【摘要】 根据云南省不同地理方位、地形地貌、气候与生态等特点,于2001-2009年选取19县(市)为调查点,诱捕小兽,收集其耳廓和外耳道的全部恙螨,分析小板纤恙螨(Leptotrombidium scutellare)在不同宿主、不同地区的分布情况。结果 ,在捕获的4目7科18属30种9 838只小兽体表采集到小板纤恙螨16 491只,占所有恙螨的17.73%(16 491/92 990)。在调查的19县(市)中,12个县(市)有小板纤恙螨分布,主要分布于云南西北部和南部的高海拔、低气温、低降水量地区。小板纤恙螨寄生宿主广泛,主要宿主为大绒鼠(Eothenomys miletus)和齐氏姬鼠(Apodemuschevrieri)。更多还原

【Abstract】 In order to investigate the area distribution and host selection of Leptotrombidium scutellare in Yunnan Province,a field survey was carried out during 2001 to 2009,based on different geographic location,topography,climate and ecological characteristics.A total of 16 491 L.scutellare were captured from the body surface of 9 838 small mammal hosts of 7 families,18 genera,and 30 species in 4 orders,accounted for 17.73%(16 491/92 990) of all chigger mites collected.L.scutellare distributed in 12 counties,more in the northwest and south of the Province.Although L.scutellare could parasitize on different small mammal species,most of them were on Eothenomys miletus and Apodemus chevrieri.更多还原
