Abstract excerpt
Deformed wing virus (DWV) is a major viral pathogen of Apis mellifera, existing mainly as two genotypes, DWV-A and DWV-B, which differ in transmission dynamics and virulence. This study presents a three-year national molecular surveillance (2021-2023) of Italian honey bee colonies to investigate the spatio-temporal distribution of both variants in relation to apiary density, geographical gradients, and land-use...
