To improvement the fruit quality of the korean raspberry fruit, 3 species of bee, Bombus terrestris, Apis mellifera and Osmia cornifrons were used for pollination in korean raspberry fruit field from Korea. This study was also conducted using 3 kinds of methods for pollination effect, natural condition, net-house and control method. Blooming time of korean raspberry fruit shows always in the middle of the May, foraging behavior of bees used in this examination showed different tendency each other. Especially pollinating time of B. terrestris was 2.73sec and transfer time between flower was 2.64sec. Rate of korean raspberry fruit setting pollinated with B. terrestris, A. mellifera, O. cornifrons were showed 83.1%, 80.5%, 77.5% respectively. And, rate of fruit setting of the untreated control and the control (natural condition pollination) were 36.2% and 76.0%. Therefore, korean raspberry fruit set in the case of B. terrestris compared control was superior to 230%, 109% in contrast to natural pollination showed, A. mellifera and O. cornifrons were no significant difference over natural pollination. The quality of the products of korean raspberry fruit pollinated with B. terrestris showed the highest quality as a result fruit diameter 19.5±0.85, fruit weight 2.7±0.32, sugar content 11.2±1.48 Brix%, seed no. of 86.8±10.15. The rate of productivity increase using the Bombus terrestris was 21% in contrast to natural pollination.
