TRAFFIC THROUGH THE NEST ENTRANCE OF A COLONY OF VESPULA ARENARIA (HYMENOPTERA: VESPIDAE)

Abstract
Statistical analysis of traffic data at the nest entrance of a colony of the yellowjacket, Vespula arenaria (F.), showed no evidence for the operation of social facilitation of the type described by Blackith (1957). As in bumble bees, the appearance of contagion in the temporal distribution of exits and sorties is the result of overall change in flight activity and is not due to social interaction between wasps.
