Effects of temperature on thymol based Varroa treatments - PH0539

The primary aim of this project is to determine the effects of ambient temperature on Thymol-based Varroa treatment products for beekeepers. Thymol treatments are temperature dependent and beekeepers in England and Wales have reported thymol-based products are ineffective in cooler locations. The second of this project is therefore to provide advice to beekeepers on the efficacy of thymol based approved veterinary medicines for the treatment of Varroa across locations with different temperatures in England and Wales.

1. To design an experimental strategy to test the efficacy of thymol-based products for treating honey bees infested with Varroa at different geographical locations.
2. To provide well detailed protocols covering the conditions under which the treatments should be done, how the treatments should be delivered and the data to be gathered.
3. To oversee and direct the treatments to be done and data gathering.
4. To analyse the data gathered and prepare a report with recommendations for how best to use thymol-based products in England and Wales.
