| 摘 要： | 利用叶碟法和取食称重法，测定并肯定了丁布对亚洲玉米螟的拒食作用。在叶碟法中，非选择性拒食率低于选择性拒食率。本实验结果表明，丁布对亚洲玉米螟的胚胎发育可能有一定的影响，对幼虫的生长发育有深刻影响，幼虫体重降低，发育迟缓，蛹重降低，并出现畸形蛹。

| Abstract: | The extracted DIMBOA was used to determine its biological activities onthe Asian corn borer (ACB),Ostrinia furnscalis (Guenee).The antifeedant prop-erty of DIMBOA on ACB was confirmed by the methods of leaf-disc (selected andunselected) and feeding-weighing.Antifeeding ratio in unselected experiment waslower than that in selected one.Our results showed that DIMBOA had some effecton embryonic development of ACB and significantly affected the growth and devel-opment of ACB's larvae.The larvae's growth and development were delayed,mor-tality increased,weight of both the larvae and the pupae decreased,sex ratio (f/m)decreased,and deformed pupae appeared after the treatment with DIMBOA.MostACB holes in plants are at the lower parts of internodes,where DIMBOA concen-trations are higher.Further researches on this phenomenum are needed. |
