“…The closeness between the houses and the domestic animal shelters may account for the presence of insects indoors together with their capacity of endophilia. The high frequency of male insects found in both intra-and peridomiciliary areas has corroborated data provided by Oliveira et al (2003Oliveira et al ( , 2006, Resende et al (2006), Barata et al (2004Barata et al ( , 2005, evidencing the high adaptation capacity of sand flies enabling the disease transmission. The process of urbanization of insects and, consequently, of the disease is correlated with disorganized urban growth, followed by human migration from rural to urban regions and the environmental destruction.…”

“…La mayoría de los factores ambientales que afectan la epidemiología de varias leishmaniasis son aún pobremente entendidos o no se conocen muy bien (3,4). El estudio del comportamiento, de los hábitos alimentarios de Lutzomyia y de los factores que influyen sobre ellos resultan de gran importancia y contribuyen a la comprensión de la epidemiología de las leishmaniasis (4,5).…”

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.

Introduction:The sandfl y fauna is well studied globally. In Brazil, sandfl y fauna is very diverse in the Northeast region, especially in states such as Maranhão, Ceará, and Bahia. However, in the State of Pernambuco, the distribution of these insects is still not well known. Therefore, the objective of this study was to identify the different species that constitute the sandfl y fauna in an urban area in the Northeast region of Brazil, where an outbreak of visceral leishmaniasis (VL) was recently reported. Methods: The sandfl ies were collected from an urban area endemic for VL, at fi ve collection points. The collection of samples was carried out from November 2014 to December 2015, using CDC light traps installed in intradomiciliary and peridomiciliary fashion. Results: The collected sandfl ies (n = 297) belonged to eight species: Lutzomyia lenti, Lutzomyia longipalpis, Lutzomyia sallesi, Lutzomyia migonei, Lutzomyia walkeri, Lutzomyia capixaba, Lutzomyia carmelinoi, and Lutzomyia whitmani. Most of the specimens collected were peridomiciliary (247/297, 83%). L. lenti (154/297, 52%) was the most frequently sampled species, followed by L. longipalpis (88/297, 29.6%), and L. sallesi (42/297, 14.1%), which together accounted for over 90% of the collected sandfl y specimens. Conclusions: The continued presence of L. longipalpis in urban areas, including that in intradomiciliary areas, with a predominance of females, is crucial because of the high possibility of them causing VL outbreaks, since this species is the main vector of Leishmania infantum in Brazil.
