The external morphology and distribution of antennal sensilla of Glenea cantor Fabricius were studied with scanning electron microscopy. The antennae of G. cantor were observed to be filiform, consisting of scape, pedicel, and flagellum (nine flagellomeres). Four distinct types of sensory receptors were observed, including sensilla chaetica, sensilla trichodea, sensilla basiconica, and Böhm bristles. Three morphological subtypes of sensilla chaetica were found on the antennae, and sensilla trichodea were also categorized into three morphological subtypes. Sensilla basiconica was grouped into two morphological subtypes that were found on subsegments F2-F9 of the flagellum, and Böhm bristles were only found at the intersegmental joints between the scape and the head and between the scape and the pedicel. The antennae of male and female adults were similar in shape, length, and diameter. However, the length, diameter, distribution, and number of each of the four distinct types of sensilla on the males were significantly different from those on females. The types, lengths, diameters, numbers, and distributions of these sensilla were described, and their possible functions were also discussed. The results indicated that the base and end of an antennal segment have a similar sensillum density, but the middle section sensor density is significantly greater, especially for olfactory and gustatory sensilla, possibly because the joints are more involved in mechanical sensing. The density of sensors is closely related to its sensing function; so, future studies on the biology of olfaction and sexual communication in G. cantor will be facilitated by these observations.

成年Glenea cantor（Cerambycidae：Lamiinae）的触角超微结构的观察。

用扫描电子显微镜研究了Glenea cantor Fabricius触角感觉的外部形态和分布。G. cantor的触角被观察到的是丝状的，由花,、花梗和鞭毛（九鞭毛）组成。观察到四种不同类型的感觉感受器，包括感觉性感觉毛，感觉性毛线虫，感觉性基础毛发和伯姆猪鬃。在触角上发现了3种形态的Sensilla chaetica亚型，并且把Trichodea的Sensilla也分为3种形态亚型。感性基础鞭毛虫被分为两个形态亚型，在鞭毛的亚节F2-F9中被发现，伯姆刚毛仅在花and和头部之间以及花scape和花梗之间的节间关节处被发现。男性和女性成年人的触角在形状，长度和直径上相似。但是，长度，直径，分布 男性中四种不同类型的感官的数量与女性明显不同。描述了这些感觉器的类型，长度，直径，数量和分布，并讨论了它们的可能功能。结果表明，触角段的基部和末端具有相似的感觉密度，但是中间部分的传感器密度明显更高，尤其是对于嗅觉和味觉感官，这可能是因为关节更多地参与了机械感测。传感器的密度与其传感功能密切相关。因此，未来关于嗅觉和性交生物学的研究 并讨论了其可能的功能。结果表明，触角段的基部和末端具有相似的感觉密度，但是中间部分的传感器密度明显更高，尤其是对于嗅觉和味觉感官，这可能是因为关节更多地参与了机械感测。传感器的密度与其传感功能密切相关。因此，关于嗅觉和性交生物学的未来研究 并讨论了其可能的功能。结果表明，触角段的基部和末端具有相似的感觉密度，但是中间部分的传感器密度明显更高，尤其是对于嗅觉和味觉感官，这可能是因为关节更多地参与了机械感测。传感器的密度与其传感功能密切相关。因此，未来关于嗅觉和性交生物学的研究这些观察将有助于G. cantor。
