Beekeepers in the United States have experienced high losses of managed honey bee (Apis mellifera) colonies for more than a decade. Long-term, multi-year monitoring efforts are crucial to provide temporal and spatial context these losses. To document explain losses, Bee Informed Partnership has conducted national surveys on since spring 2011, continuing work first commissioned by Apiary Inspectors America 2007. Here we present survey results from three years – 2017–18, 2018–19, 2019–20. Each year, colony loss rates were estimated compared among periods summer, winter, annual beekeeping operation types based their number backyard (≤50 colonies), sideline (51-500 commercial (>500 colonies). At level, recorded highest winter (37.7%) 2018–2019, while 2019 marked year with summer (32.1%). As documented past surveys, observed that smaller scale beekeepers when larger types. Similarly, higher during other Overall, our highlight variability, specifically years, States, suggest strong effect size.

Honey Production and Climate Change: Beekeepers’ Perceptions, Farm Adaptation Strategies, and Information Needs

Insects, Journal Year: 2023, Volume and Issue: 14(6), P. 493 - 493

Published: May 25, 2023

Because climate change has severely impacted global bee populations by depleting their habitats and food sources, beekeepers must implement management practices to adapt changing climates. However, in El Salvador lack information about necessary adaptation strategies. This study explored Salvadoran beekeepers' experiences adapting change. The researchers used a phenomenological case approach conducted semi-structured interviews with nine who were members of Cooperative Association for Marketing, Production, Savings, Credit Beekeepers Chalatenango (ACCOPIDECHA). perceived water scarcity, as well extreme weather events (e.g., increasing temperature, rain, winds), the leading change-induced challenges production.

Nationwide genomic surveillance reveals the prevalence and evolution of honeybee viruses in China

The economic and environmental value of honeybees has been severely challenged in recent years by the collapse their colonies worldwide, often caused outbreaks infectious diseases. However, our understanding diversity, prevalence, transmission honeybee viruses is largely obscure due to a lack large-scale longitudinal genomic surveillance on global scale.We report meta-transcriptomic sequencing nearly 2000 samples two most important widely maintained species, as well an associated ectoparasite mite, collected across China during 2016-2019. We document natural diversity evolution China, providing evidence that multiple commonly co-circulate within individual bee colonies. also expanded data for 12 revealed novel genetic variants lineages with China. identified more than 23 from mite viromes, some exhibiting ongoing replication respective hosts.

High abundance of lactobacilli in the gut microbiome of honey bees during winter

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: March 3, 2025

Honey bee gut microbiota play specific roles in promoting host growth and physiology by regulating the immune system, behavior, metabolism, neurological processes. While of honey queens, workers, larvae has been extensively studied, less is known about composition winter worker bees. This study investigates dynamics overwintering adult bees, focusing on two commercial strains: Bolton™ bees Mann Lake™ These Apis mellifera strains were investigated under different storage conditions (indoor at 6 °C outdoor natural conditions) during months (October, November, December). Utilizing 16S rRNA gene amplicon sequencing, we characterized microbial whole gut. We observed Lactobacilli dominated all guts with a significantly higher abundance unclassified Lactobacillus species while apis showed October. Bolton exhibited levels Bartonella (denoted as uncultured) Bifidobacterium, along an unexpected presence Wolbachia. In contrast, Lake demonstrated increased Commensalibacter. Our results suggest that Shannon diversity influenced month rather than strain or conditions. also found significant differences Bray Curtis index month. Overall, taxonomical was not affected whether hives stored outside constant temperature indoor storage. However, various bacterial across months, slight variations between strains. Given potential benefits microbiome for health nutrition, our data suggests genus may role

Apis mellifera as a Model Species to Evaluate Toxicological Effects of Fungicides Used in Vineyard Agroecosystems

Journal of Xenobiotics, Journal Year: 2025, Volume and Issue: 15(1), P. 18 - 18

Published: Jan. 21, 2025

Agroecosystems provide habitats, food, and water for many pollinators insects, but they are also heavily exposed to threats from the widespread use of pesticides fertilizers. Managed honeybees wild bees encounter in vineyards by collecting morning dew vine leaves accessing sugars grapes, particularly during dry periods. This study assessed toxicological effects commercial fungicide formulations Fantic FNCWG® Ramedit combi®, both individually combination, on honeybees. Using a multi-biomarker approach, we evaluated neurotoxicity, metabolic disturbances, phase II detoxification processes, immune system function. Our findings revealed that mixtures with multiple active ingredients affect differently than single compounds. Biomarker responses highlighted how these complex disrupt various enzymatic pathways; including function; altering critical enzyme kinetics involved potentially impairing essential bee functions. emphasizes need more comprehensive research into sublethal pesticides, those used vineyards, which understudied compared orchards.

Over the past two decades, there has been an alarming decline in number of honey bee colonies. This phenomenon is called Colony Collapse Disorder (CCD). Bee products play a significant role human life and have huge impact on agriculture, therefore bees are economically important species. Honey found its healing application various sectors life, as well other such royal jelly, propolis, pollen. There many putative factors CCD, air pollution, GMO, viruses, or predators (such wasps hornets). It is, however, believed that pesticides microorganisms mass extinction Insecticides chemicals dangerous to both humans environment. They can cause enormous damage bees’ nervous system permanently weaken their immune system, making them vulnerable factors. Some insecticides negatively affect are, for example, neonicotinoids, coumaphos, chlorpyrifos. Microorganisms diseases bees, weakening health colony often resulting extinction. Infection with may result need dispose entire hive prevent spread pathogens hives. Many aspects still unclear. The deepen knowledge this matter crucial, bearing mind how these animals life.

We conducted a retrospective study to examine the long-term trends for global honey bee population and its two main products: beeswax. Our analysis was based on data collected by Food Agriculture Organization of United Nations from 1961 2017. During this period, there were increases in number managed colonies (85.0%), production (181.0%) beeswax (116.0%). The amount produced per colony increased 45.0%, signifying improvements efficiency producing honey. Concurrently, human grew 144.0%. Whilst absolute globally, capita declined 19.9% 13.6 1000 10.9 Beeswax had similar trend as reduced 8.5% 8.2 7.5 kg population. In contrast, 42.9% at level. growth outpaced that colonies.
