Scientists identify culprit behind biggest-ever U.S. honey bee die-off

U.S. beekeepers experienced a record 62% die-off of commercial honey bee colonies between June 2024 and January 2025. A new USDA study identifies the culprit as bee viruses spread by parasitic mites that have become resistant to amitraz, the primary miticide. This resistance poses a significant threat to U.S. agriculture, which relies heavily on honey bee pollination.

Note

ok, so mites are the "culprit".

yet, the problem seems more complex to that as climate change, pollution, land loss and city growth all have had a hand in this outcome.

with that said, focusing some effort on the reactive efforts seem useful if they can achieve results in the short term.
