中文摘要：

用扫描电镜观察研究亚洲玉米螟幼虫的触角、口器附肢下颚须及其瘤状体、下唇须上的化学感受器的种类、分布与形态特征。亚洲玉米螟幼虫触角分为三节，在第二和第三节上主要有6个丹锥感受器和1个栓锥感受器两种化学感受器。口器附肢下颚须上有8个丹锥感受器，排列为3-2-2-1；下颚须瘤状体上各有一个侧栓锥和中栓锥感受器，另有一个较小的丹锥感受器；下唇须在第二节、第三节上各着生有一个丹锥感受器。亚洲玉米螟幼虫触角上化学感受器数量少，主要分为两种丹锥感受器和栓锥感受器；口器附肢下颚须及其瘤状体、下唇须上化学感受器数量较多，主要为丹锥感受器、侧栓锥和中栓锥感受器。

英文摘要：

The chemoreceptors on antennae and mouthparts of the larva of Ostrinia furnacalis Guenée were observed using scanning electron microscopy. Two kinds of chemoreceptors on antennae of the larva were six sensilla basiconica on the second and third segments respectively, and one sensilla styloconicum on the third segment of the antennae. The maxillary palpus of mouthparts appendages owned eight sensilla basiconica chemoreceptors array 3-2-2-1, and its strumae owning one lateral sensilla styloconicum, one medial sensilla styloconicum and one sensilla basiconica. There were two sensilla basiconica chemoreceptors on the second and third segments of labial palpus. The antenna of larva Ostriniafurnacalis owned few chemoreceptors, which were mainly sensilla basiconica and sensilla styloconicum. The mouthparts appendages had a variety of chemoreceptors, which were mainly sensilla basiconica, lateral sensilla styloconicum and medial sensilla styloconicum.
