Viruses Identified as Key Factor in 2025 Colony Losses

A recent study from the USDA brings more understanding to the 2025 colony losses.

Varroa mites are spreading viruses such as Deformed Wing Virus (DWV) and Acute Bee Paralysis Virus (ABPV) within the colonies. The study revealed that Varroa mites from collapsed colonies show resistance to amitraz, a key miticide.

The discovery calls for new control strategies for this parasite.

While viruses were the primary factor for loss, the study also pointed to other manageable stressors like nutrition and agrochemical exposure.

This research reinforces the importance of prioritizing healthy colonies to support pollination and agriculture.

Our team found the research fascinating.
