I'm in Australia, and we only got Varroa in 2022, and it was suppressed for about a year before a regrettable 'oh well' attitude overwhelmed us. The last couple of years has seen a breathtaking impact.
Anecdata - one of my five hives is still struggling on.
Australia's experience since 2022 had (I thought) laid to rest a lot of the 'It's not varroa that's the problem' claims from armchair analysts.
But yes, per my earlier point, lots of our tree crops require honeybees to be shipped in - just because of broadacre / monoculture style farming. Well, along with honey production being its own industry - so they need to follow the nectar, and change up the flavours a bit, but also some trees just don't produce useful amounts of nectar but absolutely require a lot of pollinators for a few weeks only (almonds / peaches I think fit this category).
