3种蛾类雄性内生殖系统形态学研究

为了探究蛾类昆虫新的有效分类特征，本研究对直脉青尺蛾Geometra valida、白雪灯蛾Chionarctia niveus和多斑豹蠹蛾Zeuzera multistrigata雄性内生殖系统进行了解剖观察和形态学比较。结果表明：3种蛾类雄性内生殖系统均由精巢、贮精囊（前贮精囊和后贮精囊）、输精管、复射精管、单射精管（单射精管原节和单射精管表皮节）和附腺组成；种间形态差异表现在贮精囊的形状及连接方式、复射精管的形状及长短、单射精管和附腺的长度等方面，这些鉴别特征可为蛾类分类及系统发育研究提供形态学借鉴。

Morphological structure of the male internal reproductive system of three moths species

In order to investigate new effective classification features of moths, this study conducts anatomical observation and morphological comparison on the male reproductive system of Geometra valida, Chionarctia niveus, and Zeuzera multistrigata. The results show that the male internal reproductive system of the three moths consisted of the testes, seminal vesicle (anterior seminal vesicle and posterior seminal vesicle), vas deferens, ductus ejaculatorius duplex, ductus ejaculatorius simplex (the primary segment of the ductus ejaculatorius simplex and the cuticular segment of the ejaculatorius simplex) and accessory gland. The morphological differences among species are reflected in the shape and connection type of the seminal vesicle, the shape and length of the compound ejaculatory duct, the length of the single ejaculatory duct and the accessory gland. These identification characteristics can provide morphological data for research of taxonomy and phylogenetics of moths.
