To increase the fruit quality and productivity of the apricot, 2 species of insects, Apis mellifer, and Bombus terrestris were used for pollination in apricot field in Yeongcheon province. This study was conducted using 3 kinds of methods for pollination effect, natural condition, net-house treatment and control method. Also this experiment carried out in 2 places, vinyl-house and field condition. In case of field treatment of Apis mellifera, heating lamp experiment was added in net-house to find out the reason for harmful efficacy of low temperature early in the spring. Species of apricot, Mangum, was used in this experiment. A number of foraging activity of Apis mellifera and Bombus terrestris in vinyl-house showed higher than in field condition. But after stoping heating, showed low efficacy after showing peak in 1 PM. In field, Apis mellifera showed peak of foraging activity from 1 to 3PM, heating lamp experiment of field condition showed peak in 3 PM and then lowest tendency to evening suddenly. The fruit set rate of Apis mellifera and Bombus terrestris in vinyl-house showed higher with 92% and 89% respectively than control with 83%. In field, heating lamp treatment of Apis melliferawas was highest with 28% compared to Bombus terrestris with 25% and control with 15%. This results suppose that apricot in field was to be harmed by low temperature and frost in blooming time early in spring
