Abstract

INTRODUCTION

An entomological study was conducted as part of a vector-monitoring program in the area associated with the Santo Antônio hydroelectric system in State of Rondônia, Western Amazonian Brazil.

METHODS

Fourteen sampling sites were surveyed to obtain data on the potential vectors of Leishmania spp. in the area. Sand flies were collected from 2011 to 2014 during the months of January/February (rainy season), May/June (dry season), and September/October (intermediary season) using light traps arranged in three vertical strata (0.5, 1, and 20m).

RESULTS

A total of 7,575 individuals belonging to 62 species/subspecies were collected. The five most frequently collected sand flies were Psychodopygus davisi (Root) (36.67%), Trichophoromyia ubiquitalis (Mangabeira) (8.51%), Nyssomyia umbratilis (Ward & Fraiha) (6.14%), Bichromomyia flaviscutellata (Mangabeira) (5.74%), and Psychodopygus complexus (Mangabeira) (5.25%). These species have been implicated in the transmission of American cutaneous leishmaniasis agents in the Brazilian Amazon region and described as potential vectors of this disease in the study area.

CONCLUSIONS

Additional surveillance is needed, especially in areas where these five species of sand fly are found.

摘要

引言

作为巴西西部亚马逊朗多尼亚州圣安东尼奥水电系统相关地区病媒监测项目的一部分，开展了一项昆虫学研究。

方法

对14个采样点进行了调查，以获取该地区利什曼原虫潜在病媒的数据。2011年至2014年期间，于1月/2月（雨季）、5月/6月（旱季）和9月/10月（中间季），使用设置在三个垂直层次（0.5米、1米和20米）的诱虫灯收集白蛉。

结果

共收集到属于62个物种/亚种的7575只个体。收集频率最高的五种白蛉分别是达氏白蛉（Psychodopygus davisi）（Root）（36.67%）、泛栖毛蠓（Trichophoromyia ubiquitalis）（Mangabeira）（8.51%）、荫蔽柔蛉（Nyssomyia umbratilis）（Ward & Fraiha）（6.14%）、黄盾双色蛉（Bichromomyia flaviscutellata）（Mangabeira）（5.74%）和复杂白蛉（Psychodopygus complexus）（Mangabeira）（5.25%）。这些物种与巴西亚马逊地区美洲皮肤利什曼病病原体的传播有关，并在研究区域被描述为该疾病的潜在病媒。
