INTRODUCTION
This study examined the parity of Anopheles mosquitoes and the influence of abiotic factors on the distribution of these mosquitoes in the Manso dam, Mato Grosso, Brazil.
METHODS
The anophelines were captured using the Human Attraction Technique for 12 h, while recording the temperature and relative humidity. Parity was determined by examining the conditions of the fi laments.
RESULTS
Anopheles darlingi and Anopheles triannulatus accounted for 98.5% of the anophelines, with 88% of these being parous.
CONCLUSIONS
Sudden variations in weather could be the cause of shifts from the total absence of mosquitoes to the appearance of females in abundance over a three-day period.
简介
本研究旨在探讨巴西马托格罗索州曼索大坝中按蚊的蚊种比例及其受非生物因素的影响。
方法
采用人诱捕法（12 小时）采集按蚊，同时记录温度和相对湿度。通过检查灯丝状况来确定蚊种的产卵情况。
结果
致倦库蚊和三带喙库蚊占捕获按蚊的 98.5%，其中 88%为孕蚊。
结论
天气的突然变化可能是导致在三天内蚊种数量从完全没有到大量雌蚊出现的原因。
