Resumen:
Vespula germanica is a social wasp that efficiently exploits food resources.Odor cues, derived from substances located in wasp heads, have been provedto be central in conspecific attraction in this species. However, it remains unknownwhether this attraction is related to foraging or defense responses. Inthis study we analyze conspecific attraction under two different contexts: atthe nest entrance (defense) and under foraging conditions. We also test waspresponse with two dosages of head extract and crosschecked the attractivenessof extracts obtained from different populations. We found no evidenceof alarm response to head extracts either at the nest entrance or under foragingconditions. Moreover, no differences in attractiveness were found toboth doses tested. Head extracts attract similarly in the same or a differentpopulation suggesting that conspecific attraction is not restricted to colonynestmates.
