About the Event
Gard Otis talks about the interconnections between Varroa mites, “winter bees,” and colony mortality.
In the late 1990s, Otis designed studies to find out when winter bees were produced by colonies. He reasoned that for colonies to be relatively strong in spring when brood-rearing commences, survival of winter bees would have to be excellent. Depredation by mites and viruses reduces the longevity of individual bees, thereby weakening or even killing colonies during winter. Therefore, beekeepers should treat their hives with miticides before winter bees are produced.
