Southern California Honeybees Demonstrate Resistance to Varroa Mites
Researchers at the University of California–Riverside have discovered a unique hybrid honeybee population in Southern California that shows natural resistance to Varroa mites, a deadly parasite affecting honeybee colonies across the U.S. The study, published in Scientific Reports, highlights that these bees, which are a genetically diverse mix from various honeybee lineages, have 68% fewer mites compared to commercial honeybee colonies. This resistance is observed even at the larval stage, suggesting a genetic basis for the trait. The findings offer hope for reducing reliance on chemical treatments, which have been losing effectiveness over time.
