Resisting varroa

Fascinating presentation yesterday evening from Steve Riley, author of The Honey Bee Solution to Varroa.

In a nutshell, the thesis is that treating bees with miticides is creating selection pressure for treatment-resistant mites while simultaneously creating selection pressure for varroa-susceptible bees.

As Steve confirms, this is hardly news.

The point he and others make is that it is possible to select for mite-resistant bees by close observation of behaviour, and - over time - stop treating with miticides.

The book "explains the practical steps beekeepers can take to identify and select for easily observable Varroa-resistant traits in their colonies. The science behind the bees’ mechanisms for controlling their mite populations is explained, in what is a bee-led solution to the biggest challenge facing the European honey bee."
