t0“Barley yellow dwarf virus Serotypes in Barley Fields”
e1“Population dynamics of Padi avenae (PAV), Macrosiphum avenae (MAV), and Rhopalosiphum padi (RPV) virus serotypes of Barley yellow dwarf virus (BYDV) and of their main aphid vectors were studied in winter barley (Hordeum vulgare) fields”
e4“The occurrence and spread of PAV and MAV serotypes in the field was clearly and easily related to that of their main vector species”

Other claims from this paper (9)
- Association A model of BYDV spread accurately simulated the epidemic kinetics of PAV serotypes in barley fields.
- Association The BYDV model results were less satisfactory for RPV and, to some extent, for MAV serotypes.
- Association Spread of RPV serotypes showed no consistent relationship with the dynamics of their vectors.
- Observation PAV incidence in barley showed a bimodal distribution, with maximums in fall (December) and spring (May).
- Association PAV incidence in barley was linked to fall infestations by R. padi and spring infestations by aphid species.
- Association MAV incidence in barley reached a maximum in spring 1990 and 1991, related to S. avenae and M. dirhodum occurrence.
- Association RPV incidence in barley was low every year despite the abundance of its aphid vector.
- Association Mixed BYDV serotype infections in barley were more frequent than expected by chance.
- Mechanism The authors hypothesise that mixed BYDV infections are partly related to heterologous encapsidation.
