Atividade diária de busca de recursos pela vespa social Polybia occidentalis occidentalis (Olivier, 1791) (Hymenoptera, Vespidae)

Resumo

We have registered data concerning the number of way outs and arrivals of the Polybia occidentalis occidentalis (Olivier, 1791) foragers, type of collected resource, the schedule for each observation, temperature, air humidity and insolation. The glucidic resource collection was the main food collection activity done by colonies of P. o. occidentalis, followed by prey collection and collection of wood pulp for nests construction. There has been well-marked differences between the schedule of food resource collections (9:20 a.m. to 2:20 p.m.) and resources for nests construction (8:00 a.m. to 1:30 p.m.). The intensity of food resources collection by P. o. occidentalis is highly dependent on the, temperature conditions and air humidity. There has been a direct relation between food collection and temperature (glucidic resource r2 = 0,25; p<0,05 and prey r2 = 0,10; p<0,05), and also there has been opposite relation between the
collection of glucidic resource and the humidity (r2 = 0,04; p<0,01).
