| 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 |
| location of the mechanism of resistance to amphorophora agathonica (hemiptera: aphididae) in red raspberry. | the aphid amphorophora agathonica hottes (hemiptera: aphididae) is an important virus vector in red (rubus idaeus l.) and black (rubus occidentalis l.) raspberries in north america. raspberry resistance to a. agathonica in the form of a single dominant gene named ag1 has been relied upon to help control aphid-transmitted plant viruses; however, the mechanism of resistance to the insect is poorly understood. aphid feeding was monitored using an electrical penetration graph on the resistant red ra ... | 2012 | 22928330 |
| a genetic linkage map of black raspberry (rubus occidentalis) and the mapping of ag(4) conferring resistance to the aphid amphorophora agathonica. | we have constructed a densely populated, saturated genetic linkage map of black raspberry and successfully placed a locus for aphid resistance. black raspberry (rubus occidentalis l.) is a high-value crop in the pacific northwest of north america with an international marketplace. few genetic resources are readily available and little improvement has been achieved through breeding efforts to address production challenges involved in growing this crop. contributing to its lack of improvement is l ... | 2015 | 26037086 |
