Calyptrate diptera (Muscidae and Anthomyidae) of the state of Rio de Janeiro: I. Synanthropy

The synanthropy of Muscidae and Anthomyidae was studied in three ecologically distinct areas of the metropolitan region of Rio de Janeiro. Using baits such row fish, decomposing bovine liver, fresh human faeces and mashed banana it was found that Synthesiomyia nudiseta, Atherigona orientalis, and Musca domestica are highly synanthropic in contrast with Neomuscina pictipenis, Phaonantho devia and Morellia maculipenis found exclusively in the forest.
