Towards a Stable Host–Parasite Relationship Between Honey Bees and Varroa Mites Through Innovative Beekeeping

open access: yesEnvironmental Microbiology, Volume 27, Issue 5, May 2025.
An innovative Varroa treatment increases Varroa pressure and Deformed Wing Virus (DWV‐B) load in summer. The increased mite and virus levels are reduced with effective summer treatment so that finally there is no difference between both groups in terms of DWV‐B and mite load shortly before overwintering.

In situ infestation of sea trout Salmo trutta with salmon louse Lepeophtheirus salmonis reveals parasite‐induced behavioral modifications

open access: yesJournal of Fish Biology, Volume 106, Issue 4, Page 1083-1094, April 2025.
Abstract In areas with high densities of salmon farming, spillover of the ectoparasitic salmon louse Lepeophtheirus salmonis poses a major threat to wild anadromous salmonids. By combining experimentally salmon louse infestation (mean ± standard deviation = 0.25 ± 0.25 lice g−1 fish) with acoustic telemetry, we studied the behavior of wild first‐time ...
