星天牛属雄性外生殖器的分类研究(鞘翅目:天牛科)

星天牛属Anoplophora Hope建立于1839年,以A.stanleyana Hope为属模种,1943年Breuning将Cyriocrates Thomson降为一个亚属并入该属,其中指名亚属包括30种,Cyriocrates属包括3种,亚属地位未定的有5种,共38种。属间的区别按指名亚属中胸腹板突片瘤突不很显著,倾斜或垂直位;Cyriocrates中胸腹板突片瘤突显著,向前突出。1951年Gressitt记录我国星天牛21种,至1981年已增加到26个种和亚种。     

楔天牛属7种雄性外生殖器特征比较研究

本文研究了检疫截获的楔天牛属7种楔天牛八点楔天牛、白桦楔天牛、斑点楔天牛、柳楔天牛、青杨楔天牛、山杨楔天牛、十星楔天牛雄性外生殖器的形态结构,并提供其解剖图。研究表明,楔天牛属雄性外生殖器由阳茎基、中茎和内囊3部分组成。阳茎基的阳基侧突具有相对遗传稳定性,且在属内均成近似矩形,并首次测量了7种楔天牛的成虫雄性外生殖器阳基侧突的长宽比。得出了雄性外生殖器形态特征在楔天牛属种内差异小、种间差异大,并能用雄性外生殖器特征有效区分楔天牛属近似种的结论。

桑天牛雄性附腺内容物组分分析

测定桑天牛Apriona germaric(Hope)雄性附腺内容物中各组分含量及变化情况。结果表明,内容物中可溶性蛋白占总腺管鲜重的8.39%;总糖占总鲜重的4.21%;海藻糖和游离氨基酸分别占总鲜重的0.50%、0.25%。随虫龄的增大,内容物中各组分含量不断降低。交配过程中,雄性附腺内容物部分转移到雌虫,交配后附腺内容物中总糖、海藻糖、游离氨基酸等组分含量均降低,蛋白质组分含量先升高再降低,48h即恢复可到交配前水平。大、小附腺内各组分含量变化有差异。     

金绒花天牛与金丝花天牛的鉴定及分布(鞘翅目,天牛科,花天牛亚科,花天牛族)(英文)

金丝花天牛Leptura aurosericans Fairmaire,1895广泛分布在中国南方与东南亚地区,而金绒花天牛Leptura auratopilosa(Matsushita,1931)仅分布于台湾岛。最近10年,国内在金绒花天牛与金丝花天牛的鉴定及分布记录方面出现了一些不一致的报道。为了澄清这些问题,在核对模式标本及检视系列标本(包括许多正在自然交配的成对标本)的基础上,重新描述了这两个种的形态特征,给出了这两个种的鉴别特征并提供了彩色照片,认为金绒花天牛是台湾特有种,目前在大陆尚未发现。

The adipokinetic hormone family in Chrysomeloidea: structural and functional considerations

The presented work is a hybrid of an overview and an original research paper on peptides belonging to the adipokinetic hormone (AKH) family that are present in the corpora cardiaca of Chrysomeloidea. First, we introduce the AKH/red pigment-concentrating hormone (RPCH) peptide family. Second, we collate the available primary sequence data on AKH peptides in Cerambycidae and Chrysomelidae, and we present new sequencing data (from previously unstudied species) obtained by liquid-chromatography coupled with ion trap electrospray ionisation mass spectrometry. Our expanded data set encompasses the primary structure of AKHs from seven species of Cerambycidae and three species of Chrysomelidae. All of these species synthesise the octapeptide code-named Peram-CAH-I (pGlu-Val-Asn-Phe-Ser-Pro-Asn-Trp amide). Whereas this is the sole AKH peptide in Cerambycidae, Chrysomelidae demonstrate a probable event of AKH gene duplication, thereby giving rise to an additional AKH. This second AKH peptide may be either Emppe-AKH (pGlu-Val-Asn-Phe-Thr-Pro-Asn-Trp amide) or Peram-CAH-II (pGlu-Leu-Thr-Phe-Thr-Pro-Asn-Trp amide). The peptide distribution and structural data suggest that both families are closely related and that Peram-CAH-I is the ancestral peptide. We hypothesise on the molecular evolution of Emppe-AKH and Peram-CAH-II from the ancestral peptide due to nonsynonymous missense single nucleotide polymorphism in the nucleotide coding sequence of prepro-AKH. Finally, we review the biological significance of the AKH peptides as hyperprolinaemic hormones in Chrysomeloidea, i.e. they cause an increase in the circulating concentration of proline. The mobilisation of proline has been demonstrated during flight in both cerambycid and chrysomelid beetles.     

Phylogenetic and Functional Implications of the Rhabdom Patterns in the Eyes of Chrysomeloidea (Coleoptera)

Ultrastructural data from 108 species of Chrysomeloidea show that all rhabdom-patterns can be assigned to one of two basic patterns. The insula-pattern: two central rhabdomeres (Rh 7/8) are spatially isolated from the six peripheral ones (Rh 1–6). The ponticulus-pattern: Rh 7/8 fuse at two sites with the ring of Rh 1–6. The distance between the two systems may prevent optical or electrical coupling in the insula-p. The structure of the ponticulus-p may allow electrical coupling as well as contrast-intensifying lateral filtering. Potential relative polarization and absolute sensitivities differ interspecifically between homologous cells and intraspecifically between Rh7/8 and Rh 1–6, and between Rh 7 and Rh 8. The Bruchidae show only the insula-p, the Chrysomelidae and Cerambycidae both. The distribution of the two patterns is subfamily-specific within the Chrysomelidae, but not in the Cerambycidae. Identical patterns must have developed convergently within the Chrysomeloidea. Both basic patterns are subdivided in different subfamilies or tribes.     

Higher‐level phylogeny of longhorn beetles (Coleoptera: Chrysomeloidea) inferred from mitochondrial genomes

Cerambycidae (longhorn beetles) and related families in the superfamily Chrysomeloidea are important components of forest ecosystems and play a key role in nutrient cycling and pollination. Using full mitochondrial genomes and dense taxon sampling, the phylogeny of Chrysomeloidea with a focus on Cerambycidae and allied families was explored. We used 151 mitochondrial genomes (75 newly sequenced) covering all families and 29 subfamilies of Chrysomeloidea. Our results reveal that (i) Chrysomelidae (leaf beetles) are sister to all other chrysomeloid families; (ii) Cerambycidae sensu stricto (s. s.) is polyphyletic due to the inclusion of other families that split Cerambycidae into a ‘lamiine’ clade comprising Lepturinae sensu lato (s. l.) + (Lamiinae + Spondylidinae) and a ‘cerambycine’ clade comprising Dorcasominae + (Cerambycinae + Prioninae s. l.); (iii) the subfamilies within the two clades of Cerambycidae s. s. were monophyletic, except for the placement of Necydalinae nested in Lepturinae, and the placement of Parandrinae within Prioninae (now considered as tribes Necydalini and Parandrini, respectively); (iv) smaller families were grouped into two major clades: one composed of Disteniidae+Vesperidae and the other composed of Orsodacnidae + (Megalopodidae + Oxypeltidae); (v) relationships among the four major clades were poorly supported but were resolved as ((cerambycines + (Disteniidae + Vesperidae) + Orsodacnidae + (Megalopodidae + Oxypeltidae)) + lamiines. Divergence time analyses estimated that Chrysomeloidea originated ca. 154.1 Mya during the late Jurassic, and most subfamilies of Cerambycidae originated much earlier than subfamilies of Chrysomelidae. The diversification of families within Chrysomeloidea was largely coincident with the radiation of angiosperms during the Early Cretaceous.     

Differences in genitalia structure and function between subfamilies of longhorn beetles (Coleoptera: Cerambycidae)

Beetle genitalia are usually described only for taxonomic purposes without considering the possible function of structures. Exceptions are sporadic detailed studies on single species. We studied genital structures in the subfamilies of Cerambycidae and outlined assumptions on the function of these structures and the implications for the phylogeny of the Cerambycidae. We found that male genitalia in particular are taxon-specific on a higher taxonomic level; e.g., the parameres are widely variable in Cerambycinae, while in most Lamiinae species they appear relatively uniform and differ from those of the Cerambycinae. Internal sac structures are very different among the various subfamilies. Small backwards-pointing spines are the most common armature of the internal sac. The female genitalia are less variable, although ovipositor morphology may differ among subfamilies. In most species, the connection between the mates during copulation is achieved by the long internal sac and the ovipositor only, whereas the median lobe and parameres are in contact with the female abdomen only at the beginning of copulation. Cerambycinae and Lepturinae have a basal swelling of the endophallus to prevent it from sliding back into the male abdomen during copulation. The long internal sac functions in connecting the mates and guaranteeing the sperm transfer.

Phylogenetic significance of the ventral nerve cord in the Chrysomeloidea (coleptera: Phytophaga)

Abstract The ventral nerve cord of adult Chrysomeloidea exhibits variation in the degree of fusion of the meso-and metathoracic ganglia. similar variation occurs also in the ganglia ofthe abdominal chain, and in the single or double connectives between them. In adult Chrysomeloidea (and Curculionoidea) there never seem to be more than five separate abdominalganglia, the first two being more or less fused to the metathoracic ganglion and the lasttwo more or lessconnate; the supposed primitive condition is retained in some Cerambycidae. Trends toward the fusion of aditional abdominal ganglia appear in several differentlines in Chrysomelidae (and in Cerambycidae), and in more than one line a conditiones is reached in which only the ganglion in the third abdominal segmetn remains free. Structures possibly representing 'perisynmpathetic organs' have been observed in a few of the seventy-eight European and Indian species studied. systematic and phylogenetic conclusions are drawwn.
