I don't know if I would say it's 100% on the trucks (the honeybees didn't ask to be driven everywhere, after all), but the honeybees do disrupt the native ecosystems when they get to their targets; call it a 90-10 or a 95-5 split of culpability perhaps. Smaller scale hive operations that produce honey in one location probably don't have the same outsized impact on so many locations as these truck operations do.
