Abstract

A nuclear polyhedrosis virus was disseminated into field populations of an incipient outbreak of the forest tent caterpillar, Malacosoma disstria (Hübner). Mortality varied with the concentration of virus used and the age of larvae at the time of spraying. Larvae showed symptoms of infection more rapidly when sprayed with the higher concentrations and secondary infection and mortality occurred in areas where initial mortality developed during the early larval stages.
