【摘要】 在新疆阿克苏地区,不同景观地带有不同类型的土壤和蛉种组成。在地带性土壤为棕钙土的山地和灌淤土区的古老绿洲,中华白蛉长管亚种分别占91.1％和92.5％,棕漠土区的山麓砾质戈壁,亚历山大白蛉为优势种,占91.5％,而在林灌草甸土区的荒漠,则以硕大白蛉吴氏亚种为多,占60.9％.本文结合以往新疆的蛉种调查资料分析,认为土壤类型是影响白蛉分布的重要因素。白蛉人工感染实验和自然感染调查的结果表明,上述三种白蛉都是阿克苏地区黑热病的媒介,其传病作用则随景观地带的不同而异。更多还原

【Abstract】 In 1984, a sandfly fauna survey in Aksu Region of Xinjiang revealed that the component of sandfly population was different in four landscape zones, where the soils are different. The mountainous area and ancient oasis are covered with brown calcareous soil and whitish oasis soil, where Ph. chinensis longiductus is the predominant species amounting to 91.1% and 92.5% of sandfly population respectively. In the stone desert area at the foot of the mountain covered with brown desert soil, Ph. alexandri was most prevalent, being 91.5%. While in the dry desert area covered with scrubby meadow soil where Populus diversifolia and Tamalix sp grow, Ph. major wui was’ 60.9% and no Ph. chinensis longiductus or Ph. alexandri was found. According to the data of this paper and previous fauna survey made in Xinjiang, the authors suggested that the main factor influencing the geographical distribution of sandflies is the type of soil.Based on the results of the artificial infection of these 3 species of sandflies and natural infection of Ph. alexandri, it was demonstrated that all these sandflies play a role in kala azar transmission in Aksu Region. Different sandfly species play different roles in the transmission of kala azar in different areas.更多还原
