对槟榔红脉穗螟(Tirathaba rufivena Walker)卵及成虫触角的外部形态结构进行扫描电镜观察。卵壳上的受精孔区结构和卵纹分布特征:卵的长径0.65～0.70毫米,短径0.45～0.50毫米;卵纹多数为四边形或五边形;受精孔区的花饰由15～16个小叶组成,小叶长约25～35毫米。成虫触角外部结构特征:触角由柄节、梗节和38～44个鞭节组成;触角背面被鳞片覆盖,绝大部分触角感器位于触角的腹面和侧面;所有鞭节的表皮上都有连续的网状结构,柄节和梗节的表皮上则无网状结构。在雌雄蛾的触角上都可以找到耳形感器、毛形感器、栓锥形感器、腔锥感器、锥形感器(即Bohm氏鬃毛)、刺形感器和鳞形惑器等7种感器。毛形感器数目最多,并根据其形状和表面细微结构分为A型和B型两类。耳形感器根据其形态也可分为A型和B型两类。除锥形感器外,所有感器都分布在触鞭节的网纹区上。本文对此昆虫雌雄成虫触角的差异进行了详细的讨论。
Scanning electron microscopy (SEM) observations of the external morphology of the antennae of eggs and adult adults of the red-bellied borer, Fertilization hole on the egg shell structure and distribution characteristics of the egg: egg long diameter 0.65 ~ 0.70 mm, short diameter 0.45 ~ 0.50 mm; egg most of the quadrilateral or pentagon; flower hole perforated area from 15 to 16 Leaflet composition, leaflets about 25 ~ 35 mm. Adult antennae external structure features: antennae stems, stems and 38 ~ 44 whip node; antennae on the back was covered by scales, the vast majority of antennae in the antennae and lateral ventral; all the whip on the epidermis are continuous Of the mesh structure, stem and stem section of the epidermis is no network structure. Ear-shaped sensors, hair-shaped sensors, plug-in tapered sensors, luminal sensors, pyramidal sensors (ie, Bohm’s bristles), thimble sensors, and scales can be found on the antennae of both sexes 7 kinds of sensors and other devices. The largest number of hair-shaped sensors, and according to their shape and surface structure is divided into two types of A and B type. Ear-shaped sensors according to their morphology can be divided into two types of A and B type. With the exception of the tapered sensor, all sensors are located on the textured area of the whip. In this paper, the differences between antennae of male and female insects were discussed in detail.
