I think it appropriate to remark once again that one must consider wind
direction, since odor molecules (including noxious substances) can drift
only downwind. The maximum "scare distance" downwind from a colony is only
a few hundred meters; see the following reference:
1973. The search dynamics of recruited honey bees, Apis mellifera
ligustica Spinola. Biol. Bull. 144:107-131.
In our climate wind patterns are nearly completely predictable during
summer months, making our observations more reliable than in other areas
where winds are more variable.
