| Summary: | The black-headed budworm has long been known as an endemic resident and occasional epidemic defoliator of coniferous forests in Canada and parts of northern United States. The moth is distributed across the whole of the northern forest area from Cape Breton Island to the west coast of Canada and Alaska. It is a serious and recurrent defoliator particularly in British Columbia and Washington (Silver, 1960). The larvae feed on various conifers of the genera Abies, Larix, Picea, Pseudotsuga , and Tsuga , and different hosts are preferred in different parts of the range. Thus, Schaffner (1950) gives Abies balsamea as the most important host in eastern areas, Raizenne (1952) indicates that species of spruce ( Picea ) are most often utilized in southern Ontario, while Tsuga heterophylla has been found to be preferred in coastal British Columbia (Leech, 1933; Keen, 1952; Evans and Silver, 1954; Silver, 1960). |
