Documentation of Pinus sylvestris of which the cambium was killed by the rhizomorphs and melanine plaques of Armillaria ostoyae after which the bark was thrown.

Don't think I've noted that before.

 

Thanks Gerrit.

 

 

Do you know which beetles/wasps have created the holes?

David,

No, I don't. I only visited these woods with pine, birch and oak on poor sandy soil yesterday, to demonstrate the colonizing strategies of fungal pathogens on pine and other trees to the Dutch participants of one of my seminars and workshops on MTA.

Interesting!

looks like Sirex ( wood wasp) holes to me.. especially if on the south facing aspect.

That's interesting Peter.

 

I wondered what these emergence holes & grubs were on a dead Pine at my work site last year.

 

I thought at the time they may have been Banded Pine Weevil

Perhaps they were Sirex ?

 

Didn't note any Armillaria in evidence.

First look at your photo of the larva and I’m thinking that looks just like Longhorn!

However, hole through the bark doesn’t look like longhorn. How deep were the tunnels in the wood? any more photos? did you keep any insects?

 

Sorry: more questions than answers I'm afraid

Didn't measure the holes.

Kept one grub, but it vanished.

 

Some additional photos on another thread somewhere, I'll have a search for it & resurect it to leave this one on track for Gerrit & his Armillaria

I'm actually shocked that you don't have an affectionate fungal type nickname for your good lady
