Varroa control (natural treatments)

 

The effects of natural treatments, such as cinnamon and oregano essential oils (EOs) and a mixed fruit cocktail juice, on varroa mite infestation levels and overall honey bee colony health were investigated. The research aimed to address the decline in honey bee populations due to various factors including parasites, bacteria, viruses, and the use of pesticides. The study was conducted in a 20-hive experimental apiary, where colonies were divided into treatment and control groups. While the varroa mite infestation affected all colonies, no significant differences in mite infestation levels, population density, and honey yield were observed between the treatment and control groups. The study also detected viral (DWV, CBPV, and BQCV), fungal (Nosema ceranae), and bacterial (Melissococcus plutonius) pathogens in both symptomatic and asymptomatic colonies.

 


The study highlighted the importance of exploring natural alternatives for mite control and bee health. Although the natural treatments did not show significant differences in mite infestation levels, population density, and honey yield, the study provides valuable insights into the potential impact of these treatments on honey bee health. Additionally, the detection of various pathogens in both symptomatic and asymptomatic colonies underscores the complex challenges faced by honey bee populations. This research contributes to the ongoing efforts to understand and address the threats to honey bee populations, emphasizing the importance of continued investigation into natural treatments and their potential impact on bee health.

Science updates: Biological control method to improve honey bee resistance to viral infections

  Science updates: Biological control method to improve honey bee resistance to viral infections   The study investigates the impact of crude extracts from Talaromyces strains on honey bee resistance to Chronic Bee Paralysis Virus (CBPV), a significant factor in the decline of honey bee populations globally. The authors highlight the importance of pollinators in ecosystems and the threats posed by viruses and parasites, particularly the Varroa destructor mite, which exacerbates viral infections in honey bees. Seven Talaromyces strains were isolated from bee bread and tested for their antiviral properties. The extracts were evaluated in both in vivo (honey bees) and in vitro (mammalian cells) settings. The study involved feeding honey bees with sugar solutions enriched with fungal extracts and subsequently injecting them with CBPV to assess survival rates.   The results indicated that extracts from strains B13, B18, and B30 improved the survival rates of CB...

Winter mortality & temperature variations and Varroa mites

Image
  Science updates: Winter mortality & temperature variations and Varroa mites   The study examines the causal relationship between honey bee (Apis mellifera) winter mortality and environmental factors such as temperature variations and Varroa mite density. The research, conducted in a Central European apiary from 1991 to 2023, reveals consistent mortality patterns across years, with four distinct clusters of year-specific mortality trajectories identified. However, no significant differences were found in seasonal temperatures or Varroa destructor density among these clusters .   The study employs generalized additive mixed models (GAMM) to analyze individual bee mortality rates and structural equation models (SEM) to explore the causal network linking environmental conditions to bee mortality and honey production.   The results indicate that increased winter mortality is associated with lower winter temperatures and higher autumn infestations of ...
