Estimates of gypsy moth (Lepidoptera: Lymantriidae) mortality at two sample heights following application of gypsy moth nuclear polyhedrosis virus

Estimates of gypsy moth (Lepidoptera: Lymantriidae) mortality at two sample heights following application of gypsy moth nuclear polyhedrosis virus

Larvae of Lymantria dispar were collected from understorey/lower canopy and from mid- to upper-canopy foliage of an oak (with Hamamelis virginiana understorey) forest, in Maryland in May 1994, that had been treated with nuclear polyhedrosis virus (Gypchek) 4-5 days before. The larvae were then maintained for 4 weeks and studied. Larval mortality was recorded weekly and cadavers were examined for viral occlusion bodies.

Gypchek, as the LDP226 strain of the nuclear polyhedrosis virus of the gypsy moth, Lymantria dispar (L.), was compared in small forest plots with the Abington isolate (Pass 10), each at three dosages. Also evaluated were one dose of virus produced...

Cross-infections of L. dispar by a nuclear polyhedrosis virus of O. antiqua (OaNPV) showed that there is not only a dosage-related, but even an absolute difference in susceptibility to the virus depending on host races. The passage of the virus st...
