Abstract

국내 및 국외 뒤영벌 생산업체의 서양뒤영벌(Bombus terrestris) 산란율, 봉군형성률, 신여왕출현 봉군율 등 봉세발달 및 인공월동 후 생존율을 비교 조사하였다. 국내 3개와 국외 1개 생산업체의 창설여왕벌 봉군에서 생산된 일벌수는 232.4-270.8마리, 여왕벌수는 62.0-181.8마리로 다소의 차이는 있었으나 국내 및 국외 뒤영벌 생산업체간에 유의성은 없었다. 업체별로 생산된 여왕벌을 탄산가스처리후 사육한 결과, 산란율, 봉군형성률, 신여왕출현봉군율 등 봉세발달은 국내업체에서 생산한 서양뒤영벌이 유럽산보다 우수한 것으로 나타났으나, 일벌 및 여왕벌수는 유럽산 뒤영벌이 다소 많은 것으로 나타났다. 또한 국내 3개 뒤영벌 생산업체와 유럽 2개 업체에서 생산된 서양뒤영벌을 인공월동하여 사육한 경우에도 다소의 차이가 있었지만, 생존율 및 봉세발달에서 뚜렷한 차이가 없었다. 이와 같이 업체별로 생산된 창설여왕벌과 2세대 여왕벌의 휴면처리를 달리하여 사육한 결과, 국내 및 국외 뒤영벌 생산업체의 서양뒤영벌의 봉세 간에 차이가 없는 것으로 나타났다. We compared colony development and survival rate after artificial hibernation between the bumblebees, Bombus terrestris, produced from domestic and foreign companies. The number of worker and queen produced from foundation colony of three domestic and one foreign companies was 232.4-270.8 and 62.0-181.8, respectively, but there was no statistical difference. In colony development of B. terrestris queens which were terminated diapause by <TEX>$CO_2$</TEX> narcosis at different companies, oviposition rate, colony foundation and progeny-queen production of bumblebees produced from domestic companies were superior to those from foreign company. But foreign company in the number of worker and queen was superior to domestic companies. On the other hand, survival rate and colony development of B. terrestris queens, which were terminated diapause by artificial hibernation at three domestic and two foreign companies, were no significant differences. These results indicate that oviposition, colony foundation, progeny-queen production, and survival rate after artificial hibernation showed no differences between the bumblebees produced from domestic and foreign companies.
