Western larch resistance to Douglas-fir beetle attack

Creator:

Neal, Tiffany A.

Abstract:

Live western larch, Larix occidentalis Nutt., a tree species resistant to the Douglas-fir beetle, Dendroctonus pseudotsugae Hopkins, produces the monoterpene 3-carene in higher concentrations compared to Douglas-fir, the preferred host of D. pseudotsugae (Reed et al. 1986). The inhibitory effects on attraction to aggregation pheromones and toxicity of 3-carene to...

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...
