Anecdotal observations from beekeepers
suggest that adult honey bees will ingest sugar
water feed containing OA. We noticed small,
pea-size pools of the OA sugar water solution
on the top bars of several hives up to 6 days
after OA application. We did not observe in-
gestion of the OA solution by adult bees and
the pools eventually evaporated. If the anec-
dotal observation that bees will ingest sugar
water containing OA is true, our results sug-
gest that the concentration must be lower than
3.5% OA by weight. Our results only apply to
the trickle method with a 3.5% OA sugar water
solution (1:1) (w:w).
