Over the past decade, honey bees have experienced a sharp increase in public and scientific interest in the wake of reports on unsustainable population losses and considerable health problems. Many of these studies relate to sublethal stress effects that affect behavior and life expectancy (Perry et...
ethyl oleate is passed from foragers to the in-hive bee population through trophallaxis, together with collected nectar (Leoncini et al., 2004). When a hive consists of an adequate amount of foragers, the strength of their pheromone signal delays the transition of young bees to the forager ...
