bee-parasites
Bee parasites are organisms such as mites, fungi, and pathogens that infect and weaken bee populations, disrupting their health and reproductive success. Because bees are among the most important pollinators for flowering plants, parasite-driven declines in bee populations directly threaten plant reproduction, seed set, and the genetic diversity of plant communities. Understanding bee-parasite dynamics is therefore central to plant science, informing conservation strategies for wild flora and agricultural crop systems alike.

Scientists identified the bacteria living on Varroa destructor mites — the leading killer of honey bee colonies globally — finding that the mite carries its own distinct microbial community dominated by three bacterial families that may amplify the mite's harm to bees. This opens new avenues for targeted, microbiome-based treatments to protect bee colonies.
The Varroa mite microbiome is dominated by three bacterial families — Acetobacteraceae, Morganellaceae, and Segniliparaceae — identified through next-generation sequencing of the 16S rRNA gene.
The microbial community on Varroa mites is distinct from the honey bee's own microbiome, indicating the parasite harbors a unique bacterial ecosystem separate from its host.
The identified bacteria are hypothesized to contribute directly or indirectly to Varroa's pathogenicity, representing novel therapeutic and preventive targets for bee colony protection.
