摘要: 目的:对以蚊、蠓为主吸血双翅目昆虫进行多样性分析。方法:运用相对稀有种类数(%)、相对极低种类数(%)、种间相遇机率、最优势种、物种数及种群密度等指标,对1987~1988年获取的吸血双翅目昆虫数据进行整理。结果:6种参数基本反映了蚊科昆虫和吸血蠓的多样性分布。在我国北方,种间相遇机率值比较低,优势种突出;而在南方,种间相遇机率值高,最优势种的优势度指数比北方的种类要低。结论:本文分析结果对于吸血双翅目昆虫多样性的进一步研究具有重要意义。

Abstract: The present paper deals with diversity of blood-sucking insects (mosquitoes and biting midges et al) by analysing the data obtained from most parts in China during 1987~1988.All the data were summarized in table 1~3.The results of the present study may be summarized into 2 main points: 1.The probability of interspecific encounter (PIE) index was lower in northern region than in southern region.2.The species numbers in southern region was more than that in northern region, and species′ dominant degree was higher in northern region than in southern region.
