No, you've got it garbled.

It was USA NATIVE bumblebees, exported and reproduced ("bred") 
overseas, and then shipped back to the USA that carried the 
European nosema in, escaped from their greenhouses (which 
happens a lot), and thereby wiped out two native species
of bumblebees.

So, the exploitation of native bumblebees in agriculture
caused the extinction of two types of native bumblebees.

Yet self-described "conservationists" and "preservationists" 
persist in advocating the use of native species in production 
agriculture, ignoring the track record in terms of its 
direct negative impact on the exact species they profess to 
wish to preserve.

To repeat the lesson taught by the extinctions, 
exploitation is neither preservation no conservation.
