Forty five percent of malaria cases in the department of Santander, Colombia originate in the municipality of Cimitarra. This locality has reported cases from the rural and urban areas. The population between 15 and 45 years of age is the most affected. Additionally, Cimitarra has registered malaria cases in children under 1 year of age.
To determine the biology and behavioral aspects of Anopheles mosquitoes from Cimitarra to more effectively orient control strategies.
During October to December/2002 and March/2003, anopheline collections were undertaken. Isofamilies were obtained from 620 wild females.
The following species were found in order of abundance: Anopheles (Nyssorhynchus) triannulatus (Neiva y Pinto 1922), Anopheles (Nyssorhynchus) nuneztovari Gabaldón 1940, Anopheles (Nyssorhynchus) rangeli Gabaldón, Cova-García y López 1940, Anopheles (Anopheles) pseudopunctipennis Theobald 1901, Anopheles (Anopheles) mattogrosensis Lutz y Neiva 1911 and Anopheles (Anopheles) neomaculipalpus Curry 1933. The highest biting rate (0.5) was recorded for An. nuneztovari and An. triannulatus indoors between 20-21 hours. Forty two breeding places were sampled, 81% were fish ponds, 9.5% puddles and 2.3% cement tanks. Eighty seven percent of fish ponds were located near dwellings, being positive for anopheline larvae.
This study has shown that in Cimitarra cryptic and sister species of Anopheles genus occur in sympatry, Nyssorhynchus subgenera.
哥伦比亚桑坦德省45%的疟疾病例源自西米塔拉市。该地区报告了农村和城市地区的病例。15至45岁的人群受影响最大。此外，西米塔拉还记录到1岁以下儿童的疟疾病例。
确定西米塔拉按蚊的生物学和行为特征，以便更有效地指导控制策略。
在2002年10月至12月以及2003年3月期间，进行了按蚊采集。从620只野生雌蚊中获得了同家族群。
按丰度顺序发现了以下物种：三带按蚊（尼氏按蚊）（Neiva y Pinto，1922年）、努内斯按蚊（尼氏按蚊）（Gabaldón，1940年）、兰热利按蚊（尼氏按蚊）（Gabaldón、科瓦 - 加西亚和洛佩斯，1940年）、伪点按蚊（按蚊）（Theobald，1901年）、马托格罗索按蚊（按蚊）（Lutz y Neiva，1911年）和新黄斑按蚊（按蚊）（Curry，1933年）。努内斯按蚊和三带按蚊在室内20 - 21时的叮咬率最高（0.5）。对42个繁殖地进行了采样，81%是鱼塘，9.5%是水坑，2.3%是水泥池。87%的鱼塘位于住宅附近，按蚊幼虫呈阳性。
本研究表明，在西米塔拉，按蚊属的隐种和姐妹种在尼氏按蚊亚属中共存。
