We have attempted to condense the present literature and supplement it with our own observations in order to prepare a manual that should facilitate identification of budworm parasites and estimation of parasitism levels. Most of the parasites treated in this manual are also found in other areas of the Northeast, and some range as far west as British Columbia. However, it should be emphasized that the keys in this manual may not be applicable to areas other than Maine.
