Abstract
A nuclear-polyhedrosis virus disease of Spilonota ocellana (Denis and Schiffermüller) is described. The disease was found in the majority of the Nova Scotia apple orchards sampled in a nine-year survey. Under favorable conditions the disease caused high mortalities but usually less than 10 per cent of a host population was killed by the virus.Agathis laticinctus (Cresson) killed an average of 25 per cent of late-instar larvae.Keywords
