Influence of climatic variables on the Aedes aegypti and Culex quinquefasciatus populations in Mato Grosso, Brazil

Authorship SCIMAGO INSTITUTIONS RANKINGS

Abstract

INTRODUCTION:

Aedes aegypti and Culex quinquefasciatus are vector species responsible for the transmission of important arboviruses.

METHODS:

Adult mosquitoes were collected in the urban areas of four municipalities in Mato Grosso within 1 year.

RESULTS:

A total of 19,110 mosquitoes were collected. Among them, 16,578 (86,8%) were C. quinquefasciatus (44% female and 56% male); 2,483 (13%), A. (Stegomyia) aegypti (54% female and 46% male); and 49 (0,30%), from the genus Psorophora, Anopheles, Coquilettidia, and Sabethes. A significant correlation was observed between the number of mosquitoes from all species and dew point (female mosquitoes, p = 0.001; male mosquitoes, p = 0.001).

CONCLUSIONS:

The results of this study may be used as environmental indicators of mosquito populations.
