Actual and predicted growth of colony populations at 2 sites. Colonies were established from package bees (approximately 9000 bees per package) in April. Predicted values were generated from a varroa-honey bee population dynamics model initialized using actual starting colony population sizes of 9000 adult bees and no brood. Monthly averages are +SE. Adult populations did not differ between sites (F1,24 = 2.14, p = 0.16) though the interaction term time × site was significant (F6,19 = 21.8, p < 0.0001). Colonies at the two sites differed in frames of brood (F1,24 = 4.75, p = 0.04)
