About a year ago I asked about Worms in my pears in:
http://groups.google.com/group/uk.re...a59d3da0b8de42

The diagnose wasPearmidge.
I tried to catch the falling pears in a net. But it was of no use
since most of the maggots had already left the pears.
I also covered up the ground and found a significant number of maggots
dead on the cover.
Unfortunately I got some heavy rain so some of the maggots was flushed
of the cover.
In addition to this I covered the ground in the spring, if it made any
difference I don't know.
All this seemed to make a difference, the ratio affected to unaffected
pears was significantly lower this year.

But unfortunately, we had bad pollination this spring so the number of
unaffected pears are low too.
I did no see a single bee in the tree this spring, just some
bumblebees, I think I have to find a
beekeeper and ask him to move some hives to our neighbourhood.

Thanks for the update, we have suffered for years on onepeartree but
not the other, timing it seems is all.

I think the best method is to cut the grass below the tree short.
Cover the ground with something that let the rain and the light
through so that
the grass don't suffer, and to minimize the possibility that the
maggots
will be flushed of the cover. Maybe some old bed sheets might do.
Trying to catch the falling pearlets I think is of no use.

About the timing. How do the midgets "know" when the right( wrong)
time is due.
Temperature in the ground ?? or ??
Maybe it is possible to fool the midgets to emerge at the wrong time.
Either by covering the ground with transparent plastic to create
a "greenhouse" and make the ground warmer, or by covering the
ground with old leaves or similar to make i colder. Wdus ?
