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.

Eight localities were selected as representative sites to survey the entomofauna of Paraná State, Brazil: 1) Antonina (Sapitanduva); 2) Sao José dos Pinhais (Serra do Mar); 3) Colombo (Embrapa); 4) Ponta Grossa (Vila Velha); 5) Telêmaco Borba (Reserva Biológica Klabin); 6) Jundiaí do Sul (Fazenda Monte Verde); 7) Guarapuava (Santa Clara) and 8) Fênix (Reserva de Vila Rica). Floristic and meteorological conditions in these sites were registered and compared. One Malaise and one light trap were installed in each site. The insects were collected during two years, from August 1986 to July 1988. Only the material obtained during the first year has been sorted at insect order level and analyzed. The quantitative faunistic data were transformed in percentages and monthly densities for the analysis. Comparisons among collecting sites were established based on the faunistic and climatic data. The following methods were used to analyze the data: Clustering Analysis, Principal Coordinate Analysis and the Linear Correlation Coefficient.
