  • Honey Bees Can Detect Viruses in Food

    Honey bees encounter viruses in their environments, especially when they forage on flowers and other food sources. Being able to detect viruses is important for reducing infection and the spread of disease. Many insects, including honey bees, can detect viruses indirectly with sick nestmates, but it has been unclear if honey bees can directly detect viruses in food sources.

    To help beekeepers protect their colonies by reducing viral spread, ARS researchers from the Honey Bee Breeding, Genetics, and Physiology Research Unit in Baton Rouge, LA, studied if honey bees could sense viruses such as deformed wing virus, black queen cell virus, and chronic bee paralysis virus in contaminated food sources.

    In an experimental study, the researchers found that when honey bees were presented with the choice between a spiked sugar solution with viruses and a plain sugar solution, the honey bees preferred the virus-spiked solution.

    “These findings demonstrate that honey bees can directly detect the presence of viruses in contaminated food sources, which has important implications for pathogen transmission within pollinator communities and disease management strategies aimed at improving honey bee health,” said Michael Simone-Finstrom, ARS Research Molecular Biologist.

    According to Simone-Finstrom and ARS Research Entomologist Elizabeth Walsh, both co-lead authors of the study, the results highlight the need to control viral infections and spread in bee colonies.

    One major concern is viral spread from Varroa mites, parasitic pests that feed on honey bees. Currently, controlling Varroa mite populations is one of the most effective ways to protect honey bee colonies. Beekeepers can consider changing how they feed honey bees to limit outside insects from getting access to their food, according to Simone-Finstrom and Walsh.

    “Open feeding scenarios where bees from different colonies and other insects, who may carry viruses, get food from the same source may not be in the honey bees’ best interest,” said Walsh. “Beekeepers can consider an alternative like an individual colony feeder where only honey bees from one colony have access to the food.”

    It is unknown what mechanisms cause bees to gravitate towards the contaminated food sources. More research is underway to better understand honey bees’ foraging behaviors and how the viral presence affects their behaviors.

    “The study’s findings will help us with providing data-driven decisions in honey bee management and ecological decisions,” said Walsh. – By Jessica Ryan, ARS Office of Communications

  • New Pesticides Could Better Control Mite Disease in Honey Bees

    The Varroa mite (Varroa destructor) is a parasite of the honey bee (Apis mellifera L.) and is considered one of the species’ most serious threats, inflicting more damage and higher economic costs than all other bee keeping diseases. Varroa mites harbor numerous viruses and feed on honey bee adults and pupae, causing weakened immune systems, decreased body weight, and a shortened lifespan. The external wounds caused by repeated feeding can become infected with bacteria, fungi, and viruses.

    ARS researchers at the Bee Research Lab tested numerous pesticides for the chemical control of Varroa mites, and screened 40 compounds of samples in the lab (and three in the field). They documented how the viruses, carried by the mites, move within honey bee colonies and play key roles in bee-to-bee transmission. Through this research, two promising miticides were identified to manage the Varroa mite. This ARS research could lead to new management techniques that can minimize bee losses, reduce bee keeper and crop pollination costs, and ensure food security for all Americans. —By USDA Ag Research Service

  • Inaugural $100,000 Grant Program to Advance Honey Bee Health and Beekeeping Innovation

    Sweet Harvest Foods, the largest producer of raw, unfiltered honey and parent company of Nate’s Honey and Nate’s Hives, today announced the launch of Nate’s Hives Research Grant Program, reinforcing its commitment to advance the long-term success and sustainability of honey bees and the honey industry through science, innovation and collaboration.

    The program will provide up to $100,000 in annual funding for research projects that strengthen honey bee health, improve sustainable beekeeping practices, and drive innovation in pollination practices and across the honey supply chain. Proposals may be submitted by academic institutions, nonprofit organizations and industry researchers, with funding available for projects up to three years in duration.

    “As the industry leader in honey and a top apiary, we believe scale brings both responsibility and opportunity, and the honey industry’s future depends on science and collaboration,” said Michael Carle, Chief Executive Officer of Sweet Harvest Foods. “Through the Nate’s Hives Research Grant Program, we’re investing in the kind of research that will strengthen honey bee health, advance sustainable beekeeping practices and support pollination, a more resilient food ecosystem and the honey industry. Innovation has always been central to how we operate and it’s more important now than ever to fuel continued progress.”

    Proposals may address one or more of the following areas of focus: honey bee health, sustainable beekeeping practices, environmental impacts, supply chain innovation, consumer demand and nutritional impacts, or trade policy and production economics. Each submission will be evaluated by a volunteer review board composed of Sweet Harvest Foods employees and external experts from academia and the beekeeping industry.

    “At Nate’s Hives, we believe science can and should shape the future of beekeeping,” said Matt Halbgewachs, president of Nate’s Hives. “This grant program puts that belief into action and empowers researchers to uncover solutions that help honey bees and beekeepers everywhere. By linking researched insights with on-the-ground experience, we accelerate progress for honey bees, beekeepers, farmers and consumers alike.”

    Applications are due March 1, 2026, with awards announced on April 15, 2026. For full eligibility details, proposal requirements and submission instructions, visit nateshives.com/research-grant-program.
