The biggest difficulty for beekeepers in the globe is the Varroa mite. So, the honey production and the mortality of adult honeybees are damaged by this pest. Therefore, this study tested some essential oils and chemicals (amitraz), for the control integrated on Varroa destructor and affected of (Apis mellifera L.). Five essential oils (garlic oil,…
Honey bees are important for ecological health, biodiversity preservation, and crop output. Antimicrobials, like Tetracyclines, are commonly used in agriculture, medicine, and beekeeping, bees might be exposed to Tetracycline residues in the environment either directly or indirectly. This study aimed to determine the effect of antibiotic treatment (Tetracycline) effect on the Bio-efficiency of the larvae…
Dear COLOSS colleagues, BeeLife are organising a second online training within the EUBP Platform Project. This time Michael Rubinigg, a Data Scientists specialised in Data Quality Management, will introduce to us to the Best Practices on how to clean data and ensure its easy integration into wider databases. Michael is a biologist, holding a PhD in Plant Physiology, specialised in apiculture, bee health,…
Experiments assessed the comparative efficacy of oxalic acid solution (OA) and combination of formic acid (FA) evaporation and trickling OA to control the honey bee mite, Varroa destructor, at two apiary locations. Queen caging, consecutive OA treatments of broodless colonies, or combined treatments using OA and FA in colonies with brood increased mite mortality (P…
Dear colleagues, For the upcoming SETAC Europe meeting in Dublin (Ireland; April 30th – May 4th) we have initiated a dedicated pollinator session again. Consequently, we want to invite you to contribute to this session (2.11 | New Approaches and Methodologies for the Future Direction of Pollinator Health and Safety) with an abstract for an…
Stingless bees are ecologically and economically important species in the tropics and subtropics, but there has been little research on the characterization of detoxification systems and immune responses within them. This is critical for understanding their responses to, and defenses against, a variety of environmental stresses, including agrochemicals. Therefore, we studied the detoxification and immune…
Egypt has an ongoing long history with beekeeping, which started with the ancientEgyptians making various reliefs and inscriptions of beekeeping on their tombs and temples. TheEgyptian honeybee (Apis mellifera lamarckii) is an authentic Egyptian honeybee subspecies utilized inapiculture. A. m. lamarckii is a distinct honeybee subspecies that has a particular body color, size, andhigh levels…
With an almost global distribution, Varroa destuctor is the leading cause of weakening and loss of honey bee colonies. New substances are constantly being tested in order to find those that will exhibit high anti-Varroa efficacy at low doses/concentrations, without unwanted effects on bees. Lithium (Li) salts stood out as candidates based on previous research.…
In a cage experiment, lithium chloride (LiCl) and lithium citrate hydrate (Li-cit) were tested for varroacidal efficacy and impact on bees. Treatment with Li-cit (4, 7.5, 10, and 25 mM) resulted in 100% varroacidal efficacy and 100% bee survival. Due to better results in the cage experiment, Li-cit was further tested in field experiments on full-sized…
In the European honey bee (Apis mellifera), the olfactory system is essential for foraging and intraspecific communication via pheromones. Honey bees are equipped with a large repertoire of olfactory receptors belonging to the insect odorant receptor (OR) family. Previous studies have indicated that the transcription level of a few OR types including OR11, a receptor…
