<pre>We have 2000 newly planted trees in the Margaret River region of Western
Australia and are constantly at war with grasshoppers which are blown in
from adjoining pasture land. We seem to be constantly spraying them with
pesticides. which limits them for a week or two. Is there anyone on the
list who may know of a less toxic way of dealing with the problem? Along
with the grasshoppers is another new pest which I'm told is called a
Rotherglen Bug. Does anyone have any info on how to combat this one in a
less toxic manner.

At first we thought we had lost about 140 trees which had been defoliated
and the barks scarred. The trees are proving quite hardy thank goodness
and are starting to come back with a vengeance so our losses will be
restricted to about 40 trees.

Good Luck to All

To fight olive fly one of our producers "enveloped" some trees with nets
used for harvesting.
The result was very good, even if flies are smaller than grasshoppers.
Maybe it's a bit expensive if you don't use nets, but surely is healthier
than pesticides.

Hope this helps!

<pre>And a lovely place Margaret River is too. Better known for its excellent
wines but they say good grapes and good olives grow well together.

The 'Rutherglen Bug' you have identified is more a pest of wine grapes than
olives but it would be interesting to hear if the bug is doing damage to
your olive trees. There is an olive lace bug that attacks olive trees (see
Olives Australia web site for newsletter Issue 9, November 1998) for further
details and possible remedies. Details of Olives Australia website available
on request. Hope the bugs don't go walkabout across the Nullaboor and head
East.

Regards,

Phil

<pre>Try spraying your trees with fish emulsion.The smell may well deter
grasshoppers from eating the tree leaves.It is effective on possums and
rabbits so may well work.Spray at least every 10-14 days.

<pre>Several groves in Southern Tablelands (NSW) have suffered from
grasshoppers this summer. Only a small proportion of our trees have
had leaves eaten but others not so lucky. Does anyone have a
solution please?

<pre>The grasshopper problems should stop with more rain the grasshoppers are
only feeding on Olives as a last resort. It has been an extremely dry summer
and their natural food source has been extremely limited.

<pre>Sweton, the time honoured Margaret River organic solution to the grasshopper
problem is guinea fowl.
As an extra benefit to becoming a guinea fowl owner, you may, I hope, be
motivated to implement some fox control, if you're not already doing so, in
order to maintain the guinea fowl status quo.

Nett benefit all round.
Cheers,
Margaret.
