EVOLBEE: cognition, reproduction and adaptation in the honeybee

Research aims

Bees are a fruitful research model and a prominent agricultural agent. Although numerous studies have been devoted to these insects in the past, a large part of their behavior and of their evolutionary history are still unknown. Our general objective is to provide a better understanding of the rules underlying bees’ adaptation to their environment and to determine the genetic and nervous bases of their behavior by bringing an evolutionary perspective to these studies. Bees show elaborate cognitive capacities, which could be linked to the adaptation of their central nervous system to the constraints related to foraging in a highly complex environment and to their eusocial biology.

To understand the importance of these adaptations and of their potential evolutionary origin, we study the perception, learning and memory capacities of the bees at both individual and colony levels. We are also interested in pheromonal communication between sexuals, from individual to population levels (male congregations). This research aims to understand potential speciation mechanisms (sexual isolation) between the different species of the genus Apis and between subspecies of A. mellifera. Finally, we carry out research aimed at understanding the risks of and protecting bees against potential dangers such as pesticides or an invasive species, the yellow-legged hornet.
