SPRUCE BUDWORM (LEPIDOPTERA: TORTRICIDAE) MOTH FLIGHT FROM NEW BRUNSWICK TO NEWFOUNDLAND

Abstract

Abstract Numerous spruce budworm, Choristoneura fumiferana (Clem.), moths were observed and trapped in western Newfoundland between 8 and 17 July 1982. At that time about 91% of the native Newfoundland budworm population was in the 5th and 6th instars and less than 1% had pupated. Spruce budworm moths probably emigrated with the aid of suitable weather from New Brunswick to Newfoundland.
