Exactly.
A number of factors are known to contribute to the loss of bees in Canada. Varroa, a parasitic mite, is one of the factors contributing to the loss of a large number of bees. The parasite is becoming increasingly resistant to pesticides and it has no natural predators. Is research being done into that? For example, we know that, if we put natural predators into greenhouses where tomatoes and cucumbers are grown, we do not have to use pesticides. Do you know if research is being done to find a natural predator?
