The Best Way To Kill Varroa With Oxalic Acid: SUBLIMATION

To determine Varroa mortality we took two samples of worker bees (mean = 267 bees per sample) from each colony. The first was taken just before oxalic acid treatment and the second 10 days later, when the mortality caused by the oxalic acid was over but before any capped brood was present. The sampl...

Description
Summary:To determine Varroa mortality we took two samples of worker bees (mean = 267 bees per sample) from each colony. The first was taken just before oxalic acid treatment and the second 10 days later, when the mortality caused by the oxalic acid was over but before any capped brood was present. The samples were frozen and analysed later. The dead bees were placed into a double-mesh honey strainer. A jet of warm water from a hose nozzle was used to wash the Varroa off the bees.
