The overall objective of SafeAgroBee is to contribute to adaptation and mitigation of the effects of climate change and other drivers negatively influencing the sustainability and the resilience of the agricultural system in the Mediterranean basin, ensuring the income of farmers and food security. In SafeAgroBee we focus on beekeeping and pollinat...
The invasive mite Varroa destructor is identified as the main biotic cause of European honey bee colony losses in many regions, leading to systematic treatments of colonies every year in order to prevent colonies from collapsing. However, some colonies have been reported to survive in the absence of treatment. The ability of honey bee colonies to s...
The mite Varroa destructor is an ectoparasite and has been identified as a major cause of worldwide honey bee colony losses. The use of yearly treatments for the control of varroosis is the most common answer to prevent collapses of honey bee colonies due to the mite. However, the number of effective acaricides is small and the mite tends to become...
Background: The ectoparasitic honey bee mite Varroa destructor is one of the main causes related to the gradual decline of honey bees Apis mellifera. Nowadays, beekeepers utilize a wide range of different synthetic acaricides, organic acids and essential oils to keep mite populations under control. A previous work had shown that pirimicarb could b...
L’acarien Varroa destructor est l’un des principaux responsables de l’effondrement des colonies d’abeilles domestique Apis mellifera. L’arsenal thérapeutique disponible pour lutter contre ce parasite ubiquiste apparait insuffisant à ce jour. Dans le cadre de cette thèse, la démarche de drug design, généralement utilisée en santé humaine, a été appl...
We need a reference standard for the measurement of honey bee head acetylcholinesterase inhibition
The overall objective of SafeAgroBee is to contribute to adaptation and mitigation of the effects of climate change and other drivers negatively influencing the sustainability and the resilience of the agroecosystems in the Mediterranean basin, ensuring the income of farmers and food security. In SafeAgroBee we focus on beekeeping and on pollination services provided by both Apis and non-Apis bees as important drivers in ruling food security, biodiversity, and human well-being. To this aim, SafeAgroBee will specifically address the following points: 1) examine the resilience of bee pollinators (Apis and non-Apis bees) in a changing environment and their capacity to ensure pollination services and crop productivity. For that, we will evaluate Apis and non-Apis bee contribution to the pollination of key crops in the Mediterranean basin (e.g. apple, oilseed rape) along a combined gradrient of climate and honey bee densities to assess synergetical effect among pollinators that maximize pollination services to crops and honey production, in order to derivate integrated management practices that improve food production and safeguard biodiversity in agroecosystems; 2) investigate the adaptability of local bee populations and the application of optimal practices under climate change in order to ensure sustainable beekeeping: Several local genotypes will be tested in different environmental conditions and their performance will be monitored; special traits responsible for disease resistance will also be evaluated; 3) support the development of mitigation strategies ensuring the health of the bees and provide advice for the beekeepers: Organic versus conventional farming strategies and technological beekeeping practices as well as the use of gut microbiota to fight contagious deseases will help to establish different scenarios on adaptation and mitigation measures to be delivered to beekeepers; 4) develop innovative monitoring tools and precision apiculture systems for advanced data acquisition; improve capacity building of the existing innovative systems for data aquisition as well as developing a platform, as ‘Knowledge Hub’ for data analysis, data sharing and eventually data utilization by all stakeholders; 5) develop, test and validate a set of modelling tools supporting sustainable beekeping. This includes, models for evaluating the interactions among landscape, wild bees and managed bees (e.g. landscape pollination requirement and pollination provision by bees), and models for predicting the health status and potential productivity of bees (e.g. honey production); 6) adopt a Citizen Science approach to interact and collaborate with all stakeholders (beekeepers, farmers, advisors, policy makers) and the citizens.
