Last year we had a lot of bees with deformed wings with many of them just walking away from the hive. This year we have been doing powdered sugar treatments every 7-10 days for the last month and our natural mite drop is around 10 mites/day. We see "some" bees with deformed wings, maybe one or two here and there.
My question is: If we see some deformed wings but seem to have reasonably low mite drops, is there a problem? Can you have DWV with low mite counts? Are a few deformed wings "acceptable or normal" ?
Thanks, Ray
