Avaliação de medidas de controle de flebotomíneos no Município de Lobato, Estado do Paraná, Sul do Brasil

Abstract

Sandfly control measures were evaluated at the Da Barra Ranch, Lobato municipality, Paraná State, Brazil. The insects were captured with Falcão traps in houses, a cattle corral, and a forest area from July to November 1999 and from February to June 2000. In December 1999 and January 2000 the following measures were taken to decrease the sandfly density in peridomiciliary areas and domiciles: (i) screens were placed on windows of buildings (domiciles, dormitory, cafeteria); (ii) all organic material was cleaned from the peridomiciliary area; and (iii) buildings were sprayed for insects. There were more Nyssomyia whitmani, Pintomyia fischeri, P. monticola, and Brumptomyia brumpti specimens in the former period, while N. neivai, Migonemyia migonei, and N. pessoai predominated in the latter. In the initial period most of the sandflies were captured in the forest and in the latter period in the houses. The sandfly control measures did not reduce the sandfly population on the Da Barra Ranch, but they led to significant proportional changes in the insect fauna composition.
