Bioinsecticides, Environnement et Santé
head: Armel GALLET
The team is interested in the mechanisms of defense of an organism against environmental aggressors and the pathophysiological consequences when those mechanisms failed. Focusing on host-pathogen interactions, we are studying gut physiology, intestinal stem cell functions in the maintenance of cellular homeostasis and innate immunity in Drosophila melanogaster.
Biology of Introduced Populations
head: Elodie VERCKEN
The lab studies the conditions for the installation and the evolution of introduced populations of insects. Our biological models are invasive pests and species used in biological control. Our research on introductions, subsequent demographic and geographic expansions, and the associated evolutive phenomena, is based on ecology and evolutionary biology. We combine behavioural ecology, population genetics and population dynamics.
Community Ecology in Agrosystems
head: Nicolas DESNEUX
The CEA team is questioning the Community Ecology in Agrosystems for fundamental research interests but also in order to improve IPM (Integrated Pest Management) and particularly biocontrol strategies.

Developmental timing, Environment, and Behaviors
head: Nuria ROMERO
Our interest focuses on understanding how does the environment interact with the genes to times the Juvenile-to-adult DevelopmentalTransition (JDT) and its associated behaviors. The JDT (Metamorphosis/ puberty) determines the reproductive ability for a given species. Therefore, uncovering the mechanism timing this developmental transition is essential to improve pest management efficiency but also, in the case of human, to battle against adverse health consequences caused by earlier puberty.

The support team provides outreach service to the research teams and technical units of the ISA unit. Made up of 14 people and placed under the responsibility of the administrator.

Evolution and Specificity of Multitrophic Interactions
head: Marylène POIRIE
The team aims at deciphering the physiological and molecular bases of the specificity of multitrophic interactions involving insect hosts, associated bacterial symbionts, and parasitoid wasps. Our research projects focus for instance on: the insect immune response and how it is possibly modulated by bacterial symbionts, the evolution of virulence factors from venom of Hymenopteran parasitoids, or the role played by extra-cellular vesicles in the transfer of information between host and parasitoid species.

Genomics & Adaptive Molecular Evolution
head: Etienne DANCHIN
The GAME team studies mechanisms of genomic plasticity related to: 1 - species evolution towards a parasitic or pathogenic life style and 2 - adaptation of these same species to current environmental changes, including to methods deployed to manage them.Scientists in GAME use bioinformatics, biostatistics and artificial intelligence for their research.

Project team "Genetics, Environment and Plasticity"
head: Alain ROBICHON
One objective of the team is to use the aphid model to determine the components of epigenetic regulation leading to adaptation to the environment. Our aim is to determine whether epigenetic marks, in particular genome methylation, induced by an extreme climate phase might be heritable across clonality (spring and summer) and also whether this heritability might pass the sexual barrier (fall and winter) to be transmitted in the newly emerged clonal generations the next spring, in order to achieve adaptation.
head: Christine COUSTAU
The management of insect pests, from phytophagous and parasites to disease vectors requires a thorough knowledge of the mechanisms by which insects deal with chemical and biological challenges. These challenges to insect fitness can be viewed as a seamless range of aggressions, rather than categories of "pathogens" or "xenobiotics". The overall goal of our team is to exploit genomic resources to study the functional basis of insect defense mechanisms and their evolution.

Tae Sun MIN
head: Bruno FAVERY and Stéphanie JAUBERT-POSSAMAI
The overall objective of the team, through various levels of study ranging from the gene to the field, is to acquire the scientific basis for a better understanding of the interaction between the plant and the nematode in order to envisage new specific, sustainable and environmentally friendly control methods. The research developed concerns the two partners in the interaction, i.e. the plant, with the study of the development of the disease (susceptibility) or the establishment of resistance, and the parasite, with the analysis of the pathogenicity and its capacity to evolve.

head: Eric GALIANA
The team is currently studying mechanisms underlying interactions between plants and microbes in order to contribute to alternative pest control strategies. Our research programs, mainly conducted on plante-oomycete* interactions, aim at identifying molecular processes that orchestrate, on the pathogen side, the onset and the development of infection and the associated evolutive processes. We also aim at deciphering plant responses, leading to the success (sensitivity) or the failure (resistance) of the infection. We combine plant pathology, cell biology, evolutionary and functional genomics, biochemistry and molecular biology.

Models and Methods for Plant Protection
head: Ludovic MAILLERET
The team aims at making plant protection more respectful of the environment through the development of innovative ecological pest management strategies. For that purpose, the team develops an interdisciplinary research program based on the concerted use of theoretical models and experiments to address specific issues from the individual to populations and agroecosystems.

Research and Development in biological control
head: Xavier FAUVERGUE
The main objective of the team "Research and Development in Biological Control" is the field implementation of biological control strategies against noxious phytophagous insects using entomophagous insects (parasitoids or predators).

Legume-Rhizobium Symbiosis: cellular redox status
head: Pierre FRENDO
The team focuses on improving our knowledge of plant/nitrogen-fixing bacteria (Rhizobium) by studying the role of the cellular redox state during the symbiotic interaction.
