Abstract

We carried out a year-long survey of insects, using carrion-baited traps in the municipality of Campinas and five surrounding municipalities with different urbanization profiles, insoutheastern Brazil. We studied the spatio-temporal variability and preferences for type of bait of three blowfly species that are forensically important in Brazil: Chrysomya albiceps (Wiedemann),Chrysomya megacephala (F.), and Lucilia eximia (Wiedemann). All three species preferred chicken. C. albiceps and L. eximia preferred the urban environment, while C. megacephala preferred the rural environment. Calliphoridae, Muscidae, Fanniidae, and Sarcophagidae were the most numerous families. No clear seasonal patterns could be recognized for the three species. The associations ofspecies/municipality, species/environment, and species/bait are discussed from the ecological andforensic standpoints. (AU)
