Beekeepers devastated as mysterious losses reach 'catastrophic' highs: 'We should be worried'

An unprecedented loss of honeybees over the winter has put staple crops at risk in the coming season. The uncertain cause of this mass die-off has left beekeepers and farmers bewildered and facing a shortage of 300,000 to 500,000 hives, per the San Francisco Chronicle.

What's happening?

A survey of beekeepers across the United States by "Project Apis m." found that a "catastrophic" 1.1 million colonies were lost between last June and last month.

Zac Browning, a commercial beekeeper, described the scale of the losses as "completely unsustainable" and said if the losses continue, "we simply won't be able to sustain current food production." On average, commercial beekeepers lost 62% of their bees, far past the industry's "breaking point" of 50%, per the Chronicle.

Blake Shook, owner of Desert Creek Honey in Texas, told the Chronicle: "Once we get to 70% to 80%, you can't recoup your numbers anymore. It's a scary place, and we should be worried about national food security."

Why are declining bee populations concerning?

Honeybees play a critical role in food production as pollinators for 130 crops in the U.S. According to the U.S. Department of Agriculture, they pollinate $15 billion worth of crops each year.

According to the Chronicle, one of the most vulnerable crops to depleted stocks of bees is almonds — one of California's most profitable crops. The Golden State produces 82% of the world's almond supply, as reported by the Los Angeles Times.

Honeybees face several threats, which experts typically classify as the "four P's": pesticides, parasites, pathogens, and poor nutrition, per the Chronicle.

Commercial pesticides can be highly toxic to bees and are linked to a host of other health and ecological problems. Parasites like the small hive beetle can also inflict immense damage to a hive, while pathogens like the American foulbrood can wipe out entire colonies. Finally, poor hive nutrition makes all of the aforementioned afflictions all the worse.

What's being done about falling bee populations?

The dangers of pesticides to bees can be mitigated in multiple ways.

The University of Georgia's College of Agricultural and Environmental Sciences offers a few suggestions. One is timing; bees forage during the day, so applying pesticides in the evening will mitigate losses.

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression Dinotefuran is known to negatively affect honeybee ( Apis mellifera ) behavior, but the underlying mechanism remains unclear. The magnetoreceptor ( MagR , which responds to magnetic fields) and cryptochrome ( Cry2 , which is sensitive to light) genes are considered to play important roles in honey bees’ homing and localization behaviors. Our study found that dinotefuran, even without direct contact, can act like a magnet, significantly altering MagR expression in honeybees. This non-contact exposure reduced the bees’ homing rate. In further experiments, we exposed foragers to light and magnetic fields, the MagR gene responded to magnetic fields only in the presence of light, with Cry 2 playing a key switching role in the magnetic field receptor mechanism ( MagR–Cry2 ). Yeast two-hybrid and BiFc assays confirmed an interactio...

“Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns

“Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns The World Beekeeping Awards will not grant a prize for honey next year due to the “inability” to thoroughly test honey for adulteration. The announcement comes amid the rise of honey fraud in the EU, where a 2023 investigation found that 46% of 147 honey samples tested were likely contaminated with low-cost plant syrups. Apimondia, the International Federation of Beekeepers’ Associations, organizes the event at its Congress, whose 49th edition will be held in Copenhagen, Denmark, in September 2025. The conference brings together beekeepers, scientists and other stakeholders. “We will celebrate honey in many ways at the Congress, but honey will no longer be a category, and thus, there will be no honey judging in the World Beekeeping Awards. The lessons learned from Canada 2019 and Chile 2023 were that adequate testing was impossible if we are to award winning honey at the Con...

New Report – Interlocked: Midwives and the Climate Crisis

New Report – Interlocked: Midwives and the Climate Crisis Earlier this year, midwives from 41 countries shared their experiences of working in communities affected by climate change through our survey, Midwives’ Experiences and Perspectives on Climate Change. Their voices shaped our new report, Interlocked: Midwives and the Climate Crisis , which highlights how midwives are already responding to the health impacts of climate disasters like floods, wildfires, and extreme heat—and why they must be included in climate action plans. What did we learn?Climate change is damaging community health: 75% of midwives reported that climate change is harming the communities they serve, with rising rates of preterm births, food insecurity, and restricted access to care during disasters like floods. Midwives are critical first responders: Midwives are often the first and only healthcare providers on the ground in crises, delivering care during wildfires, floods, and extreme heat. Midwives face signi...

He was immediately admitted to a hospital for treatment but could not survive the ordeal. Fondly known as ‘Boggu’ in the Porkodi area, Pushparaja was well-known for his dedication to delivering newspapers on foot to every household. He was admired for his generosity, as he often distributed sweets to schoolchildren on Independence Day using his own earnings and contributed part of his income to the betterment of society. Pushparaja was unmarried and is survived by three brothers and one sister.

Start the New Year Humming Like a Bee

Start the New Year Humming Like a Bee There are lots of opportunities to be as busy as a bee during these winter holidays. As we hustle toward the dawn of the New Year, it can be hard to notice that the natural world is actually suggesting something different for us right now. We’re past the solstice, but the winter still stretches ahead, the days are still short and the nights long. We’re being invited into a quieter, more inner-focused time. The ancient yogis were all about this inner focus. In India, for example, the Upanishads, the Sanskrit writings that accompanied the development of Hinduism — and alongside it, yoga — beginning around 800 B.C.E., went deeper than earlier texts had into philosophy and questions of being. With the goals of increased inner awareness and higher consciousness, yoga was at that time not yet as focused on the body or on asanas, as it now can tend to be. But the yogis did develop many practices to try to open the way to those goals. They discovered...

The largest “killer hornets” in the world were exterminated in the US

The largest “killer hornets” in the world were exterminated in the US The US informed that it had exterminated the worldʼs largest hornets, nicknamed "killer hornets" — they are capable of occupying a hive of honey bees in just 90 minutes, decapitating all its inhabitants and feeding their offspring to their own. This was reported by the Department of Agriculture in Washington. The hornets, which can reach five centimeters in length, were previously called Asian giant hornets, but in 2019 they were also spotted in Washington state near the Canadian border. In China, these insects killed 42 people and seriously injured 1,675. A dead northern giant hornet (below) next to a native bald hornet. According to experts, the hornets could have entered North America in plant pots or shipping containers. The hornet can sting through most beekeeper suits because it produces nearly seven times more venom than a honeybee and stings multiple times. Thatʼs why the Washington Departme...

The Unexpected Surge: America's Honeybees Buzz Back to Record Numbers

The Unexpected Surge: America's Honeybees Buzz Back to Record Numbers In an age where environmental narratives often lean towards loss and decline, the story of the American honeybee offers a glimmer of hope and a puzzle to solve. Recent data from the Census of Agriculture reveals an astonishing rebound in the honeybee population, now soaring to an all-time high of 3.8 million colonies. This revelation comes as a surprise against the backdrop of two decades marked by fears of colony collapse and the potential ramifications for ecosystems and agriculture. The surge in bee populations brings to light a series of questions and insights into the intertwined worlds of agriculture, conservation, and legislation. Central to this narrative is the state of Texas, where legislative changes have catalyzed a beekeeping boom by offering agricultural tax breaks to landowners cultivating honeybees. This policy shift, coupled with the entrepreneurial spirit of Texans and the essential role of bees...
