Abstract
Longevity, duration of hive-bound period, and foraging period, of worker bees, infested or not infested during their pupal development, were investigated during the whole year. Shortening of lifespan depended on the extent of infestation and on season. Influence of infestation on lifespan could be shown during hive-bound and foraging periods; no influence could be shown on flight activity. Drastic differences occurred during winter; in 4 observation hives, only 4–18% of the infested bees that had emerged in September, survived until the following March.This publication has 15 references indexed in Scilit:
