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...

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...
