The thermogenic center in social wasps

Journal of Electron Microscopy, 2006
In the social wasps Vespa orientalis and Paravespula germanica (Hymenoptera, Vespinae), a thermogenic center has been found in the dorsal part of the first thoracic segment. The temperature in this region of the prothorax is higher by 6-9 degrees C than that at the tip of the abdomen, and this in actively flying hornets outside the nest (workers, males

Pheromones in Social Wasps

2010
Social wasps need an efficient communication system to coordinate their members in the numerous activities of the colony. In this regard, the chemical channel is the most utilized by social wasps to transfer information in intraspecific (pheromones) and interspecific (allomones) communication.

Visual Recognition in Social Wasps

2015
Social recognition, i.e. the ability to recognize and assign individual membership to a particular and relevant class, such as caste, dominance status, gender or colony, shapes the amazing organization of insect societies. Traditionally, it has been assumed that social recognition in social insects is mainly governed by chemicals.

Sociality in Wasps

2017
Wasps encompass solitary, communal, and facultative, obligate, and swarm-founding social species and are important model organisms for study of the origin and elaboration of insect sociality. Common names for social species are hover wasps, paper wasps, yellowjackets, hornets, and swarm-founding wasps. Excepting a few communal species, all social wasps

Catecholamines in social wasps

Comparative Biochemistry and Physiology Part A: Physiology, 1974
Abstract 1. 1. Various tissues originating from several species of social wasps showed significant amounts of catecholamines (noradrenaline, adrenaline, dopamine and 5-hydroxytryptamine). 2. 2. Dopamine proved to be the most abundant among the catecholamines examined. 3. 3.

DISTANCES, ASSUMPTIONS AND SOCIAL WASPS

Cladistics, 1992
The use of distance data in phylogenetic inference retains adherents in molecular systematics, despite the well-established cladistic critique of distances. Molecular distance matrices have been supposed to measure evolutionary divergence; how- ever, trees based upon analyses of such matrices are generally uninterpretable as doing so-under realistic ...
