Neonicotinoids and Varroa mites force the extending of longevity in a bee colony during overwintering to forget.

ABSTRACT: A mathematical model that can estimate the apparent longevity of bee-colony proposed previously clarified the following normal seasonal changes in longevity: The longevity remains almost constant from late April to late September in 20-30 days, after which it continues to extend until the end of wintering, reaching 160-200 days. Just after overwintering, the longevity is shortened almost vertically from one sixth to one tenth. Such normal seasonal changes in longevity are shown when a pesticide-free food is administered to the bee-colony and when pesticide-containing sugar syrup is. However, abnormal seasonal changes in longevity, which does not extend even if winter approaches, are shown for the bee-colony ingesting neonicotinoid-containing pollen and for the colony infested with Varroa m
