Winter aggregations, colony cycle, and seasonal phenotypic change in the paper wasp Polistes versicolor in subtropical Brazil
(Springer, 2006-10-01)
Social wasps from temperate zones have clear annual colony cycles, and the young queens hibernate during winter. In the subtropics, the only previously reported evidence for the existence of hibernation is the facultative ...
Nest site selection and flying capacity of neotropical wasp Angiopolybia pallens (Hymenoptera: Vespidae) in the Atlantic Rain Forest, Bahia State, Brazil
(2006-06-07)
In order to evaluate the flying capacity and nest site selection of Angiopolybia pallens (Lepeletier, 1836), we made 17 incursions (136 hours of sample efforts) in Atlantic Rain Forest environments in Bahia state. Our data ...
Structural and functional characterization of two novel peptide toxins isolated from the venom of the social wasp Polybia paulista
(Elsevier B.V., 2005-11-01)
Two novel inflammatory peptides were isolated from the venom of the social wasp Polybia paulista. They had their molecular masses determined by ESI-MS and their primary sequences were elucidated by Edman degradation chemistry ...
Checklist of social (polistinae) and solitary (eumeninae) wasps from a fragment of Cerrado campo Sujo in the State of Mato Grosso do sul
(2013-07-08)
Cerrado is one of the richest biomes in the world but it is still very threatened by human actions that affect not only the flora, but also the fauna, and certainly the largest known group, the insects. We present here a ...
Structure-function relationships of the peptide Paulistine: A novel toxin from the venom of the social wasp Polybia paulista
(2014-01-01)
Background: The peptide Paulistine was isolated from the venom of wasp Polybia paulista. This peptide exists under a natural equilibrium between the forms: oxidised - with an intra-molecular disulphide bridge; and reduced ...
Profiling the peptidome of the venom from the social wasp Agelaia pallipes pallipes
(Elsevier B.V., 2011-09-06)
The wasp Agelaia pallipes pallipes is one of the most aggressive species from the neotropical region, causing many stinging accidents every year, characterized by severe envenoming reactions. The identification of peptides ...
A survey of DNA methylation across social insect species, life stages, and castes reveals abundant and caste-associated methylation in a primitively social wasp
(2013-08-01)
DNA methylation plays an important role in the epigenetic control of developmental and behavioral plasticity, with connections to the generation of striking phenotypic differences between castes (larger, reproductive queens ...
Social Wasp Diversity (Vespidae, Polistinae) in a Forest Fragment in the Northeast of São Paulo State Sampled with Different Methodologies
(California State University, 2010-01-01)
Social wasp diversity in Semideciduous Seasonal Forests of the northeast of São Paulo State is poorly known, causing a lack of information on the diversity of these wasps from these areas which have been degraded. The ...
Influence of the colony cycle on physiological and morphological caste variation in the perennial neotropical swarm-founding social wasp, Protonectarina sylveirae (Hymenoptera, Vespidae, Epiponini)
(2003-08-18)
This paper describes the influence of the colony cycle on caste differences in Protonectarina sylveirae. Despite invariably keeping the main aspects of the conspicuous dimorphism between the castes, it is shown that: 1- ...
