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,海拔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。
A. kunmingensis was described by Dong et Wang in 1985. During the period 1986-1988, a series of studies were carried out (o clarify its geographical distribution, ecology and habits, role in malaria transmission as well as meastures to control it. The results showed that A, kunmingensis was the main malaria mosquitoes of which it occurred to the north of 24° N latitude with an elevation above 1600 m. Rice paddies, ponds and ditches were the chief habitats of larvae. Resting places of imagoes were frequently inside houses, amounting to 81.1% of the total of house-resting Anopheles. In November to the first ten-day period of January every year, and no more occurred below 1600 m. By the use of precipitin 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 inci-dencc curve of the locality surveyed. This species was sensitive to P. vivax, natural sporozoite rate of 0.104%. From the above-mentioned studies the writers come to the conclusion that A. kunmingensis is an important vector in 1600 m. Conventional residual spray of insecticides is effective in control of (his vector.
