- Culicoides insignis Lutz and Culicoides paraensis Goeldi are known bluetongue virus and filariasis (caused by Mansonella ozzardi Manson) vectors, respectively. Bluetongue virus appears to be restricted to northeastern Argentina, while filariasis is endemic in the subtropical mountain forest of the Argentine northwest. With the objective of characterizing the abundance and seasonality of both Culicoides species, entomological sampling was carried out from Dec 2004 to Nov 2005 in the southern area of the forest of Tucumn province. The specimens were captured using CO2-baited CDC light traps placed in 2 types of environments, wild and anthropized. The abundance of the specimens in relation to environmental variables was analyzed using multiple linear regression. Out of the 2,497 adult specimens collected, 76.9% belonged to C. paraensis, 20.4% to C. insignis and the 2.5% belonged jointly to Culicoides debilipalpis Lutz, Culicoides lahillei Lutz and Culicoides venezuelensis Mirsa & Ortiz (2.5%), and 0.2% could not be identified. Peaks of abundance of C. insignis and C. paraensis in decreasing magnitude were observed in the fall, summer and spring, respectively; and the largest number of specimens was found in the anthropized environment. Mean minimum and maximum temperatures and levels of accumulated rainfall were the variables that best explained the abundance of these 2 species. The present work is an important contribution not only to the knowledge of the spatial and temporal distribution and dynamics of these vectors in nature, but also to the elucidation of the implications of anthropization of the forest environment, and the effect of these climatic variables as determinants of the abundance of the species and, hence, as determinants of the possible transmission of filariasis in the subtropical mountain forest of the Argentine northwest.
Culicoides insignis Lutz y Culicoides paraensis Goeldi son conocidos vectores del virus de la lengua azul (BTV) y de la filariasis (causada por Mansonella ozzardi Manson), respectivamente. El virus de la lengua azul aparece reportado para la región del noreste, mientras que la filariasis resulta endémica de la selva subtropical de montaña del noroeste de Argentina. Con el objetivo de caracterizar la abundancia y estacionalidad de ambas especies en el noroeste de la Argentina, se realizó un muestreo entomológico desde diciembre de 2004 a noviembre de 2005 en el área sur de la selva, en la provincia de Tucumán. Los ejemplares fueron capturados mediante trampas de luz CDC cebadas con CO2 y colocadas en dos tipos de ambientes, silvestre y antropizado. La abundancia de los ejemplares en relación a las variables ambientales fue analizada mediante regresiones lineales múltiples. Se recolectaron 2,497 especimenes adultos, de los cuales el 76.9% pertenecen a C. paraensis, el 20.4% a C. insignis y el resto a Culicoides debilipalpis Lutz, Culicoides lahillei Lutz y Culicoides venezuelensis Mirsa & Ortiz (2.5%). Se observaron picos de abundancia decrecientes para C. insignis y C. paraensis en otoño, verano y primavera; resultando el mayor número de ejemplares recolectados para el ambiente antropizado. La temperatura mínima y máxima media y los niveles de precipitación acumulada, fueron las variables que mejor explicaron la abundancia de ambas especies. El presente trabajo resulta una importante contribución no sólo por ampliar el conocimiento de la distribución temporo-espacial y de la dinámica de estos vectores en la naturaleza, sino también por tratar de dilucidar la implicancia de la antropización de los ambientes selváticos y del efecto de las variables climáticas sobre la abundancia de las especies y por lo tanto, de la posible transmisión de la filariasis en la selva subtropical de montaña del noroeste de Argentina.
