| 中文摘要: |
| 触角和下唇须是昆虫头部的重要感觉器官，其上被有多种类型的感器。宽胫夜蛾Protoschinia scutosa是一种重要的农业害虫，但其触角和下唇须感器研究较少。本研究利用扫描电子显微镜观察了宽胫夜蛾的触角和下唇须感器的类型、分布和超微形态。宽胫夜蛾的雌雄触角均为丝状，雌虫触角鞭节明显短于雄虫。雌雄触角均分布有8种类型感器，分别为Bhm氏鬃毛、鳞形感器、毛形感器、刺形感器、耳形感器、锥形感器、腔锥形感器和栓锥形感器。其中，毛形感器数量最多，且雄性毛形感器的数量明显多于雌性。宽胫夜蛾的下唇须为长管状，雌雄下唇须长度无显著差异。共观察到5种类型感器，即毛形感器、钟形感器、鳞形感器、刺形感器和棒形感器。毛形感器分布在下唇须基部第1节和端部第3节的陷窝器内，钟形感器位于第1节毛形感器簇之中，鳞形感器在各节均有分布，刺形感器和棒形感器只见于第3节。并对宽胫夜蛾的触角和下唇须感器的功能进行初步的推测和讨论。为昆虫感器功能分析、分类学和行为学研究提供依据。 |

| Antennae and labial palp are important sensory organ on the head of insects, usually covered with various types of sensilla. Protoschinia scutosa is an important agricultural pest, but the antennal and labial palp sensilla remain unsatisfactorily explored. This study investigated the types, distribution and ultramorphology of the antennal and labial palp sensilla of P. scutosa using scanning electron microscopy. The antennae of both sexes of P. scutosa were filiform, but female flagellum was significantly shorter than male. Both sexes bear eight types of sensilla on antennae: Bohm’s bristles, sensilla squamiformia, s. trichodea, s. chaetica, s. auricillica, s. basiconica, s. coeloconica, and s. styloconica. Sensilla trichodea were the most abundant type among these sensillum types, and males possessed much more sensilla trichodea than females. The labial palp of P. scutosa was long tubular, and showed non-significant differences in length between sexes. Five types of sensilla were observed on the labial palp, sensilla trichodea, s. campaniformia, s. squamiformia, s. chaetica and club-shaped sensilla. Sensilla trichodea were located on the basal segment of labial palp and the distal labial pit organ, s. campaniformia were distributed among the cluster of s. trichodea on the basal segment, s. squamiformia were present on all three segments, and s. chaetica and club-shaped sensilla were only found on the distal segment. This study briefly predicted and discussed the function of antennal and labial palp sensilla, and would provide a foundation for functional analysis of insect sensilla, taxonomy and behavioral studies. |
