Knowledge of biological and ecological aspects of Culicoides is important because they are known filariasis vectors. The aim of this work was to determine the diversity, abundance and ecological aspects of Culicoides in San Miguel de Tucumán. Samplings were conducted during 2005-2006 in two areas, Jardín Botánico of the Fundación Miguel Lillo and Parque Guillermina, using CDC traps. 815 specimenes were collected and five species were identified: C. debilipalpis, C. insignis, C. lahillei, C. paraensis and C. venezuelensis. C. paraensis (50.3%) and C. debilipalpis (9.2%) were the most abundant species in the Jardín Botánico, and C. paraensis (47.8%) and C. venezuelensis (26.4%) in the Parque Guillermina. Multiple regression analysis determined that in the Jardín Botánico wind speed was the climatic variable most closely related to C. paraensis and C. debilipalpis (r2=0.48 p
