| 中文摘要: |
| 应用活体增殖病毒 ,制备甘蓝夜蛾核型多角体病毒杀虫剂乳剂 ,室内对 4龄甘蓝夜蛾幼虫的毒力测定 ,其LD50为9.42×103PIB/头。田间防治效果表明 ,采用1.0×1011PIB/hm2 和3.0×1011PIB/hm2的剂量防治甘蓝夜蛾的效果都在70%以上。乳液的稳定性较好 ,粘着性较强 |
| 英文摘要: |
| The propagation of MbNPV (Mamestra brassicae nuclear polyhedrosis virus) in vivo and production of the virus as insecticidal emulsion were studied. Agglutination and stability of this emulsion were well. Results of bioassay for cabbage moth showed that the LD50 of the emulsion was 9.42×103PIB/larva. In the field tests, dosages of 1.0×1011 PIB/ha and 3.0×1011PIB/ha caused more than 70% mortality of larvae on Chinese cabbage. |
