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...

Lodging control and yield enhancement in Morex spring barley with paclobutrazol treatment

Creator:: Morrison, Laura A.
Abstract:: Lodging in cereals can cause significant decreases in yield. It is both a problem in susceptible cereal cultivars with a tall-stemmed, weak-strawed growing habit and in lodging-resistant cereal cultivars when they are grown under high-nitrogen, high-moisture regimes. Plant growth regulators (PGR's) are chemical growth retardants that offer a method of...

Status, distribution and seasonal variation of filbert aphid resistance to selected insecticides in the Willamette Valley, Oregon

Creator:: Katundu, Juma
Abstract:: Levels of resistance to six selected insecticides of eleven field populations of the filbert aphid Mvzocallis coryli (Goetze) were determined by using the leaf-dip residue technique. Test insecticides included compounds widely used in commercial filbert orchards, namely, carbaryl, diazinon, endosulfan, phosalone, fenvalerate and oxydemetonmethyl. Aphid samples were collected within a...
