Honey bee populations are currently experiencing serious losses, notably in Northern America and Europe, which is a fundamental issue regarding the maintenance and the biodiversity of natural and agricultural ecosystems. The origin of this decline is likely multifactorial because honey bee colonies are facing a multitude of stressors (parasites, xenobiotics, lack of nutritive resources…). Given the diversity of those stressors, there is a need to characterize and better understand the physiological processes involved in general stress responses, in order to ultimately improve the stress resilience of bees.
Recently, a new role for allatostatins in honey bee stress response has been discovered by J.-M. Devaud et al (Research Center on Animal Cognition, Université Paul Sabatier, Toulouse, France). Due to their properties, these peptidic neurohormones are likely involved in the regulation of stress response. The goal of the PhD project will be to further understand the role of allatostatins and their receptors in the control of stress response and resilience in bees. This will be done by using different molecular, physiological and behavioral approaches.Application deadline: 15th September 2013. For more information please see the attached pdf file below.
