The results of using bumble bee and leaf-cutting bee to pollinate soybean male sterile plants in cages were reported in the paper. The results showed that both of them are effective pollinator of soybean male sterile strains. Numbers of pods and seed on a single plant were significantly increased by using these two pollinators. Average pods and seeds per plant were 21.3 and 43.1 respectively in cage releasing bumble bee, whereas in cage releasing alfalfa leaf-cutting bees it was 56.8 and 128.2 respectively. Therefore, alfalfa leaf-cutting bee is a better pollinator for pollinating soybean male sterile plants in cages.
