导言：这项研究的目的是对南马托格罗索州蓬塔波拉市的城市血吸虫动物群进行分析，并对感染(居民区内和寄生虫区)进行调查。方法：2005年9月至2007年9月，用CDC全自动捕蝇器采集沙蝇，连续3晚按月安装，时间为18h~6h。结果：共捕获到3,946种血吸虫，分别代表8个种，其中以长柄褐藻为优势种，呈现出较高的频度、稳定性、丰度和优势度指数。其中男性占82.9%，女性占17.1%。月平均捕获雄性数量(136.29+/-152.01)，远远多于女性。尽管居所内的平均血液量明显高于居室外，但差异无统计学意义。静脉素的丰度与平均日最高温度、降雨量和大气相对湿度呈正相关。结论：在Ponta Pora市，Lutzomia long gipalpis的优势引起了人们对该地区可能爆发内脏利什曼病的担忧，因为该物种不仅是南马托格罗索州乃至全国范围内的主要利什曼查加西媒介。
Introduction: The aim of this study was to carry out an analysis of urban phlebotomine fauna and a survey of infestations (intradomiciliary and peridomiciliary) in Ponta Pora municipality State of Mato Grosso do Sul. Methods: Sand flies were collected with automatic CDC light traps, installed monthly on three consecutive nights, from 18h to 6h, from September 2005 to September 2007. Results: A total of 3,946 phlebotomines, representing eight species, were captured, among which was a large predominance of Lutzomyia longipalpis, presenting high indexes of frequency, constancy, abundance and dominance. Of the total, 82.9% were males and 17.1% females. The monthly average number (136.29 +/- 152.01) of males captured being, much larger than that of females. Although the average number of phlebotomines in the intradomicile was much larger than that in the peridomicile, there was no significant statistical difference. A positive correlation was found between the abundance of phlebotomines and the average daily maximum temperature, precipitation and relative atmospheric humidity. Conclusions: The predominance of Lutzomyia longipalpis in Ponta Pora municipality is a reason for concern as regards the possibility of outbreaks of visceral leishmaniasis in the area, because this species is the main Leishmania chagasi vector not only in Mato Grosso do Sul but also nationwide.
