This book was released on 1997 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The large aspen tortrix (Choristoneura conflictana) is an occasional defoliator of trembling aspen (Populus tremuloides) in western Canada. Research suggests that there might be a narrow phenological window for successful tortrix colonization of aspen buds in the spring. This paper adapts a stochastic model to describe the temporal relationship between C. conflictana and trembling aspen phenologies. The first characterization of the phenological stages occurring during bud-break and leaf expansion of trembling aspen is provided, as determined from observations at two sites in 1994. Degree-day models based on a common threshold temperature are developed for both insect and bud and shoot development of its host. The influence of changes in the sequence of temporal events on the success or failure of tortrix populations is also discussed.
