革螨

Methods:Wild rodents were captured by snap-traps in three different ecological habitats in the region from June 1998 to May 1999.7 species of rodents,568 individuals were examined for ectoparasites,16 species of flea,3 species of tick,22 species of gamasid mite,and 7 species of chigger mite collected.

1998年6月至1999年5月在该地区的3类生境按常规方法共捕获鼠类7种568只，采集体外寄生虫48种3859只，其中蚤类16种582只，蜱类3种416只，革螨22种1081只，恙螨7种1780只。

Spearman correlation analysis showed that the abundance and species of total ectoparasites, chigger mites, sucking lice, fleas or gamasid mites were not correlated with the body weight of hosts.

Spearman相关分析表明，体表寄生虫、恙螨、吸虱、蚤类和革螨的数量与宿主身体参数之间无相关性。

Methods: By reviewing some related literatures about the relationship between gamasid mites and diseases.

通过查阅大量关于革螨与疾病关系研究的最近几年文献。

The structures of gamasid mite communities are complicated,with high diversity indices.

主要鼠种体外寄生革螨群落结构复杂，生物多样性指数较高。

The niche breadth could be used as an index for evaluating the host specificity of gamasid mites, whose similarity in population distribution was largely related to that of their hosts, as well as their taxonomic distance.

生态位宽度可以作为评价革螨宿主特异性的定量指标，革螨种群分布的相似性与其宿主的相似性程度有着很大的关系，并受其动物分类学远近的影响。

Objective To determine the niche breadth and overlap in eleven dominant species of gamasid mites parasitic on 39 species of small?mammal hosts around Biluoxueshan Mountain in Weixi, Yunnan.

目的 应用现代生态学中生态位的理论和方法，对云南省维西县碧罗雪山周边地带11种医学革螨在39种小兽宿主资源上的生态位宽度和生态位重叠进行研究。

Non-parametric Mann-Whitney U -test showed that there was no significant difference between male and female hosts on the species richness and abundance of total ectoparasites, chigger mites, sucking lice, fleas or gamasid mites.

U 检验表明，体表寄生虫、恙螨、吸虱、蚤类和革螨的数量和物种数在雌雄宿主体表间的差异无统计学意义。

Walchia ewingi Fuller（66.2%）, Laelaps turkestanicus Lange（38.5%）, Paradoxopsyllus custodies Jordan（42.9%）and Hoplopleura pacifica （80.1%）were the most predominant species of chigger mites, gamasid mites, fleas, and sucking lice, respectively.

攸氏无前恙螨为优势恙螨种，占恙螨总数的66.2%(710/1 072)；土尔克厉螨为优势革螨种，占革螨总数的38.5%（396/1 029）；绒鼠怪蚤为优势蚤种，占蚤总数的42.9%（9/21）；太平洋甲胁虱为优势吸虱种，占吸虱总数的80.1%（217/271）。

Results:The values of trophic niche breadth of Frontopsylla nakagawai,Ixodes persulcatus,Laelaps micromydis and Lepotrombidium orientale were the widest in different ectoparasity type.

结果：营养生态位最宽的种类，蚤类是窄板额蚤，蜱类是全沟硬蜱，革螨是巢鼠厉螨，恙螨是东方纤恙螨。

Methods: The titres of HFRSV in gasmid mite were dynamic observed from cultured cells.

用直接细胞培养动态观察革螨体内HFRSV滴度。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
