| 摘 要： | 应用环境扫描电镜对奇步甲幼虫触角、下颚须、下唇须和尾突感器进行观察，对各类感器的数量、长度及分布特点等进行描述，并探讨各类感器的功能。结果表明：触角上分布有毛形感器和4类锥形感器；下颚须上分布有4类锥形感器、指形感器、腔锥感器、钟形感器、栓锥感器和圆形表皮领感器；下唇须上分布有5类锥形感器、腔锥感器和钟形感器；尾突上分布有毛形感器和3类锥形感器。钟形和毛形感器起机械性刺激感受作用；锥形感器起化学感应作用；指形感器和腔锥感器兼具机械性刺激感受和化学感应功能；栓锥和圆形表皮领感器首次在奇步甲幼虫上发现，其功能未知。 |

| Abstract： | By using the technics of scanning electron microscope (SEM), the shape, amount and distribution of the antennal, maxillary and labial palps, urogomphi sensilla of the larva Carabus prodigus were observed and their function were discussed. There were sensilla trichoidea, sensilla basiconica, sensilla digitifomia, sensilla coeloconia, sensilla campaniformia, sensilla styloconicum and cuticle collared sensilla on the larvae. Sensilla campaniformia and sensilla trichoidea are mechanoreceptors; while sensilla basiconica are chemoreceptors. Sensilla digitifomia and sensilla coeloconia can be both mechanoreceptors and chemoreceptors, sensilla styloconicum and cuticle collared sensilla are firstly discovered in ground beetle larvae, and their function are unknown so far. |
