- Due to several epizootic events between 2020 and 2021 in the south of Brazil near the border with Argentina, we performed mosquito surveys in areas of epidemiological risk in northeast Argentina to evaluate abundance and distributions of mosquito vectors from the yellow fever virus (YFV) (Diptera: Culicidae). For the most abundant species, the number of individuals captured per collector was evaluated based on the capturing time range. With a total sampling effort of 191 collector-hours, we captured 676 mosquitoes belonging to 6 genera and 16 species. The most abundant species were Aedes (Ochlerotatus) scapularis (Rondani) (33.58%), Sabethes (Sabethes) albiprivus Theobald (20.27%), Aedes (Stegomyia) albopictus (Skuse) (17.75%) and Haemagogus (Conopostegus) leucocelaenus (Dyar and Shannon) (15.86%). Sabethes albiprivus and Ae. albopictus showed activity peaks at noon and morning, respectively, while other species showed no important time differences between 10:00AM and 15:00PM. Our results show that the most abundant mosquito species in those environments with epidemiological risk in northern Corrientes and southern Misiones are categorized as important in the transmission of the YFV. Moreover, we report an expansion of Ae. albopictus distribution and the first record of Aedes (Ochlerotatus) patersoni Shannon and Del Ponte in Corrientes and Misiones provinces.
Debido a varios eventos epizoóticos entre 2020 y 2021 en el sur de Brasil, cerca de la frontera argentina, realizamos muestreos con el fin de evaluar la abundancia y distribución de los mosquitos (Diptera: Culicidae) vectores del virus de la fiebre amarilla en áreas de riesgo epidemiológico del noreste de Argentina. Además, para las especies más abundantes, se evaluó el número de individuos capturados por colector en función del tiempo. Con un esfuerzo de muestreo total de 191 horas-colector se capturaron 676 mosquitos pertenecientes a 6 géneros y 16 especies. Las especies más abundantes fueron Aedes (Ochlerotatus) scapularis (Rondani) (33.58%), Sabethes (Sabethes) albiprivus Theobald (20.27%), Aedes (Stegomyia) albopictus (Skuse) (17.75%) y Haemagogus (Conopostegus) leucocelaenus (Dyar y Shannon) (15.86%). Sabethes albiprivus y Ae. albopictus mostraron picos de actividad, mientras que el resto de las especies presentaron actividad sin diferencias entre las 10:00AM y las 15:00PM. Nuestros resultados evidencian que las especies de mosquitos más abundantes en ambientes con riesgo epidemiológico se encuentran incriminadas en la transmisión del virus de la fiebre amarilla. Por otro lado, informamos sobre una expansión de la distribución de Ae. albopictus en el país y el primer registro de Aedes (Ochlerotatus) patersoni Shannon y Del Ponte en las provincias de Corrientes y Misiones.
