Average honey and pollinating colony profit for treated and untreated Varroa infestations of 2% and 20%, with varying levels of treatment resistance within the Varroa mite population for MAS and non-MAS colonies. Non-MAS colonies are now unable to survive when treatment resistance reaches 50% when faced with a 2% Varroa load, and when treatment resistance reaches 25% with a higher 20% Varroa load. For MAS colonies, as no treatment is necessary at lower Varroa levels, MAS colonies survive regardless of treatment resistance, and with higher Varroa levels, treated MAS colonies are considered unable to survive when treatment resistance reaches 75%.
