Wood Borers

Al H.

G'day all.
I have lost a Gippsland Mallee (E. Kitsoniana) to wood borers.
I have a Red Box (E. Polyanthemos) that is being eaten under the bark quite severely as other species of Euco.
I have done a search on the internet with out any luck on this subject unless it is milled timber.
My smooth bark trees like the Spotted Gum (E. Maculata) don't appear to be attacked.
Any info as far as treatment for these pests would be greatly appreciated.

Borers generally attack stressed trees.

The trees self defence to borers is to drown them with sap/resin/kino ... in stress conditions trees unable to perform that task.

Very hard to kill borers with chemicals, high dosage of confidor required, basal drench or injection.

That tree in the second pic looks like it had mechanical damage in the first place.

Thanks Eric.
No mechanical damage what so ever.
All the tree's being attacked by borers are starting to look like this.
I'll look into those tips mentioned.

Thanks.

Sure does look like it copped some sort of a wound in that area in the past.

Down low like that i would suggest maybe equipment like a ride-on mower gave it a bump maybe???

Poke some coathanger wire in the holes and stab the buggers

Often with mechanical damage the bark stays in tact over the wound and the borers are going to town beneath hidden from eye sight.

In this thread you'll see an example, but damage was from sunburn.
