URBAN BLOW FLIES (DIPTERA: CALLIPHORIDAE) IN FOUR CITIES OF THE COLOMBIAN CARIBBEAN COAST

The purpose of this study was to evaluate the species composition of the family Calliphoridae from samples collected in four different cities in the colombian Caribbean coast. Van Someren-Rydon traps were used baited with human faeces, rotten fish and fermented fruit were used. Six traps were placed in each city (two traps per type of bait), for a total of 24 traps. They were left for 72 hours in each site and samples were collected every 12 hours (day and night). 5654 individuals were identified, belonging to the subfamilies Chrysomyinae and Luciliinae. The identified species were Cochliomyia macellaria, Chrysomya albiceps, Chrysomya megacephala, Lucilia eximia, Lucilia sericata and Chloroprocta idioidea, expanding the range of distribution for the last two species. The best bait was the rotten fish and the best time to collect these species was during daylight.
