对蒙古高原天牛亚科昆虫种类组成及区系进行初步分析,已记载共26属69种,各属所包含的天牛种类数量差异很大,以Xylotrechus为优势属,Chlorophorus次之,且在俄、蒙、中三国,各属的种类组成、数量也有差异;在种的组成中,以古北种所占比例最大,为60.87%,广布种也占有相当比例为39.13%。Xylotrechus在俄、蒙、中三国均以古北种占优势,而Chlorophorus在蒙古国以古北种占优势,在俄、中两国以广布种占优势。柽柳漠天牛Hesperophanes heydeni Baeckm.为中国新记录种。中国无分布记录的蒙古高原天牛亚科昆虫有4种:戈壁鞍背天牛Asias gobiensis Namhaidorzh、乌布苏虎天牛Chlorophorus ubsanurensis Tsherepanov、蒙瘦尾鞘天牛Leptepania okunevi Shabliovsky、阿木尔脊虎天牛Xylotrechus pantherinus(Sav.)。  相似文献

对2011年6月采自云南勐仑的73头异色跗虎天牛Perissus mutabilis Gahan,1894标本进行研究,发现该种73号标本在鞘翅斑纹、前足爪开式、前胸背板颜色及斑点、后足腿节长度存在不同程度的差异,研究认为上述特征不宜用作该种分类鉴定的特征。红胸跗虎天牛Perissus mutabilis vitabilis Pic,1923和黑胸跗虎天牛Perissus mutabilis obscuricolorPic,1937依据部分上述特征建立,且特征出现交叉,分布区域与指名亚种异色跗虎天牛P.mutabilis mutabilis Gahan,1894重叠,建议取消红胸跗虎天牛P.mutabilis vitabilis Pic,1923和黑胸跗虎天牛P.mutabilis obscuricolor Pic,19372个亚种。并对异色跗虎天牛P.mutabilis Gahan,1894进行重描述。  相似文献

Zorion guttigerum is a flower-visiting longhorned beetle endemic to New Zealand. Sexual selection of this species in relation to the body size and color form of different sexes was investigated in the field. The population sex ratio, based on censuses of feeding and mating sites (flowers), is male-biased. Females are significantly larger than males. Both sexes have antennae of similar length but the antennal length relative to the elytral length is greater in males than in females, and the antennal length of males increases more with an increase in body size than that of females. Both sexes have dark blue (DB) and yellowish-brown (YB) individuals. Both pair-bonded and solitary males are similar in elytral and antennal length. In pair-bonded males, DB individuals are significantly more numerous than YB ones, but in solitary males, the number of both color forms is similar. Males tend to have territory protection behavior, fighting with and chasing away rival males from feeding and mating sites. Larger males usually win the fight but the size-dependent fighting advantage does not translate into mating success. Male color plays an important role in mating success, with DB males having a significantly better chance to mate than YB males. Furthermore, male body size and color also have interactions in mating success: males of DB color morph obtain a greater mating advantage according to body size. Pair-bonded females are significantly larger and have longer antennae than solitary females, suggesting that males prefer larger females for mating. In addition, females of DB color morph with longer antennae are also preferred by males for mating. The significance of these findings is discussed.  相似文献

对分布于北京的10种脊虎天牛属甲虫开展了分类研究,恢复了北京脊虎天牛Xylotrechus pekingensis Pic,1939的地位,不再是宽带脊虎天牛Xylotrechus yanoi Gressitt,1934的异名,报道了本种在河北和陕西的新分布记录.提出双带脊虎天牛Xylotrechus bifenestratus Pic,1916是四带脊虎天牛Xylotrechus polyzonus (Fairmaire,1888)的新异名,两者的模式标本均产自北京.本文还报道了3种北京新记录种:显纹脊虎天牛X.ibex (Gebler,1825)、葡脊虎天牛X.pyrrhoderus Bates,1873和黑胸脊虎天牛X.robusticollis (Pic,1936).通过检视标本,很多新的分布信息被加入到相关的种类.最后本文提供了分布于北京的10种脊虎天牛属甲虫的分种检索表.  相似文献

Longhorn beetles are among the most important groups of invasive forest insects worldwide. In parallel, they represent one of the most well-studied insect groups in terms of chemical ecology. Longhorn beetle aggregation-sex pheromones are commonly used as trap lures for specific and generic surveillance programs at points of entry and may play a key role in determining the success or failure of exotic species establishment. An exotic species might be more likely to establish in a novel habitat if it relies on a pheromone channel that is different to that of native species active at the same time of year and day, allowing for unhindered mate location (i.e., pheromone-free space hypothesis). In this study, we first tested the attractiveness of single pheromone components (i.e., racemic 3-hydroxyhexan-2-one, racemic 3-hydroxyoctan-2-one, and syn-2,3-hexanediol), and their binary and tertiary combinations, to native and exotic longhorn beetle species in Canada and Italy. Second, we exploited trap catches to determine their seasonal flight activity. Third, we used pheromone-baited “timer traps” to determine longhorn beetle daily flight activity. The response to single pheromones and their combinations was mostly species specific but the combination of more than one pheromone component allowed catch of multiple species simultaneously in Italy. The response of the exotic species to pheromone components, coupled with results on seasonal and daily flight activity, provided partial support for the pheromone-free space hypothesis. This study aids in the understanding of longhorn beetle chemical ecology and confirms that pheromones can play a key role in longhorn beetle invasions.  相似文献
