Amphorophora agathonica (Hottes) is the primary vector of aphid-transmitted viruses in red raspberry in the Pacific Northwest region of the United States. To better understand the biology of the aphid, we estimated the lower developmental threshold and studied the seasonal activity of A. agathonica in commercial fields in northern Washington...
Cocksfoot mottle virus (CfMV) is a mechanically and beetle-transmitted, non-seedtransmitted
sobemovirus associated with orchardgrass (Dactylis glomerata L.) stand decline
in Europe, Japan, New Zealand (Mahy and Van Regenmortel 2010), and Canada (Bittman
et al. 2006). Additional hosts, reported from New Zealand (Delmiglio et al. 2010), include
Festuca novae-zelandiae, Lolium spp.,...
This publication reviews the growth stages of grapes. For each growth stage (or group of growth stages), the document lists the more effective pesticides used to control insects and disease, their rates, and application timing for Oregon grape growers. It also covers the effectiveness of various fungicides for control of...

The present study examined involuntary attentional bias toward facial emotion expression. Particularly, the study examined two different attentional components for emotional processing, namely, orienting vs. disengagement. A cueing paradigm using two cue presentation times (250ms and 350ms) was used to determine if attention would be involuntarily captured by an irrelevant...
I. REPRODUCTION AND LAMB PRODUCTION Relationships among hemoglobin (Hb) genotypes and reproduction and production traits were examined in 294 four- and five-year-old North Country Cheviot, Dorset, Finnsheep or Romney x Suffolk or Columbia-type crossbred ewes. Hb BB ewe lambs were youngest at first estrus and Hb AA ewe lambs were...
The interaction of basalt melt with mantle harzburgite at low pressure might result in silica enrichment of the melt by assimilation of orthopyroxene. Experimental tests of this hypothesis show that silica-rich liquids (56 wt %) are produced by melt-orthopyroxene reaction at 1200° to 1250°C. These silica-rich liquids are enriched in...
