bees Apis mellifera Linnaeus 1758 and Trigona spinipes Fabricius 1793 (Piedade-Kiill and Ranga, 2000).
Colony size seems to be related to several of features that characterize these eusocial
Not only eusocial
insect colonies but also most parasocial and subsocial groups should be designated as societies and their members as social in the most general sense."
For gregarious and eusocial
insects, communication relies essentially on chemical signals and amplification mechanisms (Camazine et al., 2001).
That possibility occurred to Sean O'Donnell at the University of Washington in Seattle when he studied one of the so-called eusocial
wasps, Polybia occidentalis.
Genetic relatedness and population structure in primitively eusocial
wasps in the genus Mischocyttarus (Hymenoptera: Vespidae).
Relatedness and population structure of the primitively eusocial
bee Lasioglossum zephyrum (Hymenoptera: Halictidae) in Kansas.
Polistes is a large, cosmopolitan genus of eusocial
wasps, and like other social vespids, its members can create environmental problems when introduced to novel environments.
However, the characterization of the molecular mechanisms underpinning cooperative behaviour has been mainly restricted to highly evolved social organisms that are study models in their field: e.g., the honeybee Apis mellifera, for social insects.In this project I will adopt a novel approach to understand cooperative behaviour in two social insects that have evolved different levels of sociality: the primitively eusocial
paper wasp Polistes dominula and the highly eusocial
fire ant Solenopsis invicta.
In other words, apart from establishing nests in various semi-natural habitats surrounding fields, some bee species (e.g., eusocial
bees) managed to establish their nests in hallows of living trees, meaning that one should know these tree species and maintain them in the farm-landscape to increase nesting sites opportunities of good pollinators living within agricultural matrices.
Para la estimacion de la abundancia de especies de hormigas se debe tener en cuenta que las hormigas presentan comportamiento eusocial
y esto introduce sesgos al estimar la abundancia relativa como numero de organismos colectados, ya que una colonia puede estar cerca de una trampa y ser colectada parcial o totalmente.
In the classic definition of degrees of social behavior by Wilson (1971), eusocial
species are characterized as having members of the same generation using a composite nest, cooperation in brood care, overlap of generations with offspring assisting parents and reproductive division of labor.
