Control of Varroa Mites in Saskatchewan Honeybee Populations

Varroa mites are one of the main causes in the decline of honey bee health across Canada. To keep mites under control, beekeepers rely on the use of miticides. Unfortunately this practice has led to miticide resistant mites which has resulted in the failure of mite control and high bee mortality (average 37.8% per year). A substantial change in mite control strategies must be developed in order to reduce bee mortality. The most sustainable approach is an Integrated Pest Management (IPM) strategy that is based on an effective and environmentally sensitive approach. This tactic relies on a combination of options including the use of genetic resistant bees. Varroa resistant bee stocks that provide a significant level of protection are becoming available. These resistant bees can play a key role in Varroa mite IPM while keeping bees healthy. The objective of the proposed project is to evaluate the differences and similarities between two-mite resistant bee stocks including Pol-Line descendant (Paradise) resistant stock developed by the USDA and “Saskatraz” bee stock to Saskatchewan local stock. Our assessments will determine suitability of these mite resistant stocks to be integrated into our local bees to enhance the IPM of varroa and maintain healthier bees.
