The study had the aim of characterizing the geographical distribution of Lutzomyia whitmani s.l. in the state of Maranhão, Northeastern Brazil. Between 1992 and 2005, 9,600 specimens (65.1% males and 34.9% females) were caught in the rural and urban zones of 35 municipalities in regions consisting of forests, savanna and mixed vegetation with coconut plantations, sandbanks and heath. Greater abundance was observed in areas surrounding dwellings (91.6%) than inside the dwellings (8.4%). The presence of the vector in different phytoregions and in rural and urban areas favors the transmission of tegumentary leishmaniasis in these environments. This taxon may constitute a complex of species in Maranhão, which can be confirmed by molecular biology studies.
El estudio tuvo por objetivo caracterizar la distribución geográfica de Lutzomyia whitmani s.l. en el estado de Maranhão, en Norte de Brasil. De 1992 a 2005, fueron capturados 9.600 especimenes (machos: 65,1% y hembras: 34,9%) en las zonas rurales y urbanas de 35 municipios situados en áreas de bosque, sabana y vegetación mixta con cocal, restinga y caatinga. La abundancia fue mayor en el peri domicilio (91,6%) con respecto al intra domicilio (8,4%). La presencia del vector en diferentes fitoregiones y en las áreas rurales y urbanas favorece la transmisión de la leishmaniasis tegumentar en esos ambientes. Es posible que ese taxón constituya un complejo de especies en el Maranhão, lo que podrá ser confirmado mediante estudios de biología molecular.
O estudo teve por objetivo caracterizar a distribuição geográfica de Lutzomyia whitmani s.l. no estado do Maranhão. De 1992 a 2005, foram capturados 9.600 espécimes (machos: 65,1% e fêmeas: 34,9%) nas zonas rurais e urbanas de 35 municípios situados em áreas de floresta, cerrado e vegetação mista com cocal, restinga e caatinga. A abundância foi maior no peridomicílio (91,6%) do que no intradomicílio (8,4%). A ocorrência do vetor em diferentes fitorregiões e nas áreas rurais e urbanas favorece a transmissão da leishmaniose tegumentar nesses ambientes. É possível que esse táxon constitua um complexo de espécies no Maranhão, o que poderá ser confirmado mediante estudos de biologia molecular.
