Aw man, I’m sorry to hear that. I was just out putting up traps and spraying trunks with pyganic recently as a preventative due to the frost here several days ago.
Let me know if you need any Wabash scion wood or any other varieties and I’ll send em to ya right away.
For y’all who have had repeated attacks, are your trees surviving? I see above at least one case of that.
I may have been too hasty but I’m pretty sure it was toast and the damage was low on the trunk, affecting the whole thing.
Thanks Tony!! Will let you know 
PS I’m not thinking through some of my posts as I’m Uber busy with work lately LOL
I haven’t had any pawpaws get hit as of yet, but my Prok persimmon got nailed by them in 2020 after a May freeze killed all its new growth. I didn’t count all the holes, but there were at least several dozen throughout the trunk. It took maybe a month to show life again, but it bounced back with a vengeance. Prok was and still is my strongest grower and largest fruit tree, so if any of my trees could’ve bounced back from that it was Prok. I also had 2 potted apples get hit that same year. It was just 1 or 2 holes in the lower trunk of each. 1 of them died and the other survived and was relatively unphased.
Well rats. I may have just needlessly whacked a good tree (though again it had some serious crown damage but was seemingly outgrowing that. Still, long term viability may have been suspect.)
Did you spray to kill the beetles on your Prok or just let nature take its course?
No, I didn’t spray Prok that year. I didn’t even realize what had happened until later that year. I had just thought that it was taking a long time to grow back from the late freeze damage lol.
I’m not sure what the best decision is. I know I would be more concerned and likely to chop it down if one of my pawpaws got hit than a vigorous American persimmon. At least the rootstock might be salvageable if you cut it down soon enough and you can regraft.
