Abstract
Gypsy moth (Lymantria dispar) developmental interactions with two hybr id Populus species clones were studied in laboratory trials. Significa nt differences in larval performance were found between clones and wit hin the same clone at different phenological states. No larvae were ab le to complete development on clone NM6. All gypsy moth larvae feeding on clone NC5271 survived when leaf flush was synchronized with gypsy moth eclosion in early May. However, neonates feeding on NC5271 foliag e in July experienced increased mortality. Weights of surviving gypsy moth larvae feeding on NC5271 foliage in May versus July were not sign ificantly different.
