摘要：1986年－1988年对昆明按蚊（Anopheles Kunmingensis Dong et Wang.）在云南的地理分布、生态习性、传疟作用等进行了研究。从地理分布、种群数量、嗜血习性、栖息习性、季节消长、自然感染率以及防治试验证实，昆明按蚊是云南省北纬24°以北，海拨1600米以上地区的重要传疟媒介。用常规的化学杀虫剂滞留喷洒，可有效地控制该蚊的密度及有关疟疾流行病学指数。

ABSTRACT.  A. kunningensis was described by Dong and Wang in 1985. During the period 1986-1988，a series of studies were carried out to clarify its goographical distribution，ecology and habits，role in malaria tranamission as well as measures to control it. The results showed tlat A. kunmingensis was the main malaria mosquitoes of which it occurrod to the north of  24°N latitude with an elevation above 1600m.Rice paddies，ponds and ditches were the chief habitats of larvae. Resting places of imagoes were frepuently inside houses，amounting to 81.1％ of the total of house-resting Anopheles. In Novombcr to the first ten-day period of January every year，and no more occurrod below 1600m. By the use of preeipitin tests，the origin of ingested blood in the stomach of house-resting A. kunmingensis was 75.6% indicative of human origin.The seasonal fluctuation of the density of the species was in agreement with the malaria incidence curve of the locality surveyed. This species was sensitivc to P.vivax，natural sporozoite rate of 0.104％. From the above-mentioned studies the writers come to conclusion that A. kunmingensis is an important vector above 1600m. Conventional residual spray of insecticides is effective in control of  this vector.

Key words.  Anopheles kunmingensis，Role in malaria transmission，Ecology.
