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.
Did you cut off the limbs that completely died first?
Yes but tree died anyway, it suckered from ground and i regraft. No late frost again this year and no beetle damage on any trees.
One of mine just got hit. I’m gonna wait it out and see what happens. I did however spray all the trunks with permethrin to prevent them.
Do they attack all year long?
For me only in spring. Did you have a late frost (freeze after leaf out?)
Nope. I’m in NE Ohio and we did have a late frost but only for the peaches. Pawpaw were still all bare. I had. I had no idea about AB until recently so now I’ll just spray every tree every year as a precaution.
Do permethrin early in the year then switch to maybe cedar oil or one of the other pyrethin sprays.
THANK YOU for this link. it’s a long presentation but i found the damn critter and want to understand it. Ethynol traps will be going up.
I have a lot of figs and dealt with AB as below
Ethanol traps for surveillance
If no AB then no perm spray
If trays with bugs or frass seen then all my trees get perm spray on trunks weekly until the Ab attacks cease
It’s usually early spring around the time my Bartlett pear blooms
THANK YOU too for chiming in. “perm spray” i take it to be Permethrin? and do you use Siven on trunks weekly? if not, what brand?
I use the below from Amazon in my backpack sprayer because I have a lot of trees. AB has a specific attack pattern: they don’t go very high up the trunk/branches. It’s good to not spray all over the place because this stuff isn’t good for the environment.
I use the traps to attract and kill AB. I use this spray to dissuade attacks on trees I am protecting. I personally cut and burn anything that already has attacks that I didn’t catch right away to not allow any further breeding on my property. If you have a bad year then it’s good to search all your trees. I had a dogwood that likely had AB as a potential source. I kept watching my fruit trees and may have had a source right under my nose…it quickly because firewood
your feedback was on-point and much appreciated. thank you Drcampbellicu!
