Abstract
During the past decade a severe outbreak of budworm has been in progress on jack pine in northwestern Ontario, following similar infestations in Michigan and Minnesota. It has been observed that budworm on jack pine does not spread to adjacent stands of balsam fir and spruce, and similarly that outbreaks on fir and spruce do not spread to adjacent jack pine stands.
