| 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... |

| 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... |

| Nosema ceranae, a microsporidian parasite originally described in the Asian honey bee Apis cerana, has recently been found to be cross-infective and to also parasitize the European honey bee Apis mellifera. Since this discovery, many studies have attempted to characterize the impact of this parasite in A. mellifera honey bees. Nosema species can infect all colony members, workers, drones and queens, but the pathological effects of this microsporidium has been mainly investigated in workers, despite the prime importance of the queen, who monopolizes the reproduction and regulates the cohesion of the society via pheromones. We therefore analyzed the impact of N. ceranae on queen physiology. We found that infection by N. ceranae did not affect the fat body... |
