial host eggs for Trichogramma in China has made it possible to produce large numbers of Trichogramma pupae all the year round. Tests on rearing predacious coccinellid on Trichogramma pupae are carried out in order to spread to utilization of artificial eggs for Trichogramma. Three species coccinellids-Menochilus quadriplagiata, Propylea japonicaand Coccinella septempunctata are reared. The results show that Trichogramma pupae basically satisfy nutritional needs completing their development from larvae to adult. The obtained adult rate is 82.05%, 78.40% and 70.60% respectively. Twelve generations of Menochilus quadriplagiata and three generations of Propylea iaponica are reared on Trichogramma pupae.
