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

摘要： 利用叶碟法(选择性和非选择性)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。亚洲玉米螟的蛀孔绝大部分在植株节间的下部，而该部位的丁布含量最高，这种现象值得进一步分析研究。
