Registros de lutzomyia (Diptera: Psychodidae) en nuevas localidades de Colombia / Records of lutzomyia (Diptera: Psychodidae) in new localities of Colombia

Introducción: Los insectos del género Lutzomyia son vectores biológicos de bacterias, protozoarios y virus que atacan tanto a los seres humanos como a los animales. Tienen importancia sobre todo por cuanto las hembras, que son hematófagas, transmiten las diversas formas de leishmaniasis. En Colombia diferentes estudios han comunicado la distribución geográfica de estos dípteros. Con el presente trabajo se informan las especies en distintas localidades y se incluyen varios lugares sin registros conocidos antes. Materiales y métodos: Los ejemplares de este estudio se capturaron cuando pretendían picar a los colectores y con trampas donde el cebo era la luz o un animal. Varios especimenes se atraparon en sitios de reposo. A los flebótomos así obtenidos se les trató con diversos sistemas para poder disecarlos y montarlos entre lámina y laminilla a fin de hacer las identificaciones hasta especie. Resultados: A partir del estudio de 716 representantes, 124 machos y 592 hembras del género Lutzomyia, en 46 sitios de 29 municipios, 11 departamentos, fue posible identificar 33 especies. Discusión: Se amplía en forma considerable la distribución geográfica de los miembros del género Lutzomyia en varios sitios de Colombia. Se menciona la importancia de algunas especies antropofílicas en su responsabilidad como transmisores de enfermedades, sobre todo de las distintas leishmaniasis y se destaca la necesidad de estudios sistemáticos y taxonómicos a fin de fijar sus papeles en la diseminación de agentes patógenos que afectan a los seres humanos.

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.

Flies (Calliphoridae, Muscidae) and Beetles (Silphidae) from human cadavers in Cali, Colombia

Adult specimens of Cochliomyia macellaria, Chrysomya megacephala, Ch. rufifacies, Lucilia sp. (Calliphoridae), Musca domestica (Muscidae), Oxelytrum discicolle (Silphidae) and Sarcophagidae were recovered from 12 human cadavers in Cali, Valle, Colombia. Information regarding these findings is presented

Lutzomyia sand flies (Diptera: Psychodidae) from middle and lower Putumayo Department, Colombia, with new records to the country

A total of 4,840 phlebotomine sand flies from 54 localities in Putumayo department (=state), in the Colombian Amazon region, were collected in Shannon traps, CDC light traps, resting places and from human baits. At least 42 Lutzomyia species were registered for the first time to the department. Psychodopygus and Nyssomyia were the subgenera with the greatest number of taxa, the most common species being L. (N.) yuilli and L. (N.) pajoti. They were sympatric in a wide zone of Putumayo, indicating that they should be treated as full species (new status). Among the anthropophilic sand flies, L. gomezi and L. yuilli were found in intradomiciliar, peridomestic, urban or forest habitats. L. richardwardi, L. claustrei, L. nocticola and L. micropyga are reported for the first time in the Colombian Amazon basin. L. pajoti, L. sipani and L. yucumensis are new records for Colombia.
