Basic and applied studies on Douglas-fir beetle : spatial relationships of infestations, lipids and host habitat, and attraction distances of pheromone-baited traps

Creator:

Dodds, Kevin J.

Abstract:

Three studies on Douglas-fir beetle (DFB), Dendroctonuspseudotsuae, were conducted to investigate its basic and applied biology. Studies included investigations into the spatial relationship of DFB infestations over multiple years and multiple landscapes, relationships between DFB brood adult lipid levels and position of development along the length of tree boles, and...
