Resumo: | A study has been made of the phlebotomine fauna in an area high1y endemic for Leishmania braziliensis braziliensis in forest of the Serra dos Carajás, Pará State, Brazil, using human and rodent bait. A total of 23 different species were encountered, including 2 new sandflies, to be described at a later date. Over 92% of the total catch off man was made up by species of the genus Psychodopygus. Df these, Ps. wellcomei formed 65% of the total caught off man and 24.5% of the total off rodents. This species is of particular interestin view of its tendency to bite man throughout daylight hours. Once more we have confirmed that although Lutzomyia flaviscutellata may be the predominent species feeding on rodents, it is rarely taken biting man. Very few sandflies were captured above ground-level; and attempts to find the .daytime resting places for the major man-biting species were unsuccessful. The relationship of rainfall to sandfly density is discussed. It is concluded that the population density of certain forest species may depend not so much on the quantity of rainfall, but more on the amount of water which persists in the topsoil in a given region. |

Ps. wellcomei representa 65% dos espécimens atraídos pelo homem, e 24 5% dos capturados com isca roedor. Esta espécie tem particular importância, porque é capaz de picar o homem, com avidez, mesmo durante o dia. Mais uma vez confirmamos que Lutzomyia fiaviscutellata é uma espécie altamente atraída pelos roedores, e só raramente pica o homem. Num estudo sobre a distribuição vertical dos flebótomos daquela região, confirmamos que a maior densidade está sempre próxima ao nível do solo. Desconhecemos os lugares de repouso das espécies antropófilas. Concluimos que a densidade populacional de certas espécies silvestres depende mais da quantidade de água das chuvas retida pelo solo, que do próprio volume pluviométrico.Ministério da Saúde.

A study has been made of the phlebotomine fauna in an area high1y endemic for Leishmania braziliensis braziliensis in forest of the Serra dos Carajás, Pará State, Brazil, using human and rodent bait. A total of 23 different species were encountered, including 2 new sandflies, to be described at a later date. Over 92% of the total catch off man was made up by species of the genus Psychodopygus. Df these, Ps. wellcomei formed 65% of the total caught off man and 24.5% of the total off rodents. This species is of particular interestin view of its tendency to bite man throughout daylight hours. Once more we have confirmed that although Lutzomyia flaviscutellata may be the predominent species feeding on rodents, it is rarely taken biting man. Very few sandflies were captured above ground-level; and attempts to find the .daytime resting places for the major man-biting species were unsuccessful. The relationship of rainfall to sandfly density is discussed. It is concluded that the population density of certain forest species may depend not so much on the quantity of rainfall, but more on the amount of water which persists in the topsoil in a given region. |
