Therefore, it is necessary to understand the relationship between carabid beetles and nvironment, and further explore the technique of carabid beetles as bioindicators, which might be applied to monitoring and evaluation of environment.

因此，深入研究步甲与环境的相互关系，在此基础上进一步研究其指示作用并应用于生态环境监测和评估之中十分重要。

There has been a lot of researches on carabid beetles as bioindicator in the world, focused on the sustainable management of ecosystem and environmental quality assessment. In China the studies on carabid beetles were mainly focused on taxonomy, faunology and the community diversity, few reports about carabid beetles as bioindicators.

目前国外关于步甲作为指示生物的研究很多，内容主要集中在探索生态系统的可持续管理和对整体环境质量的评估，而国内关于步甲的研究主要是区系分类和群落多样性研究，很少关于步甲对环境的指示作用报道。

Any of numerous beetles of the family Elateridae, which includes the click beetles.

叩头虫叩头虫科的一种甲虫，包括叩头虫

Analysis of the obtained genome amplification showed that DNA after PCR presented obvious polymorphism, and the results were the same using the same primer to amplify the larva and imago of the same species. It indicates that RAPD technique can be applied to the identification of dry samples and dipped larva sample of longicorn beetles as well as the research of phylogeny. These three methods for extracting genome DNA from different species of longicorn beetles at different preserved time are feasible.

对所获得的基因组扩增分析表明，经过PCR之后的DNA能呈现明显的多态性，同种天牛用同一引物扩增幼虫和成虫所获得的结果相同，可以认为，RAPD技术可以应用于天牛成虫干标本及幼虫浸渍标本的鉴定及系统发育研究中，也证明了这3种方法用于提取不同保存时间、不同种天牛基因组的DNA是切实可行的。

Mushroom bodies and antennal lobes in Oxycetonia jucunda were conspicuous. Calyces and lobes of the mushroom bodies.were much developed. In contrast, calyces of Ambrostoma quadriimpressum and Henosepilachna vigintioctomaculata were extremely undeveloped. However, the postretinal fibres and circumpharyngeal nerves of Ambrostoma quadriimpressum were highly developed. In the three beetles, 5-HT immunoreactivity was present in all neuropils of the brain and the suboesophageal ganglion. The pattern of 5-HT immunoreactivity and the localization of immunoreactive somata which often clustered into groups were similar among these beetles, while the immunoreactivity intensity was distinct, especially in the lamina.

结果显示，分类地位相近的三种甲虫脑结构大小相差悬殊：小青花金龟脑结构相对发达，蕈形体结构显著，具有发达的冠和叶，嗅叶发达；马铃薯瓢虫和榆紫叶甲的冠极度退化，嗅叶相对不发达；但榆紫叶甲具有十分发达的网膜后纤维和围咽神经。5-HT阳性纤维在三种甲虫的所有神经纤维网中几乎都有分布，且反应模式相似，但各神经纤维网特别是神经节层染色强度差异显著。5-HT阳性胞体有成群分布现象，且在三种甲虫脑中的空间分布位置基本一致。

The scarabeid beetles (particularly the subfamilies Coprinae and Aphodinae) include most of what are recognized conventionally as 'dung beetles', and the larger species are especially important contributors to the consumption and disappearance of dung.

金龟类甲虫(特别是金龟子亚科和 Aphodinae)包括大部分一向俗称为「粪金龟」的甲虫，较大型的种类对粪便的消耗和消失尤为重要。

The ecological values of dung beetles were reviewed, including dung transferring to underground, secondary seed dispersers, pollination, biological control, intermediate hosts of parasites, broadly applications, bionic and theory importance. The imminency and signification of dung beetles conservation were proposed.

文章系统介绍蜣螂的生态价值，包括转将运粪便到地下、对种子二次传播的作用、传粉作用、对有害生物的控制作用和寄生虫的中间宿主，以及广阔的开发应用前景、重要仿生学意义和重大理论意义；并进一步提出蜣螂保护的迫切性和重要意义。

Others farmers separate them out, since larvae and beetles might chow on the inert pupal stage, and beetles may eat pupa/eggs.

其他农民它们分开了，因为幼虫和天牛可能对周惰性蛹的阶段，甲虫，可吃蚕蛹/蛋。

The structure and 5-HT immunoreactivity in the brain and suboesophageal ganglion of three beetles, Ambrostoma quadriimpressum, Henosepilachna vigintioctomaculata and Oxycetonia jucunda, were first studied by means of colophony-paraffin embedding serial section technique and strepteavidin-peroxidase immunohistochemical method. The results showed that the brains of these three taxonomically closely related beetles were remarkably different in composition and size.

采用树脂石蜡组织包埋连续切片技术，结合免疫组化链霉菌抗生物素蛋白-过氧化物酶染色法，首次对三种甲虫(榆紫叶甲、小青花金龟、马铃薯瓢虫)的脑进行了详细观察研究，分析了三种甲虫脑组织结构特征，初步构建了三种甲虫脑内5-HT抗原系统免疫组化反应模式。
