Synanthropic Culicidae (Diptera) in three fragments of Atlantic Forest in northern Parana, Brazil.

Synanthropic Culicidae were sampled using natural and artificial traps in three forest fragments (Daher Wood, Botanical Garden, and Mata dos Godoy State Park) in Londrina, Parana, Brazil. To collect Culicidae, six traps were distributed in two separate transects of 70 m each, parallel, with a distance between them of 30 m. Three traps were natural (bamboo) and the other three were artificial (tires). In total, we collected 15,048 specimens distributed in eight species. The peri-urban fragments showed the highest richness. Tires were preferred as breeding sites. The seasons of highest and lowest sampling were summer and winter. The Daher Wood and Botanical Garden showed high similarity, and the Godoy Wood, an intact environment, showed the greatest dominance. The mosquitoes demonstrated varying degrees of synanthropy. Correlations were positive between temperature (0.53) and precipitation (0.40) with Culicid abundance. The Principal Component Analysis indicated that tires were most influenced by temperature, relative humidity, and bamboos by Total Dissolved Solids. Four of the collected species showed potential to be vectors of etiological agents. Abiotic factors directly influence the biology of mosquitoes, which is reflected in higher diversity in warmer and rainy periods. Urban and peri-urban areas showed more synanthropic mosquitoes due to their preference for modified sites. Vector species in these areas are of concern because they can modify disease cycles, and for this reason, it is essential to monitor these areas.
