Resumen:
We were able to reconstruct outbreaks of WSB by comparing patterns of growth in host trees and non-host trees. We confirmed one known outbreak period and detected seven additional undocumented outbreaks (six occurred pre-1950). The frequency and duration of detected outbreaks in our study is consistent with known population cycles of WSB (Campbell et al. 2006), however, the intensity of the most recent outbreak was greater than all those previous within our study period. Preliminary climate analysis suggests that reduced ring width is correlated with increasing drought severity in early summer. Therefore, drought stress may be associated with increased susceptibility to WSB infestation in Douglas-fir.
