Science updates:

Varroa control (Amitraz-Based Product)

 

The research article investigates the influence of two amitraz-based products, Apivar and Supatraz, on the control of Varroa destructor mite populations in honeybee colonies. The study is conducted in France, using field data and a dynamic model to compare the efficacy of the two products. Results show that while the percentage of efficacy of the two products in the field was not significantly different, Supatraz was found to kill mites faster and decrease 90% of the mite infestation in a shorter period compared to Apivar.

 


The study also reveals that the daily impact of the two different products on mite population varies, with Supatraz showing a higher daily mortality rate during the first two weeks, requiring a lower efficacy to stabilize the mite population due to its faster release of active ingredients. The comparison of the efficacy of the two products with different characteristics, such as duration of treatment and daily mortality rate, should be analyzed with caution.

 


Furthermore, the study provides insights into the development of resistance to acaricides in Varroa mites, highlighting the importance of control strategies to limit resistance and maintain high treatment efficacy. The research also emphasizes the influence of the proportion of resistant mites on treatment efficacy, demonstrating that the impact of resistance differs depending on the treatment and the proportion of resistant mites in the population. The findings suggest that the choice of products and active ingredients, along with the characteristics of the treatments, can significantly influence the efficacy and development of resistance in Varroa mites. The study concludes that the comparison of the efficacy of different products with varying characteristics should be carefully evaluated to better understand their impact on mite population control.

 


In summary, the research provides valuable insights into the influence of amitraz-based product characteristics on Varroa mite population control, emphasizing the need for caution when analyzing the efficacy of different treatments. The study offers important implications for beekeeping practices and the management of Varroa mite infestations, highlighting the significance of understanding the dynamics of resistance and treatment efficacy for effective mite population control in honeybee colonies.

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 ...
