Abstract：
The fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), is a globally significant agricultural pest, causing severe damage to corn production in China. Chemical odor-based trapping is a major approach for FAW control, making it essential to understand the FAW antennal sensillum types to enhance development of effective chemical odor attractants. In this study, we comprehensively examined the antennal sensilla types of FAW, identifying eight types and two subtypes, including Böhm\'s bristles, sensilla trichoidea, sensilla chaetica (I and II), sensilla coeloconica, sensilla styloconica, sensilla squamiformia (I and II), sensilla auricillica, and sensilla basiconica. Sensilla chaetica II, and sensilla squamiformia II are reported for the first time for FAW in this study. Detailed low-voltage field emission scanning electron microscope (LVSEM) images and descriptions are provided for each sensillum type. This study provides the morphological information to aid in conducting antennal sensillum neurophysiological tests on FAW. RESEARCH HIGHLIGHTS: The types of sensilla of fall armyworm were examined, identifying eight types and two subtypes, including Böhm\'s bristles, sensilla trichoidea, sensilla chaetica (I and II), sensilla coeloconica, sensilla styloconica, sensilla squamiformia (I and II), sensilla auricillica, and sensilla basiconica. Detailed low-voltage field emission scanning electron microscope images and descriptions were provided for each sensillum type.
摘要：
秋季粘虫（一汽），节食夜蛾（J.E.史密斯）（鳞翅目：夜蛾科），是一种全球性的农业害虫，严重损害了中国的玉米生产。基于化学气味的捕获是一汽控制的主要方法，使了解一汽触角敏感类型以增强有效化学气味引诱剂的开发至关重要。在这项研究中,我们全面考察了一汽的触角感类型，识别八种类型和两种亚型，包括Böhm的刷毛,敏感的毛滴虫，财智（I和II），仙人掌，敏感的Styloconica，sensillasquamiformia(I和II),sensillaauricillica,和sensillabasiconica。仙草二世，在这项研究中，首次报道了一汽的sensillasquamiformiaII。为每种敏感类型提供了详细的低压场发射扫描电子显微镜（LVSEM）图像和描述。这项研究提供了形态学信息，以帮助在一汽进行触角神经生理测试。研究重点：研究了秋季粘虫的感官类型，识别八种类型和两种亚型，包括Böhm的刷毛,敏感的毛滴虫，财智（I和II），仙人掌，敏感的Styloconica，sensillasquamiformia(I和II),sensillaauricillica,和sensillabasiconica。为每种敏感类型提供了详细的低压场发射扫描电子显微镜图像和描述。
