We
study two biological models, aphids (we work on several species
which are agricultural pests), and pollinating bees. |
@Bernard Chaubet |
Aphids, through their original biology (with
a peculiar mode of reproduction, alternatively sexual and
asexual) allow to study fundamental problems such as the mechanisms
determining the maintenance or loss of sexuality,
inter-twinned demographic and genetic processes,
and the ecology and evolution of plant/phytophagous
insects/natural enemies interactions. These researches
have also an applied interest, helping to better control aphid
populations and the viral diseases transmitted by aphids. |
The pollinating bees model
comprise several pollinating species (honey bee, bumblebees,
solitary bees) and several insect/plant models. On the cognitive
side, the aim is to better know the rules which govern the
foraging behaviour, in the context of the optimal
foraging theory. On the applied side, we study how
to best favour gene flows (seed production) or how to limit
them (GMO pollen). |

For the study of both models,
we use multidisciplinary approaches including population genetics,
functional genomics, ecology (in particular dispersion/migration),
theoretical biology and modelling. Our activities cover three “aphid” themes
and one “bee” theme: |
