Laboratory and field tests revealed the possibility of infecting larvae of Hyphantria cunea Drury with the nuclearpolyhedrosis virus of Thymelicus lineola (Ochs.). H. cunea is highly susceptible to the action of this virus, particularly the second instar larvae where mortality reached 100%. Virus infected larvae of H. cunea showed the same symptoms of infection as those observed on the original host, T. lineola. Several problems still have to be elucidated, namely to determine whether T. lineola or H. cunea is the primary host as both species often live in the same phytocenosis.
Des essais en laboratoire et dans le champ démontrèrent la possibilité d’infecter les larves d’Hyphantria cunea Drury avec la polyédrose nucléaire de Thymelicus lineola (Ochs.). H. cunea est très sensible à l’action du virus, particulièrement les larves de IIe âge chez qui la mortalité atteint 100%. On retrouve chez les larves infectées d’H. cunea le même syndrome d’infection que chez T. lineola.
