Resumo
Two Malaise traps (TOWNES' 1972 model) were installed on an island (lhe "Ilha do Mel") in lhe Bay of Paranaguá, from September, 1988 to August. 1989. at two sites denominated "Fortaleza" and "Praia Grande", for colleetion of insects. At "Fortaleza". 1,715 individuais of Tabanidae were captured, representing 3.20% of all Diptera captured in this site, while at "Praia Grande" 1,420 individuais of the same family were captured, representing 5,06% of ali Diptera captured there. In "Fortaleza", Tabanidae is represented for 10 species, while in "Praia Grande" it is represented for nine species. Dichelacera alcicomis (Wiedemann. 1828) was the most abundant species at two sites, representing 87,52% and 66,69 % of all Tabanidae captured at "Fortaleza" and "Praia Grande", respectively. The grealest number of individuais occurred in November, the month with the lowest relative humidity associated to small pluviometric precipitation, just after a month with high relative humidity associated to a high pluviometric precipilation.
