title: A survey of houseflies in bangkok and neighboring provinces.
abstract: A survey of flies in Bangkok and neighboring province revelaed that among 8,675 flies collected there were 10 genera and 18 species of flies, eg. Musca domestica, M. bezzii, M. conducens, M. nebulo, Chrysomyia megacephala, C. rufifacies, Phaenicia sericata, P. cuprina, Sarcophaga ruficornis, S. peregrina, S. orchidae, S. albiceps, Megaselia scalaris, Lispe orientalis, Anaclysta flexa, Morellia hortensia, Hemipyrellia ligurriens and Orthellia coeruleifrons. Musca mostly bred in low-protein content media, eg., garbage piles of vegetable and rice, and was predominant in the morning while Chrysomyia and Phaenicia mostly bred in high-protein content media, eg., animal carcasses, and were predominant in the afternoon. Female flies were bigger than male and they were more predominant than males in or around breeding places. The density of flies was correlated with the relative humidity but not with rainfall or temperature. The density of flies was correlated with the occurrence of gastrointestinal diseases. Some cases of myiasis have been reported from Thailand.
