Re: Tomato Horn Worn


Tomato hornworm is the larva of one of the Sphinx moths and not a polyphemus.
Polyphemus larva does not have the horn but does have tufts of black hairs
along its back and eats leaves of trees and shrubs such as oak, hickory,
maple, etc.

Tomato hornworm is most easily controlled by hand picking. It is frequently
parasitized by a wasp which lays white eggs on the body of the hornworm. If
you find one of the affected hornworms, do not kill it. The parasite will
take care of that and will help eliminate hornworms of succeeding
generations.

Where I garden in Zone 6 they have never been a serious problem  and I have
never used a pesticide for them. Hope they won't be a serious problem for
you, either.
