摘 要：
室内测定了黄蝉花素对斜纹夜蛾幼虫的抑制生长发育活性。结果表明,黄蝉花素对斜纹夜蛾幼虫的抑制生长发育活性与其处理浓度具有一定的相关性。与对照相比,处理组食物消耗量减少,幼虫生长发育被抑制,发育历期延长。处理组幼虫在蛹期不能正常化蛹而形成畸形蛹,羽化后的成虫表现为形态畸形。在预蛹期和蛹期由于不能正常蜕皮导致死亡率较高。研究显示黄蝉花素作为一类新型的昆虫生长发育控制剂或害虫田间种群管理的先导化合物值得进一步研究。

摘 要：
The insect growth inhibitor activity of allamdin was evaluated against Spodoptera litura(Fabricius) in the laboratory. The growth regulatory activity was found to be depended on the concentration of allamdin. Compared to the control larvae, the amount of food intake was reduced, the growth of larvae was inhibited, and the development of larvae was prolonged. The treated larvae molted to malformed pupae in the pupal stage and the moths after emergence exhibited morphological defect. A higher percentage of mortality at the prepupal and pupal stages was found and caused by moult disruption. The work shows that allamdin needs to be further studied as a lead compound for a novel potential insect control agent or for pests field population management.
