We need pollinators
The other side of helping bees with treatments of pesticides and antibiotics is that you keep propagating the bees that can't survive. This is the opposite of what we need. We beekeepers need to propagating the ones that CAN survive. Also we keep propagating the pests that are strong enough to survive our treatments. So we keep breeding wimpy bees and super pests. Also for years we have bred bees to not rear drones, be larger, and use less propolis. Some of these make them reproductively challenged (less drones and larger) and some make them less able to handle viruses (less propolis).
