The breeding places and some habits of tabanid flies concerning with their control were investigated in the mountainous regions of Yamagata and Niigata Prefectures in 1964. The results were as follows : 1. The larvae of Tabanus iyoensis, adults of which are prevalent in the mountainous regions, were found beneath decayed leaves lied thick on bushy ground. 2. The larvae of T. sapporoensis were also collected beneath decayed leaves lied on somewhat watery places. 3. Some knowledges concerning with the breeding places of mountainous tabanids such as Chrysozona rufipennis, Tabanus chrysurus, Silvius matsumurai, etc. were also obtained. 4. Most (93%) of the tabanid larvae collected from rice fields were identified with those of Tabanus mandarinus, and others were those of T. takasagoensis, Chrysops van-der-wulpi and an unidentified species. 5. No larvae of bloods sucking tabanids were obtained from sandy soil of river-bank. 6. Tabanid larvae fed on earthworms, Limnodrilus gotoi and Pheretima communissima. 7. Some types of seasonal occurrence were recognized : Chrysops japonicus appeared late in April and vanished early in May, Tabanus fulvimedioides appeared late in June and vanished about the middle of July when many other tabanids began to come out, and Chrysops basalis appeared late in August when the tabanid occurrence declined. Most of tabanids appeared in midsummer, while the occurrence of Chrysops van-der-wulpi and Tabanus amaenus were thought to last long from late in May to the end of August. 8. The tabanids which occurred before the midsummer were thought to appear later and those which occurred after the midsummer earlier in mountains than those on plains, therefore the duration of tabanid occurrence in mountains was observed to be shorter than that on plains. 9. Peaks of occurrence of T. iyoensis, T. mandarinus and T. trigonus were seen at the middle of August. 10. The duration of occurrence of T. iyoensis at the upper stream of Tamagawa River, Yamagata Prefecture, was about a month from late in July to late in August. More than 90% of tabanids collected at their most prevalent period of the middle of August were occupied by T. iyoensis. 11. Most of T. iyoensis were observed to attack cattle and men in the early evening (6.00〜7.00P.m.). 12. T. iyoensis and some other species were observed to be attracted by carbonic acid gas originated from dry ice. 13. Some of T. iyoensis and T. sapporoensis were observed to be attracted by a fluorescent lamp. 14. The cow applied with the repellent (main element : Dimethylphthalate) on body surface was prevented from attack of tabanids.
