Prey captured and used in Polistes versicolor (Olivier) (Hymenoptera: Vespidae) nourishment.
The social wasps are predators of many insect species and the study of their preys can reveal the potential of these natural enemies in biological control programs. A total of 240h of collections of preys in 32 nests of Polistes versicolor (Olivier) was carried on in Juiz de Fora, Minas Gerais State, Brazil, from March 2000 to February 2001. The preys captured by P. versicolor were mainly those...
متن کاملSociogenetic structure of Polistes (Aphanilopterus) versicolor Olivier, 1791 colonies (Hymenoptera, Vespidae, Polistini)
The observation of two distinct, well-defined oviposition areas in nests of the primitively eusocial wasp Polistes versicolor suggests the presence of multiple egg-layers and territorial behaviors. Electrophoretic analysis of enzyme loci in pupae from 35 colonies revealed an average observed heterozygosity of 0.10 and the existence of private polymorphisms, thereby indicating a low dispersion i...
متن کاملFoundation Pattern, Productivity and Colony Success of the Paper Wasp, Polistes versicolor
Polistes versicolor (Olivier) (Hymenoptera: Vespidae) colonies are easily found in anthropic environments; however there is little information available on biological, ecological and behavioral interactions of this species under these environmental conditions. The objective of this work was to characterize the foundation pattern, the productivity, and the success of colonies of P. versicolor in...
متن کاملSocial Wasps (hymenoptera: Vespidae) Nesting in Eucalyptus Plantations in Minas Gerais, Brazil
Social wasp colonies can be transferred to agroecosystems in order to control pest populations. Some failures of such transfers are common because wasps may abandon the nest immediately after the colony’s transfer. Knowing the nesting habits of wasps in agroecosystems could improve the success of colony transfer during wasp management. Thus, we recorded social wasp nests in a eucalyptus plantat...
متن کاملSYSTEMATICS, MORPHOLOGY AND PHYSIOLOGY Comparative Analysis of Morphological, Structural and Morphometric Patterns of Polistes versicolor (Olivier) (Hymenoptera: Vespidae) Hypopharyngeal Glands
Using ultramorphological and histochemical techniques, this study describes the structural and morphological patterns of Polistes versicolor (Olivier) hypopharyngeal glands, comparing them with patterns of other Hymenopteran groups. Besides, the presence of intra-specific variation was evidenced by morphometric analysis of the secretory cells in wasps with different ages. The studied species pr...
