Survey of preys captured and used by Polybia platycephala (Richards) (Hymenoptera: Vespidae, Epiponini) [PDF]
Neotropical Entomology, 2005 The social wasps are predators of several species of insects and the study of their preys can reveal their potential for programs of biological pest control. During the period of September 2000 to January 2002, were accomplished 70h of collections of the preys captured in twelve nests of Polybia platycephala Richards, placed in urban areas of Juiz de ...

The division of labor is a central theme in the study of social insects. In bees and wasps, this activity is regulated by age polyethism. Important physiological and morphological changes have been widely studied in the polyethism of honeybee workers. In contrast, this is a relatively unexplored subject in social vespids.

In a previous study, we showed that the Polybia paulista wasp venom causes strong myonecrosis. This study was undertaken to characterize the myotoxic potency of mastoparan (Polybia-MPII) isolated from venom (0.25 microg/microl) and injected in the tibial anterior (TA) muscle (i.m.) of Balb/c mice.

Colonies and nests ofApoica pallens in the llanos region of Venezuela range from small foundress nests to large mature colonies. Nests are sited on small diameter, near-horizontal branches in a variety of shrub and tree species. During the day, adult wasps cluster on the face of the nest in an array that seems to be determined by orientation to gravity;
