Published online by Cambridge University Press: 31 May 2012
Extract
A polyhedral disease was discovered to be one of the natural agents attacking the black-headed budworm, Acleris variana (Fern.) in the coastal region of British Columbia during the outbreak of this insect, 1940-45. This disease became the most important single factor contributing to the decline of the outbreak (Prebble and Graham 1). The present report includes observations on some of the symptoms and microscopic characteristics of the disease.
