“…(24,26,27). Asimismo, las variaciones en el número de flebótomos activos se ven afectadas directamente por las condiciones ambientales, lo que explica que en las áreas geográficas diferentes los flebótomos muestren pautas de actividad diferentes (24,28,29).…”

Introducción. Se describen algunos aspectos de la ecología y de la importancia de las especies de Lutzomyia presentes en un foco de leishmaniasis en El Carmen de Bolívar, departamento de Bolívar. Objetivos. Establecer algunos de los patrones del comportamiento de las especies de Lutzomyia y asociar su posible papel en la transmisión de leishmaniasis en un foco de leishmaniasis visceral y cutánea. Materiales y métodos. Se utilizaron trampas CDC en diferentes hábitat, se hicieron capturas mensuales en cebo humano protegido en el intradomicilio y capturas en trampas Shannon en el extradomiclio. Estos datos se compararon con variables independientes, como precipitación, temperatura, humedad relativa y velocidad del viento mediante una correlación de Pearson para estimar el grado de asociación y determinar la influencia de las condiciones climáticas sobre la densidad de adultos de L. evansi y L. gomezi en diferentes hábitat.gomezi presentaron una relación significativa en la abundancia de adultos contra la velocidad del viento en el intradomicilio, las especies de Lutzomyia capturadas mostraron un comportamiento antropofílico con una actividad constante entre las 18:00 y las 20:00 horas. Conclusión. L. evansi y L. gomezi están en relación inversamente proporcional a la velocidad del viento, al disminuir, aumentan la actividad de las poblaciones de estas especies.Palabras clave: Leishmania, leishmaniasis/epidemiología, leishmaniasis visceral, leishmaniasis cutánea, Psychodidae, hábitat. Species of Lutzomyia involved in an urban focus of visceral and cutaneous leishmaniasisIntroduction. A focus of leishmanias transmission was reported in the municipality of El Carmen de Bolívar in the province of Bolívar, Colombia, where both cutaneous and visceral leishmaniasis cases have occured. Vector identification, ecology and behavior of potential vector species have not been characterized in this region, however. Objectives. Sand fly species of the genus Lutzomyia were identified, patterns of behavior were established, and their possible roles in leishmaniasis transmission were evaluated. Materials and methods. CDC light traps were used in several different habitats; in addition, monthly collections were made with human bait as attraction inside houses as well as outdoor Shannon trap collections. The collection data were compared with independent variables including precipitation, temperature, relative humidity and wind velocity by means of a Pearson correlation matrix to estimate levels of association and to determine the influence of the climatic conditions on the density of adults of Lutzomyia evansi and L. gomezi in each of the habitats. Results. Five species of Lutzomyia were captured: L. evansi, L. cayennensis cayennensis, L. gomezi, L. dubitans, and L. walkeri. Lutzomyia evansi and L. gomezi presented a significant relationship in the abundance of adults indoors with respect to outdoor wind velocity. The Lutzomyia species captured showed an anthropophagic behavior with a constant activity between the 18:00 and 20:00 hrs.

“…whitmani, however, has been regarded to be a species "under adaptation" to the urban environment by several investigators due to the fact that it is collected in high concentrations in thickly forested areas and in peridomiciliary areas of large centers (Camargo-Neves et al 2002, Dos Santos et al 2003, Salomón et al 2003, Oliveira et al 2003 and it has been associated with peridomiciliary transmissions in Brazilian Northeastern and Southeastern areas (Cuba-Cuba et al 1985, Azevedo & Rangel 1991, Rangel et al 1996. Due to this fact, several studies have been undertaken in order to better understand the biology of L. whitmani.…”

“…Usually, phlebotomines are found in high densities during rainy summer months (Gomes & Galati 1987, Salomón et al 2003. On the other hand, Condino et al (1998) have reported no relationship between such factors and the phlebotomine sand fly density.…”

“…The geographical distribution presented for Mg. migonei was based on the data base of the Cipa Group (1997) and complemented for some areas: Brazil: Rondônia (Gil et al 2003), Mato Grosso do Sul (Martins et al 1978), Rio Grande do Norte (Ximenes et al 2000), Alagoas (Saraiva et al 2006); Colombia: La Guajira (Barreto et al 2006); Peru: Pasco (Cáceres et al 2000); Paraguay: Amambay Guaira, Itapuá, Misiones (Salomón et al 2003).…”
