第三部分区系研究取得以下主要成果：1.对影响拟步甲分布的地形、温度和植被因素进行了分析。

The results are mainly as follows : 1 . The landforms , temperature and vegetation are analyzed .

逗斑青步甲捕食黄毛鼠仔鼠研究初报

A Primary Report of the Study of the Ground Beetle ( Chlaenius virgulifer ) Preying on Young Farmland Mouse

生物多样性研究中，动物多样性研究部分以步甲作为指示生物展开，方法为陷阱法；

Carabid beetle was selected as bioindicators and pitfall trapping was used as sampling method for animal biodiversity evaluation ;

边界对相邻农田步甲群落的多样性有积极影响；

Field margins had a positive effect on the diversity and richness of carabid community in their adjacent crop fields .

该区拟步甲区系分类研究虽有一定基础，但缺乏全面系统的总结工作。

Although with some foundation , the taxonomic study on Tenebrionidae from North China region needs a comprehensive and systematic study .

农田边界是生物的避难所和聚集地，对步甲有重要的保护作用，农田边界上的步甲密度普遍比相邻农田中高，月份间步甲数量的波动幅度也较小。

Carabid density in field margins is higher than that in adjacent farmlands , and the monthly fluctuation range there is also narrower .

在三大山系中，天山山系的拟步甲种类最多，为54种，占20.3%；

Tianshan Mountain has most various kinds of the darkling beetles ( 54 species ) amounting to 20.3 percent of the total number ;

步甲数量的季节变动在不同种植模式间不同，并在一定程度上受农田景观及农事活动的影响。

The fluctuation of carabids differs among different crop-planting patterns , and is affected to an extent by the changes of the landscape and agricultural activities .

不同的生境类型下步甲群落的个体数量差异很大，农田生境中步甲群落个体数量都较低，林地和农田边界地带较高；

Great differences of the individual number among habitats were observed that there were much more individuals in woodland and field margin than that in croplands .

结果表明，林地和农田边界类生境相对于农田类生境拥有更多的步甲个体数和物种数；

The results indicated that the numbers of both carabid species and individuals were much higher in the field margin and woodland than in the crop field .

取得如下主要研究成果：1.基本明确了华北动物区拟步甲的组成和区系特点。

Main research results obtained are as follows : 1 . Preliminarily make clear about the component and characteristics of the fauna on Tenebrionidae of North China .

从而说明平均气温和平均降水对拟步甲的发生起到至关重要的作用，降雨量过大是该类昆虫的主要阻碍因素。

The average temperatures and the average precipitation play a crucial role for the occurrence of Tenebrionidae insects . The main Constraints to these beetles is excessive rainfall .

科级水平来看蚁科、步甲科和蛉蟋科数量最多，分别占总数的37.7%、25.5%和19.2%。此三科为数量最丰富的类群。

In the family level , the largest groups were Formicidae , Carabidae and Gryllidae which account for 37.7 % , 25.5 % and 12.9 % of the total .

拟步甲科昆虫形态变化多端，生活类型极富多样，常在荒漠、半荒漠地区形成个体数量较大的群落，与环境之间形成平行进化关系。

Tenebrionidae insects with various morphology and diverse types of life history frequently colonize a larger number of communites , and form a parallel evolutionary relationship with the environments .

内蒙古自治区已知拟步甲由3亚科、20族、44属、158种组成。

The known Inner Mongolia tenebrionid beetles ( Coleoptera : Tenebrionid ae ) are composed of 3 subfamilies , 18 tribes , 44 genera and 158 species up to now .

1996与1997年在河北省曲周县盐渍化改造区，采用陷阱法调查了农田中步甲的物种组成与数量分布。

In 1996 and 1997 , a carabid community and its fluctuation were studied by the pitfall method in the salinity transforming area in Quzhou County , Hebei Province , China .

与中国其他动物地理区相比，该区的拟步甲区系组成总体表现为地域面积较大、分布种类分布较少的趋势。

Compare with other regions , the fauna shows a trend with larger area and fewer species . As a whole , there are more soil darkling beetles than arboreal ones in the North China region .
