Eucalyptus trees

Post by Kate » Wed 11 Feb 2009 16:10

Can anybody give me any info about the disease that seems to have hit the Eucalyptus trees recently? On a walk this morning, I notice that many of them are dying (although new leaves seem to be coming through too) and I have heard that they have been struck by something nasty this year but I can't seem to find out what!!

It's an insect, Kate. The trees, unfortunately, won't recover. Will get you the name if you want?

Kate,
Apart from Koala the main health problems of the trees is a disease known as Leap Psyllid, which eats away at the bark and causes the tree to slowly die.

There is no cure for this and the other problems with Eucalyptus, there is hope in the future to have some systemic spray but this is a future job.

This insect - and also the illness that affects Plane trees - actually came into France on weapon boxes during the second world war, apparently :?

Thanks everybody
I was going to do a bit of an article on it, as I was so amazed to see these poor dying trees up in Llauro yesterday, but I can't find much on the 'net. That is fascinating Thumbs about the weapon boxes. Any idea where I can find out more?? Is the Leap Psyllid that Pads talks about the name of the insect?

It looks to me as though it might be properly called a Lerp Psyllid, but as its nests are known as leaps, it also has that name. Or does it leap around...maybe. It also seems that a researcher whose surname is Leap has written material on it.

I googled Leap Psyllid, and was asked if I meant Lerp Psyllid - THEY'RE asking ME??!! :lol:
