Abstract

Montes Claros in Minas Gerais State, Brazil, was considered an intense transmission area for visceral leishmaniasis. This study evaluated sand fly fauna after insecticide application. Captures were performed in 10 districts from September 2005 to August 2006 with CDC light traps inside and outside each residence. Cypermethrin was sprayed in two cycles during November/2005 and May/2006. The 636 specimens collected, belonging to 10 species, were predominantly Lutzomyia longipalpis (79%), and most frequently males (70%). The highest percentage of specimens were captured in areas surrounding domiciles (85.8%). The main species were observed to be sensitive to treatment with the insecticide. The results showed a reduction in the number of sand flies collected after use of cypermethrin in homes and annexes, and with residual effect lasting from two to four months.

摘要

巴西米纳斯吉拉斯州的蒙蒂斯克拉鲁斯被认为是内脏利什曼病的高强度传播区。本研究评估了在应用杀虫剂后沙蝇区系的变化。于 2005 年 9 月至 2006 年 8 月在 10 个区使用美国疾病预防控制中心的诱捕器，在每个住所内和周围进行捕获。在 2005 年 11 月和 2006 年 5 月进行了两次氯菊酯喷雾。共收集到 636 只标本，属于 10 个种，其中以长刺革喙蚤（79%）为主，且雄性居多（70%）。在家居周围地区捕获的标本比例最高（85.8%）。主要观察到的物种对杀虫剂处理敏感。结果表明，在家庭和附属建筑物中使用氯菊酯后，沙蝇数量减少，且残留效果可持续两到四个月。
