Summary. A numerical model has been developed to calculate the total number of transits in each worker foraging category for the 170 days of development of a successful colony. Seven categories of workers are considered: two of outgoers (earth carriers and non-earth outgoers), and five of incomers (pulp, flesh, full fluid, and partial fluid carriers, and empty incomers). The model allows for variation...
Thirteen days of foraging studies, on normally developing colonies of Vespula vulgaris, were carried out between 5 July and 7 October over several years. Seven categories of workers were considered: two of outgoers earth carriers and non-earth outgoers, and five of incomers pulp, flesh, full fluid, and partial fluid carriers, and empty incomers. The pre-exponential small-cell colony is characterised...
