通过扫描电子显微镜对欧洲向日葵蛾、Homoeosoma nebulella（鳞翅目：螟科）雄性和雌性触角、口器、跗节和产卵器上的感器进行了研究。触角鞭毛具有多孔感器（trichodea、basiconica、auricillica、coeloconica）和单孔感器（chaetica、styloconica）。毛感器（雄性 8300 个，雌性 6000 个）和基本感器（雌性 1150 个，雄性 650 个）的数量存在性别二态性。长鼻有单孔s。 styloconica, 多孔 . basiconica (首次在鳞翅目中描述), aporous s. chaetica 和一些罕见的单孔 s. basiconica 在食品频道。唇触窝器官内有多孔的触角。腔圆锥形，而上颌须有无孔感器。两性的跗节都拥有一种无孔的跗节。 chaetica 和 2 种单孔 s.查蒂卡。男女跗骨感觉器分布无显着差异。产卵器每个叶的表面都覆盖有 3 种类型的无孔表面。不同长度的毛虫和约60个多孔的毛虫。 basiconica，鳞翅目产卵器上不常见的感器。讨论了感器在产卵地点选择中的作用。
Sensilla on male and female antennae, mouthparts, tarsi and on the ovipositor of the European sunflower moth, Homoeosoma nebulella (Lepidoptera : Pyralidae) have been investigated by means of scanning electron microscope. The antennal flagellum bears multiporous sensilla (trichodea, basiconica, auricillica, coeloconica) and uniporous sensilla (chaetica, styloconica). A sexual dimorphism is found in the numbers of sensilla trichodea (8300 in males and 6000 in females) and sensilla basiconica (1150 in females and 650 in males). The proboscis has uniporous s. styloconica, multiporous s. basiconica (described for the first time in Lepidoptera), aporous s. chaetica, and some rare uniporous s. basiconica in the food channel. The labial palp-pit organ houses multiporous s. coeloconica, while the maxillary palps have aporous sensilla. Tarsi of both sexes possess one type of aporous s. chaetica and 2 types of uniporous s. chaetica. There is no significant difference in the distribution of tarsal sensilla between males and females. The surface of each lobe of the ovipositor is covered by 3 types of aporous s. trichodea of different lengths and about 60 multiporous s. basiconica, sensilla unusual on the ovipositor of Lepidoptera. The role of sensilla in the oviposition site selection is discussed.
