昆虫种类繁多,它与生态系统中的生物多样性,以及人类的日常生活和生产密切相关。自2000年黑腹果蝇Drosophila melanogaster全基因组测序完成以来,至今已先后开展了88种昆虫全基因组测序工作,这标志着昆虫学研究进入了基因组时代。本文综述了近年来昆虫基因组测序进展,以及基于基因组的昆虫学研究方法及应用等两方面的研究成果。同时,着重介绍了昆虫全基因组测序进程,昆虫基因组在个体生物学、多物种间及种群,及系统生物学研究中的应用等方面的内容。最后,还探讨了基因组时代昆虫学研究所面临的挑战。 相似文献

中国昆虫生理学三十年 总被引:1,自引:0,他引:1
昆虫生理学,是昆虫学中的一门基础学科,是现代实验昆虫学的一个重要组成部分。解放以前,我国的这一研究领域几乎是空白;三十年来我国昆虫学工作者在党的领导下从无到有,创立了有关的研究单位,培养了研究人材。在几次全国科学技术发展规划中列入了有关的科研项目,促使本门学科的发展。 相似文献

重组DNA技术即基因工程,亦为人们称做基因克隆或基因操作。重组DNA技术已被应用于昆虫学的基础研究和应用研究中。本文首先对重组DNA技术及基因转移技术(在昆虫学研究中与重组DNA技术配合应用的重要手段)作一简述,然后着重介绍这些技术在昆虫学研究中的应用概况。 重组DNA技术 重组DNA技术就是将DNA从细胞中分离出来,切割成片段,与载体DNA连接,形成重组DNA分子,然后导入宿主细胞,进行复制。 相似文献

<正>昆虫学是以昆虫为研究对象的科学。传统上,将昆虫学分为普通昆虫学和应用昆虫学二大类。其实,普通昆虫学是应用昆虫学的基础和源泉,应用昆虫学是普通昆虫学的发展与应用,也是人类研究昆虫的目的所在,二者紧密联系,难以分割。本刊所述的《应用昆虫学》,就是一门基于昆 相似文献

昆虫学(Entomology)是研究昆虫之科学。昆虫学分基础昆虫学和应用昆虫学。昆虫学情报源主要集中在专业期刊上,据英国文献情报专家帕米拉·吉尔伯特(Pamel Gilbert)的统计,全世界有259种学术期刊(含相关、交叉学科的期刊)构成了昆虫学期刊情报源,但常用仅在一百种内。为帮助科研人员更好更快地检索昆虫学文献,笔者特将中科院上海昆虫研究所 相似文献

文中首次报道了缅甸琥珀中的长扁甲Mallecupes qingqingae Jarzembowski, Wang and Zheng, 2017的阳茎化石, 并讨论了该器官的古昆虫学和现生昆虫学意义。甲虫在现生生物中的多样性最高, 而它们的生殖器则在甲虫系统分类中的应用已经超过百年历史。这些小而精美的器官通常很难保存在化石里, 但文中特异保存在中生代琥珀中的生殖器则为原鞘亚目甲虫的分类学研究提供了新的启示。 相似文献

Abstract The MX International Congress of Entomology was hosted by China in Beijing, June 28 to July 4, 1992. Because of the strong support of the Chinese government and the enthusiastic cooperation of the entire Chinese entomological community, the congress attracted more participants from more countries than ever before. This report compares the relative strength of Chinese entomological research programs with that of the outside world, the relative strength of different areas of China itself, and the hierarchy, multitude and diversity of institutions involved to varying extent in entomological programs. 相似文献

For over two decades, near-infrared spectroscopy (NIRS) has been applied to a wide spectrum of problems in the field of insect taxonomy. It provides a rapid, non-destructive and relatively cheap method of metabolomic profiling, which can often be used to discriminate closely related species in the same genus. Furthermore, very little training or entomological knowledge is required to operate the instrument. However, a taxonomist is still required to ensure accurate identification of samples used for NIRS model creation and validation. To date, most research has focused on species of economic or epidemiological importance, such as mosquitoes, flies or stored product pests. However, an increasing number of studies are applying NIRS for entomological research with a purely “academic” purpose. As research continues in this field, NIRS has the potential to become more widely accepted in entomology, allowing for the rapid metabolomic profiling of thousands of species. 相似文献

Pinned insect specimens stored in museum collections are a fragile and valuable resource for entomological research. As such, they are usually kept away from viewing by the public and hard to access by experts. Here we present a method for mass imaging insect specimens, using GigaPan technology to achieve highly explorable, many-megapixel panoramas of insect museum drawers. We discuss the advantages and limitations of the system, and describe future avenues of collections research using this technology. 相似文献

Following attack on an insect vector-perhaps with insecticide or by removing breeding sites-we need to know what reduction in disease can be expected. In general, reliable predictions of the epidemiological consequences of any entomological change are highly desirable. Such predictions require a measure of the capacity of an insect population to transmit disease. A popular approach is to try to quantify all the entomological components of transmission, in isolation from the parasitological components, and then calculate the maximum daily reproductive rate of the disease-known as the Vectorial Capacity. But to measure accurately all the entomological components is technically demanding. In this article, Chris Dye argues that epidemiological predictions could be made by including only the dominant entomological variables in an index-a streamlined Vertical Capacity-which can then be fine-tuned by closely matching entomological and parasitological observations. 相似文献
