Quantitative description of calliphorid dipterans captured on the Campus of the Federal Rural University of Rio de Janeiro using sardine bait

Resumo

Quantitative description of the species Chrysomya megacephala (Fabricius), C. albiceps (Wiedemann), C. putoria (Wiedemann) and Cochliomyia macellaria (Fabricius) (Diptera: Calliphoridae) are present according to month of collection. Collections were performed in two areas of the Campus of the Federal Rural University of Rio de Janeiro) from August 1993 to July 1994. Three traps baited with 100 g fresh sardines were used in each of two areas. The bait was left exposed for 168 hr and five successive collections were performed per week for three weeks per month. We collected a total of 69,690 muscoid; 64.74% were dipterans calliphorid. Chrysomya megacephala was the most frequent (40.7%) and presented a sampling peak in November. Chrysomya albiceps (25.9%) was more abundant in April; Cochliomyia macellaria (24.3%) presented two sampling peaks, one in
October 1993 and the other in July 1994. Only 60 specimens of C. putoria were collected during the year of study.
