The order Diptera (Nematocera) is of epidemiological importance worldwide because of the hematophagy of females of several families that act as pathogen vectors. In Argentina, Culicidae (seven genera), Psychodidae (four), Ceratopogonidae (four) are pathogen vectors. The main objective of this work was to conduct a survey of the families of medical and veterinary importance. The specific objective was to recognize the genera involved in the transmission of diseases present in the area. Ten houses were selected based on previous entomological studies. Catches were made for two consecutive days using CDC light minitraps. The most abundant family was Psychodidae (n=9840) [Migonemyia (48%), Nyssomyia (20%) and Evandromyia (2%)], followed by Ceratopogonidae (n=358) [Forcipomyia (27%) and Culicoides (11%)] and Culicidae (n=230) [Culex (71%), Anopheles (28%) and Aedes (1%)]. These are preliminary results; it is important in the future to determine whether there are differences between houses in terms of abundance and their relationship with weather variables. The spatio-temporal studies of these families are the basis to determine their dynamics and distribution throughout the year so as to propose valid tools for their control and prevention.
