Data from: Honey bee (Apis mellifera) sociability and nestmate affiliation is dependent on the social environment experienced post-eclosion

Underpinning the formation of a social group is the motivation of
individuals to aggregate and interact with conspecifics, termed
sociability. Here we developed an assay, inspired by vertebrate approaches
to evaluate social behaviours, to simultaneously examine the development
of honey bee (Apis mellifera) sociability and nestmate affiliation. Focal
bees were placed in a testing chamber, which was separated from groups of
nestmates and conspecific non-nestmates by single-layer mesh screens.
Assessing how much time bees spent contacting the two mesh screens allowed
us to quantify simultaneously how much bees sought proximity and
interaction with other bees, and their preference for nestmates over
non-nestmates. Both sociability and nestmate affiliation could be detected
soon after emergence as an adult. Isolation early in adult life impaired
honey bee sociability but there was no evidence for a critical period for
the development of the trait since isolated bees exposed to their hive for
24 hours when as old as 6 days still recovered high levels of sociability.
Our data show that even for advanced social insects, sociability is a
developmental phenomenon and experience-dependent.
