초록

We investigated ovary development and sperm productivity at the age after eclosion to secure superior traits of Bombus terrestris. As the results, the ovary of mated queen tends to be slightly more development than that of non-mated queen. In the number of eggs per ovariole and spermatheca size, ovary of mated and non-mated queen was the most developed at 15 days and 20 days after eclosion, respectively. In case of male, the number of sperm of non-mated male was 236 thousand at one day after eclosion, and was highest as 497 thousand at 9 days, and tended to show a dramatic decline at 35 days (87 thousand). The number of sperm of mated male was similar to that of non-mated male, but was 1.1~1,7 times more less. The number of sperms was the highest at 9 days after eclosion. In investigating the number of sperm within spermatheca, the number of sperm within spermatheca of mated queen was 22.5~28.1 times more less than that of non-mated male, and 13.6~24.4 times reduced than that of mated male.
