滇西地区三种卵翅蝗虫雄性外生殖器形态解剖

首次描述了三种卵翅蝗 :方板卵翅蝗CaryandaquadrataBietXia、大尾卵片翅蝗C.macrofrculaMaoetOu和德宏卵翅蝗C.dehkngensisMaoetal的雄性外生殖器。结果显示其结构组成相同 :阳茎基背片均无桥 ,后突较长 ,侧板狭长 ,这些特征提示它们有较近的亲缘关系。但阳茎基背片在前突、侧板、冠突、后突和阳具复合体的基瓣形态差异明显 ,可作为分类上的依据。     

斑翅蝗科六种蝗虫雄性外生殖器的形态研究

利用显微观察并描述了斑翅蝗科六种蝗虫雄性外生殖器的形态特征。结果表明：六种蝗虫雄性外生殖器发生变化最为明显的部位是冠突、前突、后突、桥及色带基支和色带拱，在种问存在明显差异。通过对雄性外生殖器的形态结构比较。在探讨蝗总科分类和系统发育上均具有重要意义。     

澳大利亚及斯洛文尼亚稻绿蝽(Nezara viridula)外生殖器微细结构电镜观察

澳大利亚和斯洛文尼亚的稻绿蝽因不完全的生殖隔离而曾被认为是两个不同的但互为姊妹的种群 .作者对采自于澳大利亚和斯洛文尼亚的稻绿蝽的雄性、雌性外生殖器及触角节上的感觉毛进行了解剖比较和扫描电子显微镜下的观察研究 ,旨在从外生殖器及触角感觉器等方面找出支持该观点的证据 .研究证明 ,上述几种器官的微细结构在两个种群间并无显著的差异 ,不存在将二者分为姊妹种的依据 .故两个群体间生殖隔离现象与外生殖器的结构无关 .     

The occurrence and function of the sphragis in the zerynthiine genera Zerynthia,Allancastria and Bhutanitis (Lepidoptera: Papilionoidea: Papilionidae)

In some butterfly species males attach a large external mating plug termed a sphragis to the female abdomen during mating. This is derived from male accessory secretions and covers the female ostium bursae and surrounding areas, thus preventing or delaying remating. Specimens of all 12 species of the genera Zerynthia, Allancastria and Bhutanitis (Lepidoptera: papilionidae), which form a natural clade within the Zerynthiini, were examined for presence or absence of a sphragis and their male and female genitalia were studied. In all three genera female genitalia lack a typical sinus vaginalis and the sterigma is modified to form an exposed, shiny, well-sclerotized genital plate, derived from the fusion and expansion of the lamellae ante- and postvaginales. The exposed ostium bursae is situated near the posterior end of the genital plate in Zerynthia, whereas in Allancastria and Bhutanitis it is near the anterior end. A crude irregularly formed sphragis was found at least facultatively in all species. The sphragides of Zerynthia and Bhutanitis were generally poorly developed, in most cases only partially covering the female genital plate. In Allancastria the sphragis mostly covered the genital plate entirely, and generally incorporated numerous long scales derived from the male’s 8th abdominal segment; scales were sometimes sparse or absent, probably due to depletion from repeated matings by males. In Zerynthia, males lacked the dense terminal abdominal tuft of elongated scales found in Allancastria, and their sphragis lacked scales. The sphragis of Bhutanitis thaidina incorporated scales from the male valves, whereas in the B. lidderdalii sphragis (and probably B. ludlowi) the scales derived from the male’s 8th abdominal segment. The role of the scales and possible reasons for the difference in the development of the sphragis among these genera are discussed.     

A new shield-bug species Piezodorus grossi (Het.: Pentatomidae) from the Australasian region previously confused with P. hybneri (Gmelin)

Material previously identified as Piezodorus hybneri (Gmelin) from the Australasian region is here described as a new species, P. grossi sp. nov. The two species can be distinguished on the basis of the aedeagus in the male and spermathecal proximal duct in the female.     

雏蝗属五种蝗虫雄性外生殖器的比较(直翅目:网翅蝗科)

利用显微观察并描述了直翅目网翅蝗科雏蝗属青藏雏蝗Chorthippus qingzangensis、小翅雏蝗C．fallax、东方雏蝗C．intermedius、红胫雏蝗C．rufitibis、白纹雏蝗C．albonemus共五种雏蝗雄性外生殖器的形态特征。结果表明：五种雏蝗雄性外生殖器发生变化最为明显的部位是冠突、前突、侧板、桥和色带连片及阳茎基瓣，在种间存在明显差异。通过对雄性外生殖器的形态结构比较，在探讨蝗总科分类和系统发育上均具有重要意义，并为雏蝗属种类鉴定提供了新的分类依据。     

内蒙古小网蝽外生殖器特征及国内新纪录(半翅目;异翅亚目;网蝽科)

作者重新整理了内蒙古小网蝽属昆虫标本,并对雄虫外生殖器及雌虫第一生殖肢进行了解剖观察。在此基础上,对内蒙古小网蝽作了修订,简要描述了两性外生殖器的主要特征,并记述了2中国新纪录种:黑腿小网蝽Agramma femorale Thomson,1871,淡须小网蝽A. abruptifrons Golub, 1989。     

青海省粉蝶科雄性外生殖器的研究

本文通过对青海省东部地区８个属２２种蝴蝶的雄性外生死器之比较，确定了种属特征，对蝴蝶种属检索表的建立有一定的借鉴意义。     

内蒙古网蝽科昆虫外生殖器的解剖研究

对内蒙古网蝽科11属29种网蝽的雄性外生殖器和9属26种的雌性第1生殖肢进行了解剖比较,将其特征列成分种检索表,并描绘出外生殖器各部分的特征图。根据特征,内蒙古网蝽科昆虫的雄性外生殖器分为6个类型。     

青海鳞翅目蝴蝶雄性外生殖器研究

通过对七科蝴蝶的雄性外生殖器进行比较研究，认为雄性外生殖器可以作为蝴蝶分类的主要标准之一。在科的分类阶元水平上，区分的标准主要在于背兜、钩突、侧突及抱握器之上。
