Book Description
In 1972 a field study of spruce beetle (Dendroctonus rufipennis) population dynamics was established in central British Columbia (BC) in two adjacent timber harvesting areas. Data from the 7-year field study was analysed with respect to the effects of spruce windthrow, stumps, and other logging residue on variation in the following factors of spruce beetle populations: adult emergence, adult size and sex ratio, brood development, and brood survival.--Includes text from document.
