Yes, first saw it in nectarine mid-September two years ago. Very ripe, but
intact fruit still on trees. SWD love damaged peaches, try to get them all
picked before they get too soft. I was in a peach orchard recently where
the grower had too many peaches to sell. Many soft ones left on trees, and
many on ground -- loaded with SWD. This year has been like nothing I've
ever seen with these little guys...
