Influence of peri-domiciliar environmental conditions in the dispersion and proliferation of phlebotomine sandflies in Parana state, southern Brazil

ABSTRACT

The results of phlebotomine collections with Falcäo light traps are described. The collections were made in an area of the Mururê farm, in the Terra Boa County, Paraná State, south of Brazil. One trap was installed at the border of a modified primitive forest and seven in animal shelters (poultry sheds and pigsties) distant 10 to 600m from this forest. Of a total of 5,122 phlebotomine 4,046 (79 per cent) were caught in an pigsty 10m from the border of the forest. The dominant species was Lutzomya whitmani. Dispersion of phlebotomine was near to 600m from the border of the forest and suggests that good environmental conditions for effective breeding in peridomiciliary areas in Mururê farm were not found, what explains the rare occurrence of tegumentary leishmaniasis there
