Synopsis : Our recent study on landscape-scale coordinated Varroa control suggest there are benefits for colony health. I know it makes sense, but how many actually do it?
In the magnum opus last week I discussed how bees discriminate nestmates from non-nestmates at the hive entrance. Inevitably I had to discuss the processes of drifting and robbing as these activities, together with the peripatetic drones, largely account for the ‘foreign’ bees arriving at a hive entrance.
I described drifting as a short-range phenomenon, predominantly of bees with immature cuticular hydrocarbon profiles 1, on their first few orientation flights. In contrast, I described robbing as a potentially long-range event that could occur over at least one kilometre.
I should have re-read the literature and refreshed my memory of what others have already reported for these activities before writing the post 🙁 .
