I only have about twenty trees and am surrounded by woods. I believe
that the curculios come in from the woods, where they overwinter, so
applying nematodes here would do no good on that generation. Perhaps
Neem would do something, but I consider it pretty much of a regular
pesticide (vs. a physical deterrent, like Surround). Neem is a
feeding deterrent and insect growth regulator so may have no effect
on curculio because the damage comes from the adult female laying an
egg inside the fruit,
