The effects of high or low pollen storage on Apis mellifera L. brood removal behavior and Varroa jacobsoni reproduction were examined. High pollen storage colonies removed 49% of the infested
larvae compared to 33% removal by the low pollen storage colonies. No difference was found in the
proportion of fertile mites between those reared in high or low pollen storage colonies, although mite
fertility appeared to decrease from mid to late summer in British Columbia, Canada. These findings
indicate that the presence of pollen stores increases the rate of cell removal, and warrants further
investigation into colony management as a potential means of V. jacobsoni infestation control.
