Abstract

Surveys in unsprayed apple orchards indicated that the oriental fruit moth, whose principal hosts are peach and apple, does not occur in continuing populations on apple beyond the range of commercial peach orchards in Ontario. Moths released in an apple orchard 25 mi from the nearest peach orchard did not result in an infestation after the first winter. High winter mortality due to low temperatures and the unsuitability of apple for the first generation of the moth probably are the main reasons it does not establish continuing infestation on apple alone.
