Epidemiology of Barley Yellow Dwarf: A Study in Ecological Complexity
Investigating virus variants, their plant hosts and vectors, and elucidating the confounding resultant interactions in diverse and fluctuating environments in different regions of the world is an extremely difficult task, but one that must be undertaken to gain an understanding of the pathosystem.
A method for quantifying biodiversity loss and its application to a 50‐year record of deforestation across Madagascar
Madagascar is a top global conservation priority for high rates of deforestation and endemism. Deforestation has been extensive, but impacts of forest loss on biodiversity have not been well
Long-range aerial dispersal of cereal aphids as virus vectors in North America
It is concluded that long-range dispersal has received inadequate attention in relation to its biological and economic importance.
Aphid Attraction and Preference for Soybean and Pepper Plants Infected with Potyviridae
The objective was to determine whether color or odor-mediated cues of plants infected with Potyviridae mediate aphid attraction, and it was found that Myzus persicae and Rhopalosiphum maidis preferred alighting on intensely yellow than on green or brown ceramic tiles, and expressed no preference for landing on leaves infected with soybean mosaic virus.
Physical and Biological Perturbations: Their Effect on the Movement of Apterous Rhopalosiphum padi (Homoptera: Aphididae) and Localized Spread of Barley Yellow Dwarf Virus
Apterous adult and nymphal Rhopalosiphum padi (L.), previously reared on plants infected with barley yellow dwarf virus (BYDV), were subjected to eight perturbations to determine effects on aphid dispersal and pattern of local spread of BYDV to oats in greenhouse experiments.
Coupling Disease-Progress-Curve and Time-of-Infection Functions for Predicting Yield Loss of Crops.
The model was expanded to predict L when there was spatial heterogeneity in disease incidence among sites within a field and when maximum per-plant yield loss occurred at a time other than the beginning of the epidemic (t > 0).
