The diverse and complex environmental conditions of the Amazon Basin favor the breeding and development of Anopheles species. This study aimed to describe the composition, abundance and temporal frequency of Anopheles species and to correlate these factors with precipitation, temperature and relative humidity.
The study was conducted in the District of Coração, State of Amapá, Brazil. Samples were collected monthly during three consecutive nights, from 6:00 PM to 10:00 PM, from December 2010 to November 2011. In addition, four 12-hour collections (i.e., 6:00 PM to 6:00 AM) were performed during this period.
A total of 1,230 Anopheles specimens were collected. In the monthly collections, Anopheles darlingi was the predominant species, followed by An. braziliensis and An. albitarsis s.l., whereas An. darlingi, An. peryassui and An. braziliensis were the most frequent species collected in the 12-hour collections. The greatest number of anophelines was collected in September (the dry season). The highest frequency of anophelines was observed for An. darlingi during September, when there were the least rainfalls of the year, along with lower relative humidity and higher temperatures. There was little variation in the abundance of this species in other months, with the exception of slight increases in February, July and August.
The major malaria vectors, An. darlingi and An. albitarsis s.l. (likely An. marajoara), were the most abundant species collected in the study area. Consequently, prevention and control measures should be taken to prevent malaria outbreaks in the District of Coração.
亚马逊流域多样且复杂的环境条件有利于疟蚊属物种的繁殖和发育。本研究旨在描述疟蚊属物种的组成、丰度和时间频率，并将这些因素与降水、温度和相对湿度相关联。
本研究在巴西阿马帕州科拉索区进行。2010 年 12 月至 2011 年 11 月期间，连续三个月每月采集样本三次，每晚 6 点至 10 点进行。此外，在此期间还进行了四次 12 小时采集（即晚上 6 点至早上 6 点）。
共采集到 1230 只疟蚊标本。在每月采集的标本中，主要的物种是致倦库蚊，其次是巴西按蚊和带银环的按蚊，而在 12 小时采集的标本中，最常见的物种是致倦库蚊、佩氏按蚊和巴西按蚊。在 9 月（旱季）采集到的按蚊数量最多。致倦库蚊的出现频率最高，发生在一年中降雨量最少、相对湿度最低、温度最高的 9 月。除了 2 月、7 月和 8 月略有增加外，该物种在其他月份的数量变化不大。
主要的疟疾媒介，致倦库蚊和带银环的按蚊（可能是安氏按蚊），是研究区域中采集到的最丰富的物种。因此，应采取预防和控制措施，防止科拉索区疟疾爆发。
