You probably won't have any problem with your native honey bees. They have had plenty of time to become resistant to the local conditions.

North America and Europe have seen a huge increase in the bee population over the last 100 years due to bee farming. The bee populations were produced with bees that were bred for honey making and fast growth, not disease resistance. That is why we are having a problem now.

The habitat loss is a perpetual problem that we will probably always need to work on.
