This experiment was primarily designed to investigate the insect pollinators frequenting the orchards of apple, pear and peach in the outskirts of Seoul; and Suweon for 2 years from 1975 to 1976. The results are as follows. 1. The insect pollinators for 1975 were classified into 3 orders, 12 families and 28 species. Bees in the order of Apis mellifera and Megachile SPP. were predominant (82%) in apples and peaches, while Diptera (78%) was the most numerous with Eristalis cerealis leading the others in pears. 2. In all, insect pollinators of 5 orders and 17 families were indentified in 1976. Hymenoptera was outnumbered by diptera in pear and peach in Seoul. This relation was inversed in Suweon. 3. The number of insect pollinators per flower was appreciably less than that of Wuweon, only 1/9 in peach. 4. The number of efficient insect pollinators such as bees and syrphidae spp. observed in Suweon was 2 times more than that of Seoul. 5. The activities of insect pollinators were strongly influenced by changes in temperature, thus the number of insects reduced by one third when the temperature was dropped from 19.0∼21.0℃ to 16.5∼17.5℃, and no activities was noted at 16.5∼15.5℃.
