Résumé
Surveys of Tabanus in Thailand were carried out in 1975 and 1978. After examination and identification in detail, twenty species were identified. It is concluded that the physiography, agricultural pattern are such that the Thai Tabanus species are concentrated in the north and northeastern parts of Thailand. As a whole, it appears that only Tabanus belonging to the tribe Tabanini are of medical and veterinary importance in Thailand.

The morphological, life-cycle, and experimental studies of Megaselia scalaris were reported. This fly is commonly found both in urban and rural areas in Thailand. It is easily identified and the humped thorax was the most distinct characteristic of the adult. The egg to the adult stage and the life span required 15 to 20 days for the male and 16 to 22 days for the female. Experimental attempts to induce myiasis infection in laboratory animals were unsuccessful.

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.
