Distribuição espacial e sazonalidade de mosquitos (Diptera: Culicidae) em área verde urbana

Abstract

The mosquitoes (Diptera: Culicidae) are widely known to transmit a variety of pathogens, with Aedes aegypti and Aedes albopictus considered the main vectors of arboviruses worldwide. Its development can be affected by seasonality, factors biotic and abiotic. In this study, we describe the spatial distribution pattern and the effect of seasonality on the mosquito community that colonize artificial containers in three environments of ecotone in the city of Montes Claros, focusing on the invasive species Aedes aegypti and Aedes albopictus. The collect of Immature was carried out through ovitraps, and adults were collected using Shannon's traps and colkect protected and enlightened. The abundance of Aedes aegypti and Aedes albopictus was correlated with the percentage of shading, environment, amount of organic matter and station. A total of 539 immature mosquitoes and 957 adult individuals were collected, with Aedes albopictus being the most abundant species in the immature collect and Aedes scapularis predominating in the adult sampling. Regarding the analyzed variables, it was observed that the organic matter did not influence the abundance of Aedes, while the percentage of shading, station and environment was significant for both. In the pasture area, a greater number of culicids was obtained, in addition, it was observed that seasonality proved to be a determining factor in the abundance of species, since there was greater abundance in the rainy station. The wealth of adult mosquitoes collected was reasonably high for a green peri-urban area in a medium-sized city like Montes Claros.
