A recent paper on this topic (same general message as on the linked website):
> We found compelling evidence that honey bee introductions indirectly decrease pollination by reducing nectar and pollen availability and competitively excluding visits from more effective native bees. In contrast, the direct impact of honey bee visits on pollination was negligible, and, if anything, negative. Honey bees were ineffective pollinators, and increasing visit quantity could not compensate for inferior visit quality.
> Feral bee colonies usually just die after 18-24 months. That's long enough to swarm repeatedly, so mite pressure isn't really a threat to honeybees as a species in the wild. They live long enough to reproduce and almost nobody tries to harvest honey from them for sale. There's basically no chance that mites will make feral honeybees go extinct.
Rather, mite parasitism's an economic problem that threatens commercial beekeeping [...]. Keeping bees alive with both mites and pesticides, especially in the face of climate change, is really hard if you need to make money doing it.
