Great, thanx Bronwyn.

It's local knowledge like that is priceless, as all the sites are
non-commital about pesticides. We've 3 CPs and 4 pencil pines, plus a couple
of other pines of a turquiose colour foliage. These pupae are wreaking havoc
on the CPs, I'll probably lose 2 of them. They are also on the other pines,
but in lessor numbers.

I dont think I'd get pines again, as they have suffered other less drastic
borer attacks regularly, one pencil pine was cut-off like a saw last year.
Come outside one morning and its half the height :-)
The butt-end had a nice circular channel eatern out of it.

Thanx again, Jason

G'day Jason

Think I'd be using something like Maldison which is available at Coles
or Woolies supermarket under the label 'Crawly Cruncher'. Around $6.00
for a litre refill bottle, slightly more if you want the spray bottle.
Any old spray bottle can be used, BUT do follow safety precautions on
the label and only wash in COLD water on completion (hot water opens the
pores).

Also spray the ground to the dripline so new infestations will be
stopped in their tracks.

Hope this helps?
Bronwyn ;-)

I don't know what you have, but when I get a similar problem with other
trees, I get a good liquid poison and a pump up sprayer, and spray them.

We

have what is called a web worm. When sprayed, they immediately fall out

of

the web on the ground and die in a couple of minutes. You can find one

that

will also kill the pest after being eaten with the leaves. Good luck.

Thanks for those comments, Dwayne. These appear to emerge from the
foliage
(we've got Cypress pines), form a cocoon, some drop to the ground by a
thin
thread of a web-like substance. They then move across the ground to
other
pine trees, they are quite quick travellers. They withdraw into their
cocoon
on the slightest vibration.

Others stay on the tree and destroy the foliage and then the branch
dies.

From the Canadian forestry site, they look closest to a Sawfly of some
sort.

Thanks for the tip. All I can do is checkout the products available.
Manually killing them is like trying to bail the ocean out with a
bucket.
