Abstract: El primer caso autóctono de leishmaniasis visceral (LV) en la Argentina se notificó en el a o 2006 en Posadas, Misiones, y en el verano 2008-2009 se comprobó la dispersión del vector de LV, Lutzomyia longipalpis y casos de LV canina en la provincia de Corrientes. Para conocer la distribución del riesgo, entre febrero y marzo del 2010 se realizó la búsqueda sistemática del vector de LV en 18 localidades de las provincias de Entre Ríos, Corrientes y en la ciudad de Puerto Iguazú, Misiones, totalizando 313 trampas/noche. Se comprobó la presencia de Lu. longipalpis, por primera vez, en las localidades de Chajarí (Entre Ríos), Alvear, La Cruz, Curuzú Cuatiá y Bella Vista (Corrientes), y en Puerto Iguazú (Misiones). En Santo Tomé y Monte Caseros (Corrientes) se volvió a registrar la presencia del vector, y se obtuvieron las trampas con más ejemplares, 830 y 126 Lu. longipalpis trampa/sitio/noche respectivamente. Los resultados muestran que el vector de la LV urbana, continúa dispersándose en el territorio argentino. Simultáneamente, la propagación del parásito, y los consecuentes casos de LV humana se asocian al aumento de reservorios, perros infectados con o sin clínica, debidos al tránsito humano. The first case of visceral leishmaniasis (VL) in Argentina was reported in 2006 in Posadas, Misiones. During the summer 2008-2009 Lutzomyia longipalpis, the VL vector, and canine VL cases were already spread along the province of Corrientes. In order to know the distribution of VL risk, systematic captures of the vector were performed between February and March 2010, in 18 areas of the provinces of Entre Ríos and Corrientes, and the city of Puerto Iguazú, Misiones, with a total of 313 traps/night. We confirmed the presence of Lu. longipalpis, for the first time in Chajarí (Entre Ríos), Alvear, La Cruz, Curuzú Cuatiá and Bella Vista (Corrientes), and Puerto Iguazú (Misiones). In Santo Tome and Monte Caseros (Corrientes), where the vector had been previously reported, traps with more samples were obtained with 830 and 126 Lu. Longipalpis trap/site/night respectively. These results show that the vector of urban VL continues spreading in the Argentine territory. Simultaneously, the spread of the parasite and the resulting human VL cases are associated with the dispersion of reservoirs, infected dogs, with or without clinical symptoms or signs, due to human transit.

Abstract: phlebotomine captures were performed in february 2010 in salto (salto department) and bella unión-cuarein (artigas department), uruguay. bella unión is located across the paraná river from monte caseros, argentina, where a focus of canine visceral leishmaniasis (vl) was reported in 2009. no vl cases have ever been recorded in uruguay and the last reported capture of phlebotominae was in 1932 (lutzomyia cortelezzii and lutzomyia gaminarai). light traps were placed in peridomestic environments, and lutzomyia longipalpis, the main vector of visceral leishmaniasis, was found in salto and bella unión. this is a first report of an area of potential vl transmission in uruguay. active and coordinated surveillance is required immediately the uruguay-argentina-brazil border area.

Description of the fourth instar larva of Lutzomyia longipalpis, under scanning electron microscopy

Memórias do Instituto Oswaldo Cruz , 1996, DOI: 10.1590/S0074-02761996000500007
Abstract: the fourth instar larva of lutzomyia (lutzomyia) longipalpis (phlebotomidae: phlebotominae) was studied by scanning electron microscope. based on three-dimensional observations, the fine structure and setal position (using of setal numeration) of the larva are presented.
The First Instar Larva of Lutzomyia longipalpis (Diptera: Phlebotomidae)
Memórias do Instituto Oswaldo Cruz , 1997, DOI: 10.1590/S0074-02761997000200011
Abstract: the morphology and chaetotaxy of the first instar larva of lutzomyia (lutzomyia) longipalpis are described based on observations made under scanning electron microscope. because three-dimensional images were studied, some terminological changes are proposed to give a more realistic description of the positions of the setae. on the larval body, the pairs of setae have the following number: 9 on the head, 12 on the prothorax, 8 on the meso- and metathorax, 6 on the first to eighth abdominal segments, and 8 on the ninth abdominal segment

Abstract: lutzomyia longipalpis, 15 other species of the genus lutzomyia, and one species of brumptomyia were collected in an endemic focus of cutaneous leishmaniasis in a river canyon 450 m above sea-level, in rio claro, antioquia, colombia. the presence of lu. longipalpis is associated with the destruction of the primary forest and the development of new farmland and rural settlement in this region. the composition of species identified a different habitat for lu. longipalpis in colombia. lu. yuilli and lu. longipalpis were predominant (68.26%) followed by lu. trapidoi, lu. hartmani, lu. triramula, lu. panamensis, lu. gomezi.
Lutzomyia longipalpis (Diptera: Psychodidae: Phlebotominae): a review
Soares, Rodrigo P. P.;Turco, Salvatore J.;

Abstract: lutzomyia longipalpis is the most important vector of americanvisceral leishmaniasis (avl) due to leishmania chagasi in the new world. despite its importance, avl, a disease primarily of rural areas, has increased its prevalence and became urbanized in some large cities in brazil and other countries in latin america. although the disease is treatable, other control measures include elimination of infected dogs and the use of insecticides to kill the sand flies. a better understanding of vector biology could also account as one more tool for avl control. a wide variety of papers about l. longipalpis have been published in the recent past years. this review summarizes our current information of this particular sand fly regarding its importance, biology, morphology, pheromones genetics, saliva, gut physiology and parasite interactions.
