Table 1 Hygienic evaluation of the honeybee colonies studied. Hygienic behavior is calculated as a percentage based on the number of dead brood removed in 24 h. Brood were killed by liquid nitrogen

From: Differential gene expression between hygienic and non-hygienic honeybee (Apis mellifera L.) hives

Colony number Hygienic status Dead brood removal in 2011 (%) Dead brood removal in 2012 (%) Mean dead brood removal in 2011 and 2012 (%)
