Population dynamics of the major north American needle-eating budworms. Forest Service research paper
Technical Report
·
OSTI ID:5891824
The report includes data from six western States provided 1,251 life tables representing western spruce budworm, Choristoneura occidentalis. These data provided projection capabilities for defoliation and successive budworm densities, as well as a basis for comparing survival rates among the three principal North American needle-eating budworms (western and eastern spruce budworms, and the jack pine budworm). Several modifications are suggested in current methods for managing budworm susceptible forests, and suggestions are provided for further studies on the budworm life systems.
