The Final Technical Report is comprised of the enclosed four parts: Part A: 'Landscape Level Hazard Rating for Western Blackheaded Budworm in British Columbia'. Part B: Title page and abstract (with Thesis Committee Membersí signatures), and the table of contents of the M.Sc. Thesis 'Development of a Western Hemlock Looper, Lambdina fiscellaria lugubrosa, Hazard Rating System for Interior British Columbia using Discriminant Function Analysis and Logistic Regression', successfully defended by Neil Borecky at the University of Victoria. Part C: 'Monitoring Western Hemlock Looper Populations in British Columbia'. Part D: This is the forest tent caterpillar component of the project and is comprised of the following subsections: D1: A PowerPoint presentation on the 'Stand Level Hazard Rating for the Forest Tent Caterpillar (Malacosoma disstria) and Predicting the Probability of Occurrence of Future Outbreaks.' The talk summarizes the work done on the Forest Tent Caterpillar from the landscape to the stand level. The stand level hazard rating is much more useful to forest managers in their efforts to minimize impact of this defoliator. This talk given at the Pacific Forestry Centre to its personnel and visiting forest entomologists from the BC Ministry of Forests will also be written up as a scientific publication and will be made available to people interested in the management of this insect. This is mostly based on the work we did on developing stand level and risk rating for the forest tent caterpillar (an important pest mainly of Populus spp.) in the Prince George Forest District where most of the outbreaks occurred in the past.
