Biological and ecological relations among vectors and their pathogens are important to understand the epidemiology of vector-borne diseases. Camapuã is an endemic area for visceral and tegumentary leishmaniasis. The aim of this study was to characterize the sandfly fauna present in Camapuã , MS, Brazil. Sand flies were collected every fortnight from May 2014 to April 2015 using automatic light traps in the domicile and peridomicile of twelve neighborhoods and forest. The collected specimens were identified based on morphology according to the valid identification keys. In total, 2005 sandflies of five genera and nine species were collected. Nyssomyia whitmani and Lutzomyia cruzi were the most abundant species. Males were more abundant, with a male-to-female ratio of 2.14. The highest diversity was observed in peripheral neighborhood, with abundant plant cover. The peridomicile presented greater abundance of sandflies, with the predominance of Ny. whitmani . No significant correlation between the absolute frequencies of the most abundant species and the precipitation variable was observed; however, there was a predominance of Lu. cruzi in the rainy season. We observed a high frequency of sandflies in urban area, especially vector species. The presence of Nyssomyia whitmani and Lutzomyia cruzi indicate the necessity for health surveillance in the municipality. Additional method of collection such as sticky trap is also recommended for appropriate faunestic study.
病媒与其病原体之间的生物学和生态关系对于理解病媒传播疾病的流行病学至关重要。卡马普阿是内脏利什曼病和皮肤利什曼病的流行地区。本研究的目的是对巴西马托格罗索州卡马普阿存在的白蛉种类进行特征描述。2014年5月至2015年4月期间，每两周使用自动诱虫灯在12个社区的住所和住家周围以及森林中收集白蛉。根据有效的鉴定指南，依据形态学对收集到的标本进行鉴定。总共收集到了5属9种的2005只白蛉。惠特曼按蚊和克鲁兹罗蛉是数量最多的种类。雄性白蛉数量更多，雌雄比例为2.14。在外围社区观察到最高的多样性，那里有丰富的植被覆盖。住家周围白蛉数量更多，以惠特曼按蚊为主。未观察到数量最多的种类的绝对频率与降水变量之间存在显著相关性；然而，在雨季克鲁兹罗蛉占优势。我们在城市地区观察到白蛉的高频率出现，尤其是病媒种类。惠特曼按蚊和克鲁兹罗蛉的存在表明该市有必要进行健康监测。还建议采用其他收集方法，如粘性诱捕器，以进行适当的动物区系研究。
