April 7, 2025 - We just wrapped the most deadly winter on record for commercial honey bees in the U.S. They not only make honey, they also pollinate more than a hundred U.S. crops here for a total of $18 billion in agricultural revenue. KVPR's Kerry Klein reports from central California, where the bee industry is scrambling to recover from these sudden, massive losses.

July 8, 2025 - Norman Carreck, a senior technician at the University of Sussex, who was not involved in the research, says: “Sadly, it was inevitable that major honeybee colony losses would again occur in the US at some point.

September 15, 2025 - That was the highest loss ever recorded in the industry, said Dr. Britteny Kyle, who gave two honey bee sessions at the AVMA Convention 2025 in July in Washington, D.C.

March 20, 2025 - In January 2025, commercial beekeepers discovered sudden mass honey bee colony losses (60-100%).

March 20, 2025 - Cornell bee experts are analyzing samples of bees and related material to help identify the cause of unprecedented managed honeybee losses this winter.

May 14, 2025 - The sudden and unexplained deaths of honey bees in the past year have sparked a national investigation to determine what killed untold numbers of these pollinators.

March 25, 2025 - The latest, record leap in honeybee losses is now being investigated by staff at the US Department of Agriculture, which is analyzing bees, wax and pollen to determine if parasites and viruses are to blame for the deaths.

May 8, 2025 - “In January 2025, beekeepers across the country began reporting unexpected large-scale honey bee losses—we now know the largest ever recorded in the U.S.,” said Danielle Downey, executive director of Project Apis m. “In response, USDA ...

Whatever the culprit or culprits, beekeepers have been severely affected by these loss events. It is of the utmost importance for the commercial beekeepers participating in this study to pinpoint the underlying issue before the arrival of winter in 2024. Many beekeepers said they could not recoup from a similar event if it were to happen in 2025.

January 7, 2026 - Most notably, the research team reported that all Varroa mites they examined from collapsed and surviving colonies showed genetic markers for resistance to the acaricide (mite-specific pesticide) amitraz, the current primary control method for Varroa mite. They also found high prevalence of Varroa mite-vectored viruses, which are known to cause mortality in honey bees. These results suggest that the difficulty of controlling Varroa mite is likely the driver of the massive colony losses observed this year.
