| 中文摘要: |
| 本文采用扫描电镜技术对钩纹皮蠹雌、雄成虫触角的形态特征及其上感器的种类、分布和数量进行研究。结果表明, 钩纹皮蠹雌、雄成虫触角均为锤状, 共有4种感器类型, 即刺形感器、锥形感器、毛形感器和B?hm氏鬃毛, 其中, 刺形感器有3种亚型, 锥形感器有2种亚型。钩纹皮蠹雌、雄成虫触角的鞭节7~9节 (F7~F9) 上有丰富的感器, 是感知外界信息刺激最敏感的部位, 雌、雄成虫触角间感器的类型及分布位置没有明显的差异, 但各感器的数量存在性二型现象; 锥形感器为嗅觉感器, 可以辨别不同寄主的气味, 毛形感器可以感受性信息素, 在寻找配偶方面扮演重要角色。 |
| 英文摘要: |
| The external morphological characteristics, types and distribution of antennal sensilla of Dermestes ater De Geer were observed under scanning electron microscope. The results showed that the antennae of female and male adults were hammer-shaped. Four types of sensilla including sensilla chaetica, sensilla basiconica, sensilla trichodea and Bhm bristles were found, of which sensilla chaetica included three subtypes and sensilla basiconica included two subtypes. The 7th to 9th flagella (F7-F9) are most sensitive part on antennae with rich sensory receptors responding to outside information. There was no obvious difference in the types and distribution of antennal sensilla for male or female, while significant sexual differences were observed in the numbers of each type of sensilla. Sensilla basiconica is an olfactory sensor that can identify the smell of different hosts, and sensilla trichodea is responsible for perceiving sex pheromones and plays an important role in spouse finding. |
