First hit on https://www.google.ca/search?q=invasive+species+honey+bee is http://theconversation.com/bee-battles-why-our-native-pollinators-are-losing-the-war-40620 which claims:

We depend on native bees, like our humble bumble bees (Bombus spp.), to pollinate native flowers and crops. Bumble bees pollinate tomatoes, peppers, blueberries and many more of our favorite food items. Honey bees, which are widely used in agriculture and are suffering from colony collapse disorder, are a non-native species, and can’t replace the pollination services provided by native bees such as bumble bees.

...

Native pollinators, such as bumble bees, cannot easily be replaced by other species. This is because our native bees perform a special form of pollination, buzz pollination, where they use a unique vibration pattern to shake loose pollen from flowers. Many of our native crops, such as tomatoes and blueberries, need buzz pollination for efficient pollen transfer. So for the health and well-being of our native plants, we must care for our native bees.
