The CRCA-CBI hosted the 31st french IUSSI congress!

From 28 to 30 August, the CRCA-CBI hosted the 31st conference of the French section of the International Union for the Study of Social Insects.

Around a hundred people from France, Belgium, Spain and Switzerland came together to present and discuss their latest findings on the biology and ecology of social insects (ants, termites, bees, hornets, wasps and bumblebees).

Creation of a new team at the CRCA !

The “BeeAntCE” team, Navigation and Cognitive Ecology, is interested in the study of cognition in an ecological, evolutionary and embodied context through one of the most impressive cognitive tasks in the animal world: insect navigation.

They officially started their activities on January 1, 2023.

We wish them great success!

Abel Bernadou joins the CRCA as a professor !


Using ant societies as a study model, his research project aims to identify the physiological, behavioral and ecological determinants that predict the formation of reproductive hierarchies and the emergence of division of labor in animal societies.

Renaud Bastien joins the CRCA as a CNRS researcher !


To produce a response adapted to their environment, animals must perceive and integrate the information contained in it. Vision, in particular, is crucial in many species to directly acquire spatial information. Renaud will study how the information contained in the visual field is integrated by the individual to control its movement.










Crowdfight COVID-19

As part of the fight against Covid-19, researchers from the CRCA – CBI Toulouse have set up the Crowdfight COVID-19 platform, with the aim of putting the skills of researchers not mobilized on Covid-19 at the service of mobilized researchers.


Congratulations to Aurore Avarguès-Weber !

Aurore Avarguès-Weber, researcher at the CRCA-CBI, was awarded the CNRS Bronze Medal last night for her work on bee cognition.

This distinction rewards the first works of researchers who are specialists in their field. It also represents an encouragement by the CNRS to pursue well initiated and already fruitful research.

CRCA congratulates Aurore on this great award !
