疟疾卷土重来已成为国内外的一个重要公共卫生问题，而对这种疾病的接受程度是其卷土重来的关键。盈江是中国中缅边境少数出现本地疟疾病例的县之一。本研究旨在了解 2016 年 6 月至 10 月中国盈江县对疟疾的感受性。采用光诱捕器捕获 8 个镇 17 个村庄的蚊子，这些村庄分为四个海拔级别：1 级，0-599 米；1 级，0-599 米； 2 级，600–1199 米； 3 级，1200–1799 米； 4 层，> 1800 米。物种丰富度、多样性、优势度和均匀度被用来描绘群落结构。比较不同海拔水平之间物种组成的相似性。 2016 年 6 月至 10 月，每月收集那邦镇和平原镇两镇的蚊子季节丰度、人类叮咬率、光诱成蚊和幼虫密度、经产率以及小按蚊和中华按蚊的高度分布（密度）数据。研究期间，共采集按蚊 10,053 只。 已鉴定出 8 个城镇和 15 种按蚊，其中最常见的是按蚊。中华按蚊（75.4%）、昆明按蚊（15.6%）和按蚊。最小值（3.5%）。微小按蚊是低海拔地区（< 600 米，即纳邦镇）的主要疟疾媒介。中海拔地区（600-1200米，即平原镇）。在那邦，安人咬人率最高。村内和村外的极小发生时间为2016年6月和8月，分别为5个/饵/晚和15个/饵/晚。平原地区，安族咬人率最高。八月份，内场9/饵/晚，外场21/饵/晚。这两个城镇表现出季节性丰度，两种成虫媒介密度很高：An 的峰值密度。最小值是六月，安是六月。中华是在八月。与此同时，An 幼虫密度达到峰值。极小值是七月，而安是七月。调查季节，中华冬虫夏草数量有所减少；微酸性水适合这些载体的生长。 An 的生育率。中华和安。最小值分别为 90.46 和 93.33%。按蚊群落分布在不同海拔高度。边境低海拔地区整个疫情季节结构复杂且稳定。两种按蚊媒介的高叮咬率、成虫和幼虫密度以及经产率表明中缅边境盈江县对疟疾的易感性极高。
The re-establishment of malaria has become an important public health issue in and out of China, and receptivity to this disease is key to its re-emergence. Yingjiang is one of the few counties with locally acquired malaria cases in the China–Myanmar border in China. This study aimed to understand receptivity to malaria in Yingjiang County, China, from June to October 2016. Light-traps were employed to capture the mosquitoes in 17 villages in eight towns which were categorized into four elevation levels: level 1, 0–599 m; level 2, 600–1199 m; level 3, 1200–1799 m; and level 4, > 1800 m. Species richness, diversity, dominance and evenness were used to picture the community structure. Similarity in species composition was compared between different elevation levels. Data of seasonal abundance of mosquitoes, human biting rate, density of light-trap-captured adult mosquitoes and larvae, parous rate, and height distribution (density) of Anopheles minimus and Anopheles sinensis were collected in two towns (Na Bang and Ping Yuan) each month from June to October, 2016. Over the study period, 10,053 Anopheles mosquitoes were collected from the eight towns, and 15 Anopheles species were identified, the most-common of which were An. sinensis (75.4%), Anopheles kunmingensis (15.6%), and An. minimus (3.5%). Anopheles minimus was the major malaria vector in low-elevation areas (< 600 m, i.e., Na Bang town), and An. sinensis in medium-elevation areas (600–1200 m, i.e., Ping Yuan town). In Na Bang, the peak human-biting rate of An. minimus at the inner and outer sites of the village occurred in June and August 2016, with 5/bait/night and 15/bait/night, respectively. In Ping Yuan, the peak human-biting rate of An. sinensis was in August, with 9/bait/night at the inner site and 21/bait/night at the outer site. The two towns exhibited seasonal abundance with high density of the two adult vectors: The peak density of An. minimus was in June and that of An. sinensis was in August. Meanwhile, the peak larval density of An. minimus was in July, but that of An. sinensis decreased during the investigation season; the slightly acidic water suited the growth of these vectors. The parous rates of An. sinensis and An. minimus were 90.46 and 93.33%, respectively. The Anopheles community was spread across different elevation levels. Its structure was complex and stable during the entire epidemic season in low-elevation areas at the border. The high human-biting rates, adult and larval densities, and parous rates of the two Anopheles vectors reveal an exceedingly high receptivity to malaria in the China–Myanmar border in Yingjiang County.
