Seasonal weather, nutrients, and conspecific presence impacts on the southern house mosquito oviposition dynamics in combined sewage overflows

Combined sewage overflows have created favorable conditions for the establishment of the southern house mosquito, Culex quinquefasciatus Say (Diptera: Culicidae), larvae in natural creeks that would otherwise be unsuitable for the development of this mosquito species. Here, we show the results fr...

Here, we show the results from a seminatural experiment carried over the three seasons of mosquito activity (spring, summer, and fall) in Tanyard Creek, Atlanta, GA. In this study we manipulated the amount of nutrients by further enriching combined sewage overflow water, and tracked weather variables, organic nutrient concentration, exposure time to conspeciÞcs, and the number of egg rafts collected in experimental containers. We found season and nutrient enrichment to be the most important variables explaining the differences in egg rafts counts. Further analyses suggest that temperature may also play a role in seasonal oviposition patterns. The results from this study suggest that nutrient enrichment and adequate temperatures are important factors shaping Cx. quinquefasciatus oviposition seasonality in combined sewage overflows. Los desbordamientos de aguas residuales combinadas han creado condiciones favorables para el establecimiento de las larvas del mosquito doméstico del sur, Culex quinquefasciatus Say (Diptera: Culicidae), en arroyos naturales que, de otro modo, serían inadecuados para el desarrollo de esta especie de mosquito. En este caso, mostramos los resultados de un experimento seminatural llevado a cabo en las tres estaciones de actividad del mosquito (primavera, verano y otoño) en Tanyard Creek, Atlanta, GA. En este estudio manipulamos la cantidad de nutrientes enriqueciendo aún más el agua de sobreflujo de las aguas residuales combinadas, y realizamos un seguimiento de las variables meteorológicas, la concentración de nutrientes orgánicos, el tiempo de exposición a las conspeciÞcas y el número de balsas de huevos recogidas en los contenedores experimentales. La estación del año y el enriquecimiento de nutrientes fueron las variables más importantes variables que explican las diferencias en los recuentos de las balsas de huevos. Otros análisis sugieren que la temperatura puede desempeñar un papel en los patrones de oviposición estacional. Los resultados de este estudio sugieren que el enriquecimiento nutrientes y las temperaturas adecuadas son factores importantes que determinan la oviposición de Cx. quinquefasciatus de Cx. quinquefasciatus en los cauces de aguas residuales combinadas.
