摘要：

Urban increase of visceral leishmaniasis (VL) in Brazil is associated with the adaptation of its vector, Lutzomyia longipalpis, to environments modified by humans The present study reports the results of an entomological monitoring of L longipalpis and the effect of environmental variables on its population density Sandflies were captured in the municipality of Mossoro, State of Rio Grande do Norte, Northeastern Brazil, from January 2005 to December 2006 Two CDC light traps were placed monthly for four consecutive nights in the peridomicile of selected households Data analysis was based on the chi-square test and linear regression A total of 2,087 sandflies were captured, 99 86% of which were L longipalpis A higher proportion of females were captured (p < 0 05) Monthly analysis of the variables temperature, relative humidity and rainfall did not show a significant influence on population density However, there we, e seasonal differences approximately 70% of sand flies were captured during the rainy season (p < 0 05) The predominant species, L longipalpis, is present in substantial number, representing a public health risk Therefore, because of higher prevalence during the rainy season, we recommend intensified VL control measures before and during this season to reduce the risk of disease transmission
