Biopreparations for bee health

Biopreparations for bee health are live-microbe, vaccine and botanical preparations that protect managed honeybees and bumblebees from American foulbrood, Nosema, viruses and the Varroa mite — the drivers of the record colony losses that threaten a U.S. crop-pollination market worth more than $15B a year. Dalan Animal Health’s American-foulbrood vaccine, the first honeybee vaccine to receive USDA conditional licensure (December 2022), primes the queen against Paenibacillus larvae and passes protection to her offspring through trans-generational immunity. On the probiotic side, Lactobacillus melliventris raised Bombus terrestris colony survival 2.5-fold with more than 10% more flowers visited, while Vita’s HiveAlive seaweed-and-thymol supplement delivered up to an 89% colony-population gain, 40% more honey and 57% fewer Nosema spores in independent trials. The category spans vaccines, probiotics, pathogen biocontrol and nutrition supplements.

The key directions of bee-health biopreparations are:

1. Honeybee vaccines (Honeybee Vaccines): prime the queen via trans-generational immune priming so her offspring resist Paenibacillus larvae (American foulbrood) — Dalan’s USDA-conditionally-licensed vaccine.
2. Probiotic and microbiome preparations (Bee Probiotic & Microbiome Preparations): native gut bacteria such as Lactobacillus melliventris and engineered yeast that colonize the bee gut and lift colony survival and pollination performance.
3. Pathogen biocontrol (Bee Pathogen Biocontrol): biological agents targeting Varroa, foulbrood and bee viruses (dsRNA/RNAi antivirals, entomopathogenic fungi).
4. Nutrition and immunity supplements (Bee Nutrition & Immunity Supplements): seaweed, thymol and propolis-based feed additives (Vita HiveAlive, Beeflow Max Poll) that boost gut health and cold tolerance.

Cross-cutting technologies of the sector:

• Trans-generational immune priming (Trans-Generational Immune Priming): vaccinating the queen so egg jelly conveys pathogen resistance to offspring — the mechanism behind Dalan’s foulbrood vaccine.
• Bee gut microbiome engineering (Bee Gut Microbiome Engineering): native and engineered bacteria/yeast (Lactobacillus, engineered Saccharomyces) that colonize the gut and deliver protection.
• dsRNA/RNAi antivirals (dsRNA/RNAi Antivirals): double-stranded RNA targeting bee viruses (Deformed Wing Virus) and Varroa, an emerging biocontrol class.

The stack pairs immune-priming vaccines with gut-microbiome engineering and botanical/nutritional supplements.

1. Trans-generational immune-priming vaccines (Honeybee Immune-Priming Vaccines):
   • Dalan primes the queen against Paenibacillus larvae so worker jelly conveys resistance to eggs, the basis of the first USDA-conditionally-licensed honeybee vaccine.
   • The platform extends toward Deformed Wing Virus, with trial correlations showing reduced DWV in vaccinated colonies.
2. Probiotic and microbiome therapeutics (Bee Gut Microbiome Therapeutics):
   • Biobest’s Lactobacillus melliventris colonizes Bombus terrestris, persisting long-term and lifting survival 2.5-fold with more than 10% more flowers visited.
   • Engineered yeast (Saccharomyces) delivering dsRNA extends the microbiome route toward antiviral protection against bee viruses.
3. Botanical and nutritional supplements (Botanical & Nutritional Supplements):
   • Vita’s HiveAlive blends Irish seaweed extracts with thymol, lemongrass oil and lecithin to cut Nosema spores 57% and raise colony population up to 89% in independent trials.
   • Beeflow’s Max Poll feeds bees to lift immunity and cold tolerance, extending the pollination window below 50°F for an 18% gain in blueberry flower visits.
