【摘要】 牡蛎蚧亚科Lepidosaphinae系半翅目Hemiptera盾蚧科Diaspididae,其中大多数种类是农作物、森林植物、果树、绿化观赏植物和花卉上的重要害虫。盾蚧作为一类重要的检疫害虫已引起人们的极大关注。因此,开展此类昆虫的分类研究有着重要的经济意义。本文对中国牡蛎蚧亚科做了系统的分类研究,主要研究内容包括以下几个方面:首先介绍了世界及中国盾蚧科的研究概况;分析了中国盾蚧科在分类上存在的问题;评述了各分类特征在牡蛎蚧亚科分类研究中的地位及价值,然后介绍了牡蛎蚧亚科的介壳形态、一龄若虫、二龄雌若虫、二龄雄若虫和雌成虫的外部形态特征,同时对中国牡蛎蚧亚科的地理分布进行了研究,结果表明,牡蛎蚧亚科绝大多数种类分布于东洋界,在中国记录的8个属中6个属是东洋界特有属,并且进一步明确该亚科大部分类群分布在华中区和华南区,仅1个属分布在西南区。分类研究记述了中国牡蛎蚧亚科8属78种,其中包括3新种。编制了分属、分种检索表,绘制了新种和部分已知种的重要形态特征图,编制了中国牡蛎蚧亚科名录,对种内变异和运用多特征进行形态分类的问题进行了讨论。本研究建立的新分类单元如下:新种:浙江牡蛎蚧Lepidosaphes zhejiangensis, sp. n.西藏牡蛎蚧Lepidosaphes xizangensis, sp. n.油杉安蛎蚧Andaspis keteleeriae, sp. n.所有新种模式标本及研究标本分别保存在西北农林科技大学昆虫博物馆、中国科学院上海植物生理生态研究所。更多还原

【Abstract】 The subfamily of Lepidosaphinae is Hemiptera, Diaspididae. Most of them can harm agricultural and forestry plants, fruit trees, flowers. Diaspididae as a kind of important quarantine pests has been of great concern. Therefore, studying the taxonomy has important economic significance.The present thesis is a taxonomic study on the subfamily Lepidosaphinae from China. It comprises the following parts:Firstly, the history on the taxonomy of Lepidosaphinae is reviewed in both worldwide and China, analyzed the purpose problem on the taxonomy of Diaspididae; introduced the morphology character, name and the character situation and value, Secondly, introduced the scale shape, first instar, second instar female, second instar male and adult male character in morphology. Then, the distribution of Lepidosaphinae from China is summed up. The results show, most of Chinese genera and species are mainly distributed in Oriental Region, about 6 genera are special genera in 8 Chinese genera. Most of them are distributed in Huazhong and Huanan Region, only 1 genus is distributed in Xi’nan Region.In the part of taxonomy, 8 genera and 78 species from China are recorded, of which 3 new species to science are proposed. The keys are given to all genera and species concerned. Figures with detailed characters are attached for the new species and some certain species. The problem of morphological variations and more characters for taxonomy are discussed. At the end of the paper, checklist of Chinese Lepidosaphinae is attached.The new species are listed as follows: New species: Lepidosaphes zhejiangensis, sp.n. Lepidosaphes xizangensis, sp.n. Andaspis keteleeriae, sp.n.All the type specimens of new species are deposited in the Entomological Museum, Northwest Agricultural & Forestry University, Yangling, Shaanxi, China and Shanghai Institute of Plant Physiology and Ecology, Chinese Academy of Sciences respectively.更多还原
