Population Dynamics of the Major North American Needle-Eating Budworms (1993)

Problem Addressed: Western Spruce Budworm
Goal(s)/Objective(s): Analyze data from nine projects in six western States to provided 1,251 life tables and to produce projection capabilities for defoliation and successive budworm densities as functions of preceding density, site and stand attributes, interested influences, systematic year-to-year changes in survival, recent insecticide treatment, and weather.
Key Findings: The predator-limitation theory of Hairston and others (1960) is not adequate to explain population limitations in this group of herbivores
