步甲

Darkling beetles do have wings, but can't fly.

步甲确有翅膀，但不能飞。

During 1994～1996,we found that Scarabaeidae,Carabidae and Elateridae are the dominant groups of soil Coleopteran.They showed the obviously seasonal dynamic in density ,vertical distribution and diversity that have different responses to the changes of season. According to their roles in grassland ecosystem, their main functions in the system can be performed by their larvae, and the most powerful influence in the system should be in spring and autumn.

大针茅草原中土壤鞘翅目昆虫的组成以金龟总科、步甲科为主。2）土壤鞘翅目昆虫密度具有明显的季节动态，即春季和秋季密度较高，夏季密度较低。3）土壤鞘翅目昆虫中不同类群对季节的变化有明显不同的响应。4）随季节变化土壤鞘翅目昆虫在土壤中的垂直分布及水平分布有显著变化。

By using the technics of scanning electron microscope, the shape, amount and distribution of the antennal, maxillary and labial palps, urogomphi sensilla of the larva Carabus prodigus were observed and their function were discussed.

摘 要：应用环境扫描电镜对奇步甲幼虫触角、下颚须、下唇须和尾突感器进行观察，对各类感器的数量、长度及分布特点等进行描述，并探讨各类感器的功能。

The individuals of Carabidae were significantly more abundant in NRF than those in the other forests, and significantly sparser in USF than those in the other forests.

其中，步甲科的个体数量在NRF显著多于其他林型，在USF显著少于其他林型

Predatory ladybirds and Carabidae, parasitic wasps, spiders are the dominant species.2. Dynamics of insect pests community.

天敌涉及2纲8目12科，16种，主要是蜘蛛、鞘翅目的捕食性步甲和瓢虫及寄生蜂。2。

It was different in the occurring time and quantity of dominant species: in early spring, there were more Psyllidaes in the dense planted area, but more main pests Opatrums and Scarabeidaes and their nature enemies Carabidaes and Spiders in the low planted area. After autumn, the quantity of Psyllidae was the largest in the low planted area, but the least in the dense planted area.

群落个体数稀植区在大部分时间内均高于其它2区。3个区的主要优势害虫及其天敌在发生时间和数量上有一定差异，早春密植区木虱发生数量较大，稀植区中砂潜、金龟子类害虫以及步甲、蜘蛛类天敌数量相对丰富，入秋后稀植区木虱发生量最大，密植区最小。

The family Tenebrionidae is one of the largest families of insects.

拟步甲科昆虫是分布范围广、种类丰富、生活类型多样的一类甲虫。

More individuals of Tenebrionidae were found in NRF than those in other forests.

拟步甲科在NRF显著多于其他林型

This paper reports the extraction genome DNA from eight species of Tenebrionidae insects including the fresh specimens and the preserved specimens in 100 percent alcohol with methods of SDS-proteinase K and KAC.

对拟步甲科 8种昆虫的新鲜标本及无水乙醇浸泡标本，分别用SDS 蛋白酶K消化法和乙酸钾抽提法进行基因组总DNA的提取。
