摘要通过电子显微镜对体腔头感器（蜜蜂 Apis mellifera 的一种感受湿度和温度的感觉器）进行了研究。感觉器的角质器是一个蘑菇状的突起，没有孔，位于一个狭窄的圆柱形凹坑中，该凹坑位于角质层浅凹陷的中心。可能有三个或四个受体细胞。三个受体细胞具有不分支的感觉纤毛，含有致密的微管，微管向远端延伸到角质层装置并完全填充其空腔。这些连接纤毛是常见的 9+0 类型。第四个受体（如果存在）具有薄的感觉纤毛，其终止于角质层装置下方。它的连接纤毛具有武装的外部双联体。外腔由两个包络单元形成并且完全密封。脂质沉积物存在于腔和tormogen细胞内。产卵细胞在内腔周围具有蜈蚣棒状结构。通过与其他昆虫的比较，讨论了昆虫吸湿和吸热感受器的共同特征。
SummaryThe sensillum coelocapitulum, a hygro- and thermoreceptive sensillum of the honey bee, Apis mellifera, was investigated by electron microscopy. The cuticular apparatus of the sensillum is a mushroomshaped protrusion, devoid of pores, set in a narrow cylindrical pit positioned centrally within a cuticular, shallow depression. There may be three or four receptor cells. Three receptor cells have unbranched sensory cilia, containing densely packed microtubules, which extend distally into the cuticular apparatus and completely fill its cavity. These connecting cilia are of the usual 9+0 type. The fourth receptor, if present, has a thin sensory cilium which terminates beneath the cuticular apparatus. Its connecting cilium has armed outer doublets. The outer cavity is formed by two enveloping cells and is completely sealed off. Lipid deposits are present within the cavity and the tormogen cell. The thecogen cell has scolopale rod-like structures around the inner cavity. Features common to the insect hygro- and thermoreceptive sensilla are discussed in comparison with those of other insects.
