Rear declining bumblebees in captivity
In experiments in South Korea with 132 field-caught, naturally hibernated B. ignitus queens, Yoon et al. (2002) found 27°C and 65% relative humidity produced higher rates of colony foundation and better colony performance than other temperatures and levels of humidity. Queens were confined alone to induce colony formation. At 27°C, 83% of queens founded colonies, 63% produced colonies with more than 50 workers and 46% produced new queens. These percentages were 2.2-5.5 times higher than rates achieved at 23° and 30°C. Colonies reared at 27°C produced more workers and more queens than those at other temperatures, and developed two to five times faster.
