用电子显微镜观察了意大利蜜蜂（Apismellifera）的腔顶感器（sensillumcoelocapitulum）。感器的表皮装置是一个蘑菇状的突起，没有孔，设置在一个狭窄的圆柱形坑位于中央的表皮，浅凹陷。可能有三个或四个受体细胞。三个受体细胞有不分支的感觉纤毛，含有密集的微管，其远端延伸到表皮装置，并完全填充其腔。这些连接纤毛是通常的9+0型。第四个感受器，如果存在的话，有一个薄的感觉纤毛，其终止于表皮装置之下。它的连接纤毛有武装外部双峰。外腔由两个包围的单元形成，并且完全密封。脂质沉积物存在于腔和造孔细胞内。泡囊细胞内腔周围有乳白色杆状结构。与其它昆虫的感受器进行了比较，讨论了昆虫感受器的共同特征。
The 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.
