I found it interesting that Washington State University was experimenting
with wild multiflora roses to encourage parasitic wasps. In Ohio Louis
Bromfield championed multiflora roses but they developed into a pest plant
that was hard to control. How is the spreading of these plants being
controlled?

I have Multifloras on my farm. Since I grow organically, I'm interested in
the possibilities of insect control that may be coming from these wild
roses. How can I determine the roses effect on encouraging parasitic wasps?

Reading the full article mentioned in Lon's posting, I found that although
Rosa multiflora is mentioned more prominently, the first rose that was found
to be hosting the wasp's prey was our friend R. woodsii, the native with
very tasty hips. The researchers are investigating many other rose species
too.
