The declining diversity of pollinating insects is a major threat to ecosystem conservation, pollination services, and global food security. Honeybees dominate managed pollination, but their dominance can affect other pollinators. Competition for resources lead decreased foraging success survival rates wild bees, especially bumblebees. This study explores the dietary composition honeybees bumblebees using molecular metabarcoding techniques with three primers (ITS2, TrnLgh, TrnLch) in an...
In this study, we evaluated the impact of supplementing honey bee feed with molybdenum-based compounds. Among a dozen dinuclear Mo(V) complexes, first selected most stable and non-toxic which were tested as food supplements in an extensive eight-year campaign involving more than 700 beehives across various environmental conditions Moldova, France, Greece USA. This unprecedented field revealed that few milligrams compounds Na-Mo2O4-EDTA or Li-Mo2O4-EDTA provided spring autumn, increased queen...
The presence of the Varroa destructor mite requires use acaricide treatments for honeybee colonies. Amitraz is one most common acaricide-active ingredients used by beekeepers. Certain populations have developed resistance to amitraz, thereby leading a loss in efficacy amitraz-based treatments. Two products, Apivar and Supatraz, were applied same apiary France evaluate their efficacy. Both are but different galenics. Thanks field data, dynamic model was simulate actions Supatraz on...
Abstract BACKGROUND Varroa destructor is a parasitic mite of the honey bee, Apis mellifera . Its presence in colonies can lead to collapse within few years. The use acaricides has become essential manage hive infestation. However, repeated and possibly incorrect acaricide treatments, as tau ‐fluvalinate, led development resistance. vitro phenotypic test allows proportion susceptible or resistant individuals be known following an exposure active substance. In mites, resistance ‐fluvalinate...
Varroa destructor is a parasite of honeybees. It causes biological damage leading to the colony collapse in absence treatment. In recent years, acaricide resistance has emerged mites, decrease treatment efficacy. We modelled action Apivar (amitraz) treatment, using three input parameters: duration, period, and daily mortality due The output parameters were cumulative mite during residual number efficacy, expressed as percentage.The model was validated by monitoring efficacy field, 36 treated...
Honey has been employed for the treatment of wounds and diseases ancient time, thanks to its antimicrobial curative properties. This study aims present biochemical characteristics, including amount sugar, total phenols, phenolic chemicals, antioxidant properties, antibacterial activities a specific type French honey (Sologne summer forest) in comparison with manuka honey. According our findings, Manuka tested 23% fewer polyphenols than Sologne forest The results showed that had different...
Bees have long been used as a bioindicator of environmental quality. They the capacity to bio-accumulate various pollutants in cities such PAHs and heavy metals, but they are also very sensitive other rural areas pesticides. The lethal sub-lethal impacts pesticides on bees extensively studied. However, studies often focus single molecule at same time rarely cocktail oxidant stress response metals NOx was measure, no were engaged impact honeybees. aim this study measure oxidative chronic...
The presence of the mite, Varroa destructor, requires use acaricide treatments in most honeybee colonies. Amitraz is one common substances used by beekeepers. Some mite populations have developed resistance to amitraz leading a loss efficacy amitraz-based treatments. Two products, Apivar and Supatraz were applied same apiary. Both are but different galenics. Thanks field data, dynamic model was simulate action on population. We consider two parameters compare products: daily mortality rate...
