Seasonality modulates the direct and indirect influences of forest cover on larval anopheline assemblages in western Amazônia

Abstract Serious concerns have arisen regarding urbanization processes in western Amazônia, which result in the creation of artificial habitats, promoting the colonization of malaria vectors. We used structural equation modelling to investigate direct and indirect effects of forest cover on larval h...

We used structural equation modelling to investigate direct and indirect effects of forest cover on larval habitats and anopheline assemblages in different seasons.

Forest cover had direct and indirect (through limnological variables) effects on the composition of larval anopheline assemblages in the rainy season.

Additionally, artificial larval habitats promote ideal conditions for malaria vectors in Amazonia, mainly during the rainy season, with positive consequences for anopheline assemblages.
