Abstract: Objective To investigate the infestation of flies in residential areas in China, 2019, and to provide a reference for sustainable fly control. Methods The data of flies captured by the cage trapping method were collected from the national fly surveillance system in China, 2019, and the density and seasonal fluctuation of various fly species were compared between different habitats or provinces. Descriptive methods were used for statistical analysis. Results Among the fly species captured in 2019, Musca domestica (1.31 flies/cage), Lucilia sericata (0.83 flies/cage), species from Sarcophagidae (0.82 flies/cage), and Muscina stabulans (0.53 flies/cage) had the highest densities. Farmers' markets had the highest total fly density (5.78 flies/cage). The peak of total fly density occurred from June to August. Among the dominant fly species, M. domestica, L. sericata, and species from Sarcophagidae had similar seasonal fluctuation trends to that of the total fly density. Conclusion The fly surveillance data in 2019 suggest that M. domestica is still the dominant fly species in residential areas in China, with its peak period in June to August, and the most affected habitat is farmers' market.
