Communication chimique et régulations sociales dans la colonie d'abeilles (Apis mellifera L.) Inra
Maisonnasse, A..
La colonie d’abeille (Apis mellifera L.) est une société complexe où les individus interagissent entre eux, notament par le biais de phéromones. L’étude de cette communication chimique est indispensable à la compréhension des régulations sociales mises en place dans la colonie. Chez l’abeille, plus de 50 substances chimiques avec des effets incitateurs ou modificateurs sur la colonie ont été identifiées. Malgré ces découvertes, de nombreux travaux sont à accomplir pour mieux comprendre ce système de communication particulier.La problématique de cette thèse vise à caractériser l’histoire de vie d’une phéromone majeure l’Oléate d’Ethyle (EO), qui permet d’optimiser l’équilibre nourrices / butineuses dans la colonie. Parallèlement, d’autres recherches ont été...

E-beta-Ocimene, a volatile brood pheromone involved in social regulation in the honey bee colony (Apis mellifera) Inra
Maisonnasse, A.; Lenoir, J.C.; Beslay, D.; Crauser, D.; Le Conte, Y..
Background: In honey bee colony, the brood is able to manipulate and chemically control the workers in order to sustaintheir own development. A brood ester pheromone produced primarily by old larvae (4 and 5 days old larvae) was firstidentified as acting as a contact pheromone with specific effects on nurses in the colony. More recently a new volatile broodpheromone has been identified: E-b-ocimene, which partially inhibits ovary development in workers.Methodology and Principal Finding: Our analysis of E-b-ocimene production revealed that young brood (newly hatched to3 days old) produce the highest quantity of E-b-ocimene relative to their body weight. By testing the potential action of thismolecule as a non-specific larval signal, due to its high...

E-β-ocimene a new volatile primer pheromone that inhibits worker ovary development in honey bees Inra
Maisonnasse, A.; Lenoir, J.C.; Costagliola, G.; Beslay, D.; Crauser, D.; Plettner, E.; Le Conte, Y..
Dans une colonie d’abeilles sans reine ni couvain, les ouvrières tendent à devenir fertiles etinvestir leur énergie dans la ponte d’oeuf non-fécondés. Afin de maintenir une certainestabilité dans l’organisation de la colonie et prévenir ce détournement de l’investissementénergétique des ouvrières, la reine garantie son statut de seule reproductrice et le couvainaccapare le soin des ouvrières. Pour cela, ils émettent des phéromones peu volatiles. Laphéromone mandibulaire (principalement le 9-ODA) émis par la reine ainsi qu’un mélange de10 esters émis par le couvain. Ces composés permettent une castration chimique partielle desouvrières. Cependant, parmi les deux facteurs de régulation de la maturation ovarienne desouvrières, il semble que la présence de...

New insights into honey bee (Apis mellifera) pheromone communication. Is the queen mandibular pheromone alone in colony regulation Inra
Maisonnasse, A.; ALAUX, C.; Beslay, D.; Crauser, D.; Gines, C.; Plettner, E.; Le Conte, Y..
BackgroundIn social insects, the queen is essential to the functioning and homeostasis of the colony. This influence has been demonstrated to be mediated through pheromone communication. However, the only social insect for which any queen pheromone has been identified is the honey bee (Apis mellifera) with its well-known queen mandibular pheromone (QMP). Although pleiotropic effects on colony regulation are accredited to the QMP, this pheromone does not trigger the full behavioral and physiological response observed in the presence of the queen, suggesting the presence of additional compounds. We tested the hypothesis of a pheromone redundancy in honey bee queens by comparing the influence of queens with and without mandibular glands on worker behavior and...

Pheromones in a Superorganism : From Gene to Social Regulation Inra
ALAUX, C.; Maisonnasse, A.; Le Conte, Y..
Analogous to the importance of hormones in controlling organism homoeostasis, pheromones play a major role in the regulation of group homoeostasis at the social level. In social insects, pheromones coordinate the association of “unitary” organisms into a coherent social unit or so called “superorganism.” For many years, honey bees have been a convincing model for studying pheromone regulation of social life. In addition, with the recent sequencing of its genome, a global view of pheromone communication is starting to emerge, and it is now possible to decipher this complex chemical language from the molecular to the social level. We review here the different pheromones regulating the main biological functions of the superorganism and detail their respective...
