Field plots in stands of mature white spruce (Picea glauca (Moench) Voss) near Grande Prairie, Alberta, were treated for control of seed and coneinsects by soil application with carbofuran 5G at rates of 4.5, 6.7, and 8.9g/cm of tree diameter during late May to early June 1979. Cone and seedsamples were subsequently analyzed for insect species and abundance, insectcontrol, seed losses, and phytotoxicity.
This guide presents the principle components of seed orchard pest management, the development of a cone crop monitoring system, general guidelines and methods for monitoring, assessing impact, preventing and controlling cone and seed insects, the integration of cone management into a crop management program, and identification of damage caused by cone and seed insects of larch, pine, and spruce.
Regenerating British Columbia's Forests will assist those responsible for planning reforestation projects to reach informed decisions and will challenge them to consider primarily the biological factors basic to reforestation success rather than short-term costs and production technology. Although its main audience is practising foresters and forestry students of British Columbia, the text will be of considerable interest to foresters in other parts of Canada, the United States, and Europe who manage reforestation.
