Cicada Damage

[cspot]

Well I didn't realize it until now, but Cicada's will damage trees especially young trees. They got all of my pear and chestnut seedlings that I put out last year. I pruned off the heavy damage and I hope they will rebound. I guess time will tell. I only pruned what was dead off, but there is still some heavy damage done below that.

Here is a link to what they do.

They hit my Sawtooth Oak pretty hard. I planted them about 6 years back, prolly around 15' now. I've got major damage to all the branches. I'm going to do some serious pruning once the plague is over.

I noticed tonight Bush that the noise is quieted way down and there isn't near as many flying around. I think they are getting about done. I think someone said they are supposed to be done by the 4th of July.

I don't have any in my area. 3 years ago we had them bad.

It was crazy loud yesterday out in Burgettstown. They where everywhere on every tree. I was brush hogging a field edge and was covered with 100's of them.

Yep. They were still bad last night, but today there is a huge difference. My wife noticed the same thing as I did. Still around but not near as many.

Ok, shouldn't the roots of those trees still be intact and able to shoot out new growth?

When we had them bad here years ago, they damaged to ends of branches on oaks, but it was just temporary.

I was doing some bowfishing around Canonsburg over the weekend and the noise was deafening. Darn things were crawling everywhere. Just 5 miles north of there, nothing.

What has me concerned is these are seedlings that have been in the ground for a year or less. The stress that this will put on them may do them in or make them susuptible to disease. An established tree should be fine. Also since these are small the damage goes almost the whole way to the ground.

I forget exactly what happened to my chestnuts some years back, but, a couple of them, I cut the stem off and it sent up a new main leader. Tree is now fine.

I am hoping mine do the same.


Here is a map of what brood and the year they emerge.

Pruned all the damage off of 25 sawtooth oaks today. Some of them were still covered with the dang things!!!!

Dave and I were at the cabin last week, and the cicadas were pretty noisy. The map above in cspot's post seems to show that the edge of the territory in PA would be either Greene or Fayette County. I suspect that the brood has expanded a bit to the east into the western edges of Somerset County, because Dave and I know for sure they were around the cabin, but down in Confluence and Ursina we heard next to nothing.
