摘要
试验表明，辐射不育野蚕的田间释放比应为１６∶１～２０∶１，此释放比经济有效，其防治效果：第１～２代为７７２１％，第３代达８２３５％。由于大量收购田间采集的蛹作为田间释放不育蛹的虫源，收集区的防治效果达６１８％。两种方法相结合可取得双重防治效果，为防治野蚕开创了新途径。
he releasing proportion of sterile male moth and the combined effects of controlling the mulberry wild silkworm(MWS)in field were studied.The proportion of sterile wild silkworm to natural one was 16∶1 to 20∶1.The control effects in F 1 and F 2 generation were 77 21% and 82 35%, respectivcly.As a releasing pupal source of sterile wild silkworms,a large number of wild silkworm's pupae in field were purchased. When the purchased pupae were irradiated and released in field as sterile insects the control effect was 61 8%.
