For the last two years here in Phrae we've not had a piece of fruit from our 100+ Long An trees or our fruit trees! We normally have at least one wild bee hive per year, this year not even a bee let alone a hive?

All of our neighbours have had the same problem, although up in Rong Kwang (30Km away) they seem to have a lot of fruit?

Could this be the start of Thailands "Silent Spring"?

On holiday perhaps.

Perhaps you should think about setting up a couple of hives. I believe it's not so difficult to keep bees (I've never done so myself, but I've known a couple of people who have), and you would have the bonus of collecting the honey, too.
