云南省蚊类的生物多样性特征

The characteristic of mosquito biodiversity in Yunnan province

目的掌握云南省蚊类的属、种及其生物多样性,了解蚊类的地理区划、生态习性及与疾病的关系,为生物生态学研究及蚊媒传染病的防治研究提供技术资料。方法采用重点普查与抽样调查相结合的方法,自1979年以来,先后在全省12个州(市)45个县境内的不同纬度、不同海拔、不同植被地区进行全面系统的蚊类标本采集,以及与其相关的生态生物学调查。结果在长期的调查采集中,采获大量的蚊类标本,获得丰富的生态生物学资料,所获标本,经整理鉴定,发现云南省蚊类为3亚科21属32亚属299种,其中新种53种,中国新纪录28种。结论云南省蚊类属、种繁多,生态习性复杂,在地理区划、生态生物学以及形态特征等方面,表现出明显的生物多样性。

Objective To know the species,families of mosquitoes and their biodiversity,geographic division,ecological habits and relationship with mosquito-borne diseases in Yunnan province for providing technical information for the prevention and control of mosquito-borne diseases.Methods Since 1979,mosquito samples and the data on their ecological and biological characteristics were collected from different latitudes,altitudes and vegetations in 45 counties of 12 prefectures by way of the overall survey combined with the sampling survey.Results A large number of mosquito samples and a great deal of their biological information were obtained.It was identified from the samples that there were a total of 299 species,32 subgernera,and 21 gerera in 3 subfamilies,of which 53 species were of new ones newly identified in the world and 28 species were recorded for the first time in China.Conclusion Mosquito species and genera in Yunnan were of great variety,complicate biological habits,and significant biodiversity revealed in terms of their geographic division,biological behaviors and morphological characteristics.
