Given the physical mode of action, resistance to sugar dusting is not possible. In the 'good 'ol days' it was far easier to start a bee colony and keep them alive than today. Sugar dusting. Examples of mechanical controls include drone brood sacrifice (varroa mites are preferentially attracted to the drone brood), powdered sugar dusting (which encourages cleaning behaviour and dislodges some mites), screened bottom boards (so any dislodged mites fall through the bottom and away from the colony), brood interruption and, perhaps. Dusting With Sugar Dusting the bees with powdered sugar will cause the bees to clean themselves and each other.

Examples of mechanical controls include drone brood sacrifice (varroa mites are preferentially attracted to the drone brood), powdered sugar dusting (which encourages cleaning behavior and dislodges some mites), screened bottom boards (so that any dislodged mites fall through the bottom and away from the colony), brood interruption and, perhaps, downsizing of the brood cell size. Supposedly, the powdered sugar encourages bees to groom themselves and each other, thereby clearing away some of the mites.

Simulation of sugar dusting against varroa Knowing the intrinsic rate of reproduction of the honey bee colony and of varroa, the proportion of mites that are phoretic at the time, and the efficacy of a powdered sugar dusting at removing those phoretic mites, one can create a spreadsheet that will calculate the estimated effect of repeated sugar dustings. It is important to note that the Powdered Sugar Roll Test is not the same as dusting for mites and then counting bodies on the bottom board. Some experts believe that counting mites on the witness board is not an accurate indication of the level of infestation but Larry considers the intrusive sugar or alcohol tests to be an irritant to the colony, a risk of harming the queen and, perhaps most importantly, a demanding task that most beekeepers just don't get done on a timely enough basis to effectively control the mites.
