Re: Question, Will AHB from Puerto Rico survive in cold areas of the United States?
Before you invest a lot of resources in the idea of exporting bees from Puerto Rico to the mainland US, it seems to me that it would be prudent to confirm that such shipments of bees would be legally permissible. I suspect that you will find it is not permissable.
For a start, see: https://www.aphis.usda.gov/aphis/our...m_Soil_Permits
While that summary page does not specifically mention Puerto Rico, it implies [to me, at least] that bees from Puerto Rico will be considered 'foreign' bees as they are not 'continental USA' bees. Discussing your plans with APHIS would be a good start on getting more info.
