The Pollinator Partnership is expanding its bee certification program by adding a third-party verification option designed to encourage farmers and growers to create safe habitats for bees and other essential pollinators, which will improve sustainable and regenerative agriculture.
The program is being offered in collaboration with Where Food Comes From. Silk Canada, a product from Danone, and KIND Snacks have taken a step toward sustainable almond production by beta-testing a portion of their almond volume under the Bee Friendly Farming Certified third-party verified program. Two almond suppliers in California – Harris Woolf Almonds and Treehouse Almonds – are also participating in the beta test of the program.
European honey bees are arguably the world’s most famous insect. They’re honey bees! Fuzzy, buzzing, honey-making honey bees! And they deserve at least some of this attention. About one-third of the food we eat comes from plants that honey bees pollinate, and they face several threats, which has fueled a national campaign to “save the bees.”
But all of that attention on honey bees has, some ecologists argue, overshadowed their native counterparts: the wild bees. They’re an incredible bunch, found in all sorts of colors and sizes, and they’re important pollinators, too — better, by some measures, than honey bees. On the whole, native bees are also at a much greater risk of extinction, in part, because of the proliferation of European honey bees.
There’s been a well-documented shift toward earlier springtime flowering in many plants as the world warms. The trend alarms biologists because it has the potential to disrupt carefully choreographed interactions between plants and the creatures — butterflies, bees, birds, bats and others — that pollinate them.
Roughly half of North America’s 154 bat species are under threat from population decline in the next 15 years, according to a new report.
The inaugural “State of the Bats” report from the North American Bat Conservation Alliance indicates 52 percent of species could be at risk and that climate change will affect up to 82 percent of those species in the next 15 years.
Other hazards include wind turbine mortality and white-nose syndrome, a fungal disease that has already killed millions of bats on the continent.
A federal agency has officially given the Chicago Rockford International Airport the greenlight to restart construction on a $50 million expansion that is expected to bring new business and jobs to the city. Construction could resume as soon as Thursday.
But a conservation group is moving quickly to block the bulldozers. Activists want to put off a project they say threatens prized prairie habitat and is a home of the Rusty Patched Bumble Bee.
The fight over an 8,000-year-old remnant prairie in the middle of one of the country’s largest cargo airports has unfolded over the past two years and put the spotlight on Illinois’ dwindling prairie ecosystems.
To receive a conditional license, which usually lasts for one year and is subject to further evaluation by the USDA, veterinary biological products must be shown to be pure, safe and reasonably likely to be effective. Dr. Jennie Durant, an agriculture researcher at the University of California, Davis, who specializes in honeybee health, explains why this vaccine is potentially an important step in ongoing efforts to protect pollinators.
An outbreak of American foulbrood is effectively a death sentence for a bee colony and can economically devastate a beekeeping operation. The spores from the bacteria, Paenibacillus larvae, are highly transmissible and can remain virulent for decades after infection.
Once an outbreak occurs, beekeepers typically have to destroy any bee colonies that they know were infected to avoid spreading the disease. They also have to destroy the hive boxes the colonies were stored in and any equipment that may have touched infected colonies.
Beekeepers have used antibiotics preventively for decades to keep foulbrood in check and treat infected colonies. Often they mix the antibiotics with powdered sugar and sprinkle it inside the colony box. As often happens when antibiotics are overused, scientists and beekeepers are seeing antibiotic resistance and negative impacts on hive health, such as disruption of the helpful microbes that live in bees’ guts.
2. How effectively does the vaccine prevent infection?
Studies are still analyzing its effectiveness. One published study demonstrated a 30% to 50% increase in resistance to American foulbrood in a vaccinated queen’s offspring.
While this might seem low, it’s important to put the results in context. Given how deadly and contagious American foulbrood is, researchers did not want to directly expose an outdoor hive to foulbrood with an unproven vaccine. Instead, they conducted lab studies where they exposed test hives to around 1,000 times the number of American foulbrood spores a colony would typically be exposed to in the field. Dalan, the manufacturer, has field trials planned for 2023.
3. How do you vaccinate honeybees?
It’s not done with tiny needles – beekeepers mix the vaccine into bee food. This approach exposes queen bees to inactive Paenibacillus larvae bacteria, which helps larvae hatched in the hive to resist infection.
This is not a mRNA vaccine, like the Pfizer and Moderna COVID vaccines. It’s a more traditional inactive vaccine like the one we use against polio. To understand how the vaccine works, it’s helpful to know what queen bees eat: a protein-rich substance called “royal jelly” that is secreted from glands on the heads of young worker bees.
When queen bees are shipped to a beekeeper, they are typically placed in a small cage with 50 to 200 worker bees that have been fed something called queen candy. This substance is often made with powdered sugar and corn syrup and has the consistency of sugar cookie dough or modeling clay. Worker bees consume the candy, produce royal jelly and feed it to the queen.
The vaccine’s delivery method uses this unique system. A beekeeper can mix the vaccine with the queen candy, which is then digested by worker bees. They produce royal jelly and feed it to the queen, who digests it and then transfers the vaccine to her ovaries. Once she is transferred to the hive and begins laying eggs, the larvae that hatch from those eggs have a heightened immunity to American foulbrood.
4. Who will use the vaccine?
According to representatives at Dalan, limited quantities of the vaccine should be available starting in spring 2023 to commercial beekeepers and bee producers, with the aim of supplying smaller-scale beekeepers and hobbyists in the future.
5. How long will a dose last?
Dalan is still researching the specifics. Its current understanding is that it will last as long as the queen bee can lay eggs. If she dies, is killed or is replaced, the beekeeper will have to purchase a new vaccinated queen.
Dalan is also working on a vaccine to protect bees against European foulbrood. This disease is less fatal than American foulbrood, but is still highly infectious. Beekeepers have been able to treat it with antibiotics but, as with American foulbrood, they are seeing signs of resistance.
