摘要
本文报道玉龙蝠蛾 Hepialus yulongensis Liang 触角感觉器种类、形态和分布的扫描电镜观察结果。蝠蛾触角呈丝状,由柄节、梗节和21—27个鞭节组成,总长2.3—2.7毫米,柄节比以后各节长,触角表面缺少隆起的网纹。触角感觉器计有七种,其名称为毛形感器、刺形感器、腔锥感器、锥形感器、鳞形感器、Bohm氏鬃毛及仅出现于雄蛾的钟形感器。根据中心栓的长度,腔下陷的深度和直径,腔锥感器基本上可分为长栓和短栓两种形态类型,腔的周围都无向内倾斜的缘栓;毛形感器可进一步分为A型和B型;Bohm氏鬃毛数量多,主要分布于柄节、梗节,但在端节也能见到。
Scanning electron microscopy of the antennae of the Yulong ghost moths Hepialus yulongensis was observed. The form of the antennae, the sensillar types, and distribution of the various sensilla were examined. The antennae of He plains is filiform with scape, pedicel and 21-27 flagellar segments.The antennae of both sexes are of 2.3-2.7mm length. The scape is longer than the following segments. The cuticle of the antenna lacks the reticulation of raised ridges.
Six types of sensilla found on the antennae of both male and female include sensilla trichodea, sensilla chaetica, sensilla coeloconica, sensilla basico-niea, sensilla squamiformia and Bohm' s bristles. Moreover, sensilla campani-form occur on the antennae of male moths. The sensilla trichodea are further subdivided into two types (designated A and B). Bohm' s bristles occur mainly on the scape, pedicel, and apical segment. The gradual increase in the number of sensillum coeloconicum along the base of flagellar segments and the decrease near the tip. There are two morphological types of the sensilla coeloconica include the center peg of long and short pattern. The sensilla coeloconica of both types lack the inward slanting fringe pegs in the depressed periphery.
