Worker honey bees, Apis mellifera, are able to discriminate between co
mbs on the basis of genetic similarity to a learned comb. The nestmate
recognition cues that they acquire from the comb also have a genetica
lly correlated component. Cues are acquired from comb in very short ex
posure periods (5 min or less) and can be transferred among bees that
are in physical contact. Gas chromatographic analysis demonstrates tha
t bees with exposure to comb have different chemical surface profiles
than bees without such exposure. These results support the hypothesis
that comb-derived recognition cues are highly important in honey bee n
estmate recognition. These cues are at least in part derived from the
wax itself, rather than from floral scents that have been absorbed by
the wax. (C) 1995 The Association for the Study of Animal Behaviour
