I wouldn't be so sure. that there aren't records of that happening only means that there aren't records of that happening. could be because all the bees were getting along just fine, but it could also be because nobody bothered (or had the resources) to look into it.
bumblebees, alkali bees, and other less well-known pollinating insects are also relatively new to the commercial/industrial pollination game, so their impacts on ecosystems are less likely to have reached anything resembling a steady state or dynamic equilibrium. that makes those impacts a lot easier to understand because they can be observed in real time. the consequences of honeybees spreading through the Americas, in contrast, are largely a case of forensics by this point, though modern beekeeping methods are no doubt causing a whole new wave of ecosystem changes.
