Controlling varroa mites infesting honeybees (Apis mellifera L.) Using some essential oils and amitraz under colony conditions

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,…

Antibiotic treatment (Tetracycline) effect on bio-efficiency of the larvae honey bee (Apis mellifera jemenatica)

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…

BEELIFE Online training on how to data cleaning and integration

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,…

Pollinator session at SETAC Europe meeting in Dublin

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…

The Insecticide Imidacloprid Decreases Nannotrigona Stingless Bee Survival and Food Consumption and Modulates the Expression of Detoxification and Immune-Related Genes

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…

A Spotlight on the Egyptian Honeybee (Apis melliferalamarckii)

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…

Contact varroacidal efficacy of lithium citrate and its influence on viral loads, immune parameters and oxidative stress of honey bees in a field experiment

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.…
