          Abstract

          La región geográfica denominada Chocó-Darién-Caribe es uno de los ecosistemas de bosque húmedo tropical de gran diversidad, pero aún poco explorado. El presente estudio documenta algunas especies de flebotomíneos colectados en un área de transmisión de leishmaniasis cutánea. Se realizó un estudio entomológico en la reserva natural el Aguacate, municipio de Acandí, Chocó. La metodología incluyó el uso de trampas de luz CDC y búsqueda activa en raíces tabulares, colectando con aspiradores bucales. Se recolectaron 1.205 individuos, de los cuales sobresalen Lutzomyia panamensis, Lutzomyia trapidoi, Lutzomyia gomezi, Lutzomyia sanguinaria, Lutzomyia olmeca bicolor y Lutzomyia hartmanni reconocidos como vectores potenciales de leishmaniasis cutánea en el nuevo mundo. Se relata el hallazgo de 16 especies del género Lutzomyia França y dos especies del género Brumptomyia Sherlock para la costa del Darién-Caribe colombiano, destacando la presencia de las especies Lutzomyia atroclavata (Knab) y Brumptomyia mesai (Sherlock) como nuevos registros para el departamento del Chocó. Este estudio aporta al conocimiento de la fauna de flebotomíneos del municipio de Acandí, Chocó.

          The geographic region called Chocó-Darién-Caribe is a tropical forest ecosystem considered of great diversity but still a poorly known region. The current study focuses on some phlebotominae species collected in a geographic area where it has been documented cutaneous leishmaniasis transmission. An entomological study was conducted at the Natural Reserve El Aguacate, in Acandí municipality, Chocó. Sampling methods included light traps such as CDC and collections of adult sand flies in resting sites such as tree buttresses using mouth aspirators devices. The collection findings comprise a total of 1205 phlebotominae adults, with some species of note such as Lutzomyia panamensis, Lutzomyia trapidoi, Lutzomyia gomezi, Lutzomyia sanguinaria, Lutzomyia olmeca bicolor and Lutzomyia hartmanni which are recognized as potential vectors of cutaneous leishmaniasis in the new world. Sixteen species of the genus Lutzomyia França and two species of the genus Brumptomyia Sherlock are recorded for the colombian Darién-Caribe region. The species Lutzomyia atroclavata (Knab) and Brumptomyia mesai (Sherlock) are new findings in Chocó. This study is a contribution to the phlebotominae species of Acandí municipality in Chocó.

          Natural breeding places of phlebotomine sandflies.

          Methods of finding larvae and pupae of phlebotomine sandflies (Diptera: Psychodidae) are described and the known types of breeding sites used by sandflies are listed. Three ways of detecting sandfly breeding places are the use of emergence traps placed over potential sources to catch newly emerged adult sandflies; flotation of larvae and pupae from soil, etc., and desiccation of media to drive out the larvae. Even so, remarkably little information is available on the ecology of the developmental stages of sandflies, despite their importance as vectors of Leishmania, Bartonella and phleboviruses affecting humans and other vertebrates in warmers parts of the world. Regarding the proven or suspected vectors of leishmaniases, information on breeding sites is available for only 15 out of 29 species of sandflies involved in the Old World and 12 out of 44 species of sandflies involved in the Americas, representing approximately 3% of the known species of Phlebotominae. Ecotopes occupied by immature phlebotomines are usually organically rich moist soils, such as the rain forest floor (Lutzomyia intermedia, Lu. umbratilis, Lu. whitmani in the Amazon; Lu. gomezi, Lu. panamensis, Lu. trapidoi in Panama), or contaminated soil of animal shelters (Lu. longipalpis s.l. in South America, Phlebotomus argentipes in India; P. chinensis in China; P. ariasi, P. perfiliewi, P. perniciosus in Europe). Developmental stages of some species (P. langeroni and P. martini in Africa; P. papatasi in Eurasia; Lu. longipalpis s.l. in South America), have been found in a wide range of ecotopes, and many species of sandflies employ rodent burrows as breeding sites, although the importance of this niche is unclear. Larvae of some phlebotomines have been found in what appear to be specialized niches such as Lu. ovallesi on buttress roots of trees in Panama; P. celiae in termite hills in Kenya; P. longipes and P. pedifer in caves and among rocks in East Africa. Old World species found as immatures in the earthen floor of human habitations include P. argentipes, P. chinensis, P. martini and P. papatasi. Much more information on sandfly breeding sites is required to facilitate their control by source reduction.

            A review of the geographic distribution and epidemiology of leishmaniasis in the New World.

            A review of the epidemiologic aspects of the New World leishmaniases, including their known geographic distribution, etiologic agents, zoonotic reservoirs, and insect vectors, based on biological and molecular characterization of Leishmania isolates is presented. Data summarized in this paper on parasite taxonomy and geographic distribution come from our studies of greater than 1,000 New World Leishmania isolates identified by species-specific monoclonal antibodies using an indirect radioimmune binding assay and from scientific literature.
