[Lutzomyia whitmani periurbanization in a focus of cutaneous leishmaniasis in the State of Maranhão, Brazil].
An entomological survey was performed in the periurban area of the municipality of Dom Pedro in the state of Maranhão in 2000, in order to estimate the abundance of Lutzomyia longipalpis, due to the occurrence of one suspect death caused by kala azar. However, it was surprisingly verified that 82.4% (2,440 specimens) from the total of 2,961 sand flies captured in the peridomicile were Lutzomyia whitmani. This association has indicated a new pattern for cutaneous leishmaniasis transmission (urban), as has been observed with regard to kala azar in the northeast of Brazil.
