The Spruce Budworm and the Spruce Coneworm: Behavior on Red Spruce and Insecticide Efficacy

Problem Addressed: Spruce budworm and spruce coneworm damage to red spruce in Maine
Goal(s)/Objective(s): Study of feeding and concealment behaviors of spruce budworm, and spruce coneworm, on red spruce in Maine in 1984.
Key Findings: Feeding and concealment behaviors were similar for both species.

Parasitization of the spruce budworm, Choristoneura fumiferana (Clemens) (Lepidoptera: Tortricidae) by Brachymeria intermedia (Nees) (Hymenoptera: Chlaciddidae)

Problem Addressed: Spruce Budworm
Goal(s)/Objective(s): Study the use of the parasitoid Brachymeria intermedia to attack spruce budworm
Key Findings: The percentage mortality is considerably higher than the total native pupal parasitoid complex.

Dendrochronological reconstruction of spruce budworm outbreaks in northern Maine, USA

Problem Addressed: Detection of major spruce budworm outbreaks in Maine
Goal(s)/Objective(s): Reconstruct the history of major spruce budworm outbreaks in northern interior Maine using host–nonhost dendrochronological analyses, contrast the outbreaks detected in this region to those of eastern Canada; and evaluate the efficacy of using radial growth patterns of small spruce trees for the purpose of detecting outbreaks.
Key Findings: Small-diameter, slow-growing red spruces clearly express the typical budworm signal once ring-width data have been properly standardized.
