BARRETO, Mauricio; BURBANO, María Elena  and  BARRETO, Pablo. Records of Lutzomyia (Diptera: Psychodidae) in new localities of Colombia. Colomb. Med. [online]. 2006, vol.37, n.1, pp.39-45. ISSN 1657-9534.

Introduction: Phlebotomine sand flies are biological vectors of bacteria, protozoa and viruses attacking both human beings and animals. Sand flies are important since females have haematophagous habits and transmit various types of leishmaniases. In Colombia different studies have given the geographic distribution of these insects. This paper reports the finding of species in several localities and includes some places with no previous records. Material and methods: Specimens were captured while attempting to bite on collectors and with traps (light bait and animal bait). Other specimens were trapped in resting places. Sand flies were processed with different techniques regularly used for dissecting and mounting them for species identification. Results: From the study of 716 specimens, 124 males and 592 females, of the genus Lutzomyia in 46 places from 29 municipalities, in 11 departments (= states, provinces) it was possible to identify 33 species. Discussion: The geographic distribution of the genus Lutzomyia is being greatly extended to new Colombian localities. The importance of some anthropophilic species as vectors of diseases, mainly leishmaniases is discussed. The necessity of systematic and taxonomic studies to know the role of these insects in the transmission of pathologies affecting humans is emphasized.
