| aroma extract dilution analysis of cv. meeker (rubus idaeus l.) red raspberries from oregon and washington. | the aromas of cultivar meeker red raspberry from oregon and washington were analyzed by aroma extract dilution analysis. seventy-five aromas were identified [some tentatively (superscript t)] by mass spectrometry and gas chromatography-retention index; 53 were common to both, and 22 have not been previously reported in red raspberry. twenty-one compounds had an equivalent odor impact in both: 2,5-dimethyl-4-hydroxy-3-(2h)-furanone, hexanal, 4-(2,6,6-trimethyl-1-cyclohexen-1-yl)-3-buten-2-one, (e ... | 2004 | 15291490 |
| predatory role of neoseiulus fallacis (acari: phytoseiidae): spatial and temporal dynamics in washington red raspberry fields. | the seasonal abundance of spider mites and their predator neoseiulus fallacis (garman) (acari: phytoseiidae) was determined during three consecutive years in washington state red raspberry fields. tetranychus urticae koch (acari: tetranychidae), eotetranychus carpini borealis (ewing) (acari: tetranychidae), and n. fallacis were commonly found in skagit and whatcom counties. e. carpini borealis colonized the fruiting canes earlier in the season than t. urticae. the two phytophages overlapped in m ... | 2002 | 12539824 |
| seasonal phenology of amphorophora agathonica (hemiptera: aphididae) and spread of viruses in red raspberry in washington. | 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 state. in addition, we monitored the spread of raspberry viruses (raspberry latent virus and raspberry leaf mottle virus, rlmv) to determine how rapidly fie ... | 2014 | 24763099 |
