Brood nest temperature (mean±SD; n=8) of A. mellifera ligustica and A. mellifera sinisxinyuan recorded during the control and heating treatments from April to August 2017. Cumulative data of eight bee hives is presented for each treatment. * indicates significant difference between treatments for each subspecies (two-sample Student’s t-test; p≤0.05).

Daily brood nest temperature of A. mellifera ligustica and A. mellifera sinisxinyuan during ambient (control treatment) and warmer ambient (heating treatment) climatic conditions from April to August, 2017 (cumulative data for 8 bee hives for each treatment). The shaded area indicates the standard deviation above and below the mean represented by the line of the same colour.
