Скачать или смотреть Speedy Oxalic Acid Sublimation in a Snow Drift

This video is a single clip of 4 honey bee colonies (1 pallet) being fumigated with oxalic acid. This video is sped up (4x), but in real-time it took 4:28 minutes (or 1 minute and 7 seconds per colony) which is a bit slower than when not working in a snow drift, especially if you add in the time it took to dig the colonies out of the snow.

There was a lot of snow that recently fell, and the row of hives next to our wind fence needed to be dug out to access the entrances. We are sublimating the colonies with Oxalic Acid to help control Varroa mites, and doing it in the winter when there is no (or very little) brood makes this method of applying OA more effective than it would be at times when there is capped brood in the colonies. This is because OA does not penetrate the wax cappings covering the honey bee brood where the mites are reproducing and feeding on young bees. We are using an InstantVap 18V Oxalic Acid Vaporizer to sublimate ~2.5 grams of OA in a double brood chamber colony.

Thanks for watching!

Our bee & pollination research lab at the University of Lethbridge is led by Dr. Shelley Hoover. Through our research we are continually working to learn all we can about bees, pollination, and beekeeping - and to share that information with anyone who is interested in learning along with us.

We love bees - honey bees, bumble bees, and all the bees! Please subscribe to our channel and join us on our journey to learn more about bees, beekeeping, and all the research we conduct!    / @uleth_bees
