Introduction Since the Industrial Revolution increased international trade and human movements have resulted in the accidental movement of many species worldwide at an unprecedented level. This ongoing movement of species has brought about the breakdown of biogeographic boundaries that have historically limited the distributions of organisms and some of these species become invasive. Invasive species […]
Introduction Invasive species are among the greatest threats to global biodiversity, playing a key role in the majority of known animal extinctions. In addition to major ecological damage worldwide, biological invasions impose a tremendous cost on society. It is crucial to develop a better understanding of the conditions under which invasive populations are able to […]

L’acarien Varroa destructor est l’un des principaux parasites de l’abeille domestique Apis mellifera, causant d’importantes pertes de colonies à l’échelle mondiale dû à une relation hôte-parasite déséquilibrée. Certaines colonies d’abeilles ont cependant développé des stratégies de défense naturelle face au parasite, ce qui leur permet de survivre à l’acarien. Plusieurs mécanismes de défense ont été […]

POSTDOC: JERUSALEM Diversity in body size underlies two of the organization principles of bumblebee societies: worker division of labor and caste determination, but little is known on the proximate mechanisms regulating body size and how they are socially regulated. This project explores how social cues such as pheromones, behavior, and queen regurgitates, interact with endocrine […]
POSTDOC: UNIVERSITY OF CALIFORNIA, RIVERSIDE The Woodard and Yamanaka Labs in the Department of Entomology at the University of California, Riverside are seeking to recruit a postdoctoral researcher to study bumble bee larval development. The postdoc will use a variety of molecular methods (including but not limited to RNAseq and RNAi) to explore the proximate […]
Depuis son arrivée dans le sud-ouest de la France grâce à l’homme en 2004, le frelon asiatique se répand à travers notre continent grâce aux transports humains. Malgré la possibilité juridique de détruire leur nid depuis 2016, les frelons asiatiques continuent leur expansion. Arrivé en 2004 en France par accident, l’ennemi de nos abeilles se trouve maintenant en […]
