腾冲县固东区,位于云南西部地区,1986年曾发生较大面积的疟疾流行,发病率达12%∞.当地按蚊相简单,仅捕获昆明按蚊、中华按蚊和多斑按蚊3种,以昆明按蚊为优势种,捕于人、牛房共14871只按蚊,其中昆明按蚊占77.6％。为弄清当地的传疟媒介及其以传播疟疾有关的生态习性,于1987年7～8月,对昆明按蚊和中华按蚊的传疟作用作了定量研究,并将两种按蚊作一比较。昆明按蚊的昆虫学接种率为0.0038,中华按蚊为0.000031,按比例推算当地居民的疟疾病例,由昆明按蚊传播占99.1％,中华按蚊为0.9%。结果证明:昆明按蚊为当地的高效媒介.它的传疟作用相当于中华按蚊的110倍。
The Gudong area of Tengchong County, located in the western part of Yunnan Province, had a large area of malaria epidemic in 1986 with a incidence rate of 12% ∞. The local mosquito was simple and only caught three species of An. Kunming, An. Sinensis and An. Anopheles, the dominant species of Kunming, captured a total of 14,871 Anopheles mosquitoes, of which 77.6% of Kunming Anopheles. In order to understand the local transmission malaria vector and its ecological habits related to the spread of malaria, from July to August 1987, quantitative studies on the malarial transmission of Anopheles sinensis and Anopheles sinensis were conducted. A comparison. Anopheline vaccination rate of Anopheles mosquitoes was 0.0038, and Anopheles sinensis was 0.000031. The malaria cases of local residents were estimated by proportion, accounting for 99.1% of Anopheles mosquitoes and 0.9% of Anopheles sinensis. The results show that: Anopheles Kunming is an efficient local media, its transmission of malaria is equivalent to 110 times the Anopheles sinensis.
