Winter Moth, Again?
The time has just ended for a round of winter moths flying around exterior lights in Eastern Massachusetts. There is no need for fall treatment sprays, the best idea is to either inject the trees in the fall or early spring with a two year control material, or wait until the leaf has unfurled and treat the foliage with a foliar spray. Fall sprayings have very limited benefit. The numbers of Cyzenis albicans, a Tachinid fly that parasitizes only winter moth, have been rising since they have been introduced and will continue to provide a natural predatory control.
