Culicidae Fauna (Diptera: Culicomorpha) of the Quilombola Community of Abacatal, Ananindeua, Pará, in the Brazilian Amazon

Abstract

The Quilombola community of Abacatal, located in Ananindeua, in the state of Pará, has characteristics that favor the proliferation of mosquitoes. Faunal surveys in environmental preservation areas are essential for understanding the dynamics of these vectors, whose epidemiological implications are significant. Uncontrolled human activities have an impact on temperature, humidity, and rainfall. The aim of this study was to survey the diversity of mosquito species in the Quilombola community of Abacatal. Field collections were carried out over 10 days, during the rainy and dry seasons, using the following methods: protected human attraction (PHA) and CDC traps. The results of the taxonomic identification of the samples collected revealed that the species Coquillettidia (Rhynchotaenia) venezuelensis and Culex (Melanoconion) portesi were eudominant in the area studied. The identification of species of epidemiological importance, which act as vectors for various arboviruses, highlights the relevance of monitoring in the area, especially considering that it will undergo a process of anthropization.
