Abstract

INTRODUCTION

In the last decades, a considerable geographic expansion of the leishmaniases in all regions of Brazil has been observed. The present study was carried out to identify the composition of the phlebotomine sandfly fauna and verify the seasonal variation of the main species after environmental changes occurred in São Vicente Férrer Municipality, State of Pernambuco, Brazil.

METHODS

Captures were carried out during four consecutive nights of each month using Centers for Disease Control and Prevention light traps from September 2009 to September 2010. The correlation between the number of phlebotomine sandflies captured and climatic factors (temperature and rainfall) was evaluated.

RESULTS

A total of 13,872 specimens belonging to 20 species were captured, of which, 6,247 (45%) were females, and 7,625 (55%) were males. Lutzomyia migonei was the most abundant species with 9,964 (71.8%) specimens, being predominant in the intradomicile and peridomicile areas with 108 (86.4%) and 9,746 (97%), respectively. In the forest remnants, Lutzomyia complexa 2,395 (65%) and Lutzomyia sordellii 770 (20.8%) predominated. The correlation analysis between the total number of sandflies captured and climatic factors did not show a significant influence on population density.

CONCLUSIONS

The high abundance of Lutzomyia migonei and Lutzomyia complexa indicates the possibility of new cases of cutaneous leishmaniasis (CL).

摘要

简介

在过去的几十年中，观察到巴西所有地区的利什曼病都有相当大的地理扩张。本研究旨在确定塞阿拉州圣文森特费雷尔市环境变化后，按蚊的区系组成，并验证主要物种的季节性变化。

方法

使用疾病控制和预防中心的诱蚊灯，于 2009 年 9 月至 2010 年 9 月，连续四个月的每个月进行四次夜间捕获。评估捕获的按蚊数量与气候因素（温度和降雨量）之间的相关性。

结果

共捕获 13872 只标本，属于 20 个种，其中 6247 只（45%）为雌性，7625 只（55%）为雄性。卢茨蝇属米戈尼是最丰富的物种，有 9964 只（71.8%）标本，在家庭和周边地区分别占主导地位，分别有 108 只（86.4%）和 9746 只（97%）。在森林残余物中，卢茨蝇属复杂种 2395 只（65%）和卢茨蝇属 sordellii 770 只（20.8%）占优势。捕获的总按蚊数量与气候因素之间的相关分析并未显示对种群密度有显著影响。
