Kwon et al. (2003) found that confining 100 B. terrestris queens with a young male pupa 1-2 days old stimulated egg laying and improved overall colony productivity compared to queens that had been confined with older pupae (9-11 days old). Eighty per cent of the 20 queens given a 1-2 day old pupa produced a colony, compared to 30% of 20 queens given a 9-11 day old pupa.
