| Popis: | This study was funded by the University of Granada (Centro de Ini-ciativas de Cooperacion al Desarrollo, CICODE, 2013) . We thanks the Delegation du Ministe`re de la Sante, province de Settat, Morocco, and the colleagues from the El Borouj health center. Funding for open access charge: Universidad de Granada/CBVA. Cutaneous leishmaniasis due to Leishmania tropica represents a major public health problem due to its ability to spread into non-endemic areas by means of its vectors, and the associated dramatic psychosocial impact. The objective of this work was to compare the intra and extradomiciliary density, sex ratio and gonotrophic stage of sand flies from a recent active focus in Morocco. This field study is based on the need to optimize the effectiveness of control programs. Two different capture methods, CDC light traps and sticky traps, were used at two different times of the year, corresponding with the peaks of sand fly abundance. 7,815 sand flies were captured and classified into 13 species belonging to genera Sergentomyia (50.8%) and Phlebotomus (49.2%). Phlebotomus sergenti was the most abundant and frequent species of the genus Phlebotomus both inside (49.3%) and outside houses (52.1%) and it showed the highest density in extradomiciliary captures in June. The proportion of bloodfed females was similar indoors and outdoors (21.5% and 26.3%, respectively). Females in the three gonotrophic stages were found in 26% houses and this was significantly associated with some factors related to housing conditions. Therefore, P. sergenti seems well adapted to both indoors and outdoors biotopes where these females coexist with males. These findings suggest that the adoption of additional measures could benefit the strategy of the Moroccan health authorities, currently consisting of indoor insecticide spraying, given that transmission may also occur outdoors.
