Abstract

The susceptibility of gypsy moth (Lymantria dispar) to the gypsy moth nuclear polyhedrosis virus was significantly altered when larvae were fed virus in conjunction with diets containing different nutrients and plant allelochemicals. Larvae consuming virus on diets with additional sucrose, surfactants, or gallic acid showed no significant changes in mortality rates. Larvae consuming virus on diets with additional casein or salts, on diets made more acidic with HCl, or on diets containing hydrolyzable or condensed tannins showed up to fourfold significant decreases in susceptibility to gypsy moth virus.
