[Blood meals identification of Lutzomyia (Lutzomyia) longipalpis (Lutz & Neiva, 1912) e Lutzomyia (Lutzomyia) almerioi (Galati & Nunes, 1999) by enzyme-linked immunosorbent assay biotin-avidin].
Lutzomyia longipalpis and Lutzomyia almerioi, phlebotomine species from the fauna of Serra da Bodoquena, in the State of Mato Grosso do Sul, Brazil, have been studied, particularly due to the fact of their abundance and occurrence, the Guaicurus settlement, focus of human tegumentary and canine visceral leishmaniasis. In researches that are being carried out in this settlement for identifying the vectors of these parasitosis, 83 engorged females belonging to the species Lutzomyia longipalpis and Lutzomyia almerioi were captured with automatic light traps from 2002 up to 2004 in the peridomiciliary environment of the Guaicurus settlement (hennery). The aim of this study was the investigation on bird feeding habit of females of both the phlebotomine species by the enzyme-linked immunosorbent assay technique, comparing the reactivity during the period from 2002 up to 2004. Of the 57 samples of Lutzomyia longipalpis and 26 of Lutzomyia almerioi that have been tested, 72% from Lutzomyia longipalpis and 96% from Lutzomyia almerioi were reactive, which justifies the feeding habit study in the region as a prevention measure and the institution of an epidemiological survey.
