 note = {P(論文), A survey of wild bees was conducted in the rural area on Yaku-shima, Kagoshima Pref, southern Nippon (lat: 30°14'-28', alt: 0-200 m) in 1982 and 1983. In total 47 species of bees, represented by 1,215 individuals and belonging to 20 genera in 6 families, were collected by 8 times of sampling, each spending 3 days. The descending order of the families in which involved a large number of species and individuals were as follows: Halictidae (17) > Anthophoridae (10) > Megachilidae (8) > Andrenidae (6) > Colletidae (5) > Apidae (1, excluded Apis), and Halictidae (534 individuals) > Colletidae (416) > Anthophoridae (95) > Megachilidae (84) > Andrenidae (73) > Apidae (13, excluded Apis). The 6 dominant species in descending order were Halictus aerarus> Hylaeus hirashimai > Hylaeus insularum > Lasioglossum occidens > Amegilla florea > Lasioglossum (Evylaeus) sp. 1. The first 2 species occupied 37.7% (458/1,215) in numbers among the total number of bee individuals collected. These aspects were discussed comparing with results obtained in other areas such as Shiroyama Park in Kagoshima-shi and Sosanji in Miyazaki-shi, southern Kyushu. Phenologic curves in the number of both species and individuals showed 2 conspicuous peaks at early summer and early autumn, of which the former occupied by Halictidae and Colletidae and the latter by Halictidae. In phenologic curves of the predominant species, Halictus aerarius showed the long-termed flower-visiting activity in nearly all season, and the other 3 species also, excluded L. (E.) sp. 1, showed the long-termed flower-visiting activity comparatively. Flowering plants visited by bees were 65 species in 27 families. About 53% of total bee individuals were collected on Umbelliferae, Euphorbiaceae and Compositae. Discussion was made on the characteristic of flower-visiting habits in each bee families and the predominant bee species.},
