Project

Assessing the spread of bee diseases during hive transhumance

SPOHD

Brief description

SPOHD investigates how hive transhumance influences the spread of bee diseases and colony health during seasonal honey production.

Project Context

Moving hives between regions for seasonal honey production can expose colonies to new pathogens and ecological conditions. The project examined how transhumance affects bee health, microbiota and pathogen exposure during orange blossom and fir honey production.

Approach

Bee and honey samples were collected around hive movements between Attica, Argolis and Boeotia. Gut microbiome profiling and shotgun metagenomics of honey were used to track microbes, pathogens, plant resources and other organisms associated with the hive environment.

Outcome

Honey metagenomics non-invasively tracks foraging resources, gut microbiota, and pathogens from a single sample. Experimental tracking of hives moved to agricultural environments demonstrated immediate benefits to brood development alongside long-term risks, including increased Varroa infection and gut microbiome disruption.
