Summary of "What can a non-eusocial insect tell us about the neural basis of group behaviour?"

Group behaviour has been extensively studied in canonically social swarming, shoaling and flocking vertebrates and invertebrates, providing great insight into the behavioural and ecological aspects of group living. However, the search for its neuronal basis is lagging behind. In the natural environment, Drosophila melanogaster, increasingly used as a model to study neuronal circuits and behaviour, spend their lives surrounded by several conspecifics of different stages, as well as heterospecifics. Despite their dynamic multi-organism natural environment, the neuronal basis of social behaviours has been typically studied in dyadic interactions, such as mating or aggression. This review will focus on recent studies regarding how the behaviour of fruit flies can be shaped by the nature of the surrounding group. We argue that the rich social environment of Drosophila melanogaster, its arsenal of neurogenetic tools and the ability to use large sample sizes for detailed quantitative behavioural analysis makes this species ideal for mechanistic studies of group behaviour.

The evolution of large insect societies is a major evolutionary transition that occurred in the long-extinct ancestors of termites, ants, corbiculate bees, and vespid wasps. Researchers have long used...

Telomerase activity is upregulated in the fat bodies of pre-diapause bumblebee queens (Bombus terrestris).

The attrition of telomeres, the ends of eukaryote chromosomes, and activity of telomerase, the enzyme that restores telomere length, play a role in the ageing process and act as indicators of biologic...

Feedback loops in the major evolutionary transition to eusociality: the status and potential of theoretical approaches.

In this review, we adopt a step-wise framework for the evolution a major evolutionary transition in light of eusocial insects. By focusing on the sequence of (1) group formation, (2) alignment of gene...

Medical and Biotech [MESH] Definitions

A term used in Eastern European research literature for the functional neural unit that provides the basis for differential sensitivity; the analyzer consists of receptor, afferent nerves, and their central connections. (From Campbell's Psychiatric Dictionary, 8th ed.)

An early embryonic developmental process of CHORDATES that is characterized by morphogenic movements of ECTODERM resulting in the formation of the NEURAL PLATE; the NEURAL CREST; and the NEURAL TUBE. Improper closure of the NEURAL GROOVE results in congenital NEURAL TUBE DEFECTS.

Free-standing or supported light weight meshwork fabric made of cotton, silk, polyester or other material having openings too small to allow entry of mosquitoes or other insects, thereby protecting against INSECT BITES; INSECT STINGS, and insect-borne diseases.

A genus of insect in the mealybug family Pseudococcidae.

The genetic complement of an insect (INSECTS) as represented in its DNA.
