[Spatial distribution of Lutzomyia longipalpis (Lutz & Neiva, 1912) and Lutzomyia cruzi (Mangabeira, 1938) in the State of Mato Grosso].
Visceral leishmaniasis is currently considered an emergent and reemergent disease, in agricultural and urban zones, both in domestic and peridomestic areas. The objective of this work was to verify the spatial distribution of Lutzomyia longipalpis and Lutzomyia cruzi in Mato Grosso State. Data from 1996 to 2004 was collected by the Entomology Laboratory, whose captures were carried with a CDC light trap. Sixty-eight of the 139 cities in the state have been studied. Lutzomyia longipalpis and Lutzomyia cruzi occurred in 23 and 22 cities, respectively. The results demonstrate the extensive occurrence of Lutzomyia longipalpis in areas with different vegetation types: savanna, transition and Amazon forest. Lutzomyia cruzi occurred mainly in cities with areas of marshland and savanna. Verification of the distribution of the vector populations in the state and their preferential vegetation type, provides an indication of vulnerable and/or receptive areas for disease transmission.
