The primary purpose of this visit, now that the main honey crop has been harvested, was to perform a disease inspection – This was of both adult bees and brood. Once the queen had been located the frames of brood were shaken in or order to obtain a clearer view and facilitate early detection of brood diseases.
Of the nine colonies examined only two showed deformed wings secondary to severe varroosis. No other diseases were evident.
(See Rowan’s video synopsis below).
N.B. I believe Peter’s colony also had a problem with varroa.
Plan: Order MAQS for appropriate treatment.
