Role of winter-active aphids spreading Barley yellow dwarf virus in decreasing wheat yields in a Mediterranean-type environment

Deborah J. Thackray; Laura T. Ward; Monica L. Thomas-Carroll; et al. Australian Journal of Agricultural Research 2005. doi:10.1071/ar05048

Other claims from this paper (18)

Observation BYDV-RMV and CYDV incidence was mostly low.
Observation Rhopalosiphum padi predominated among aphid vectors.
Intervention effect Insecticide sprays killed or repelled aphid vectors and stopped further virus spread.
Observation Migrant aphids entered wheat throughout winter at both sites.
Observation Peak colonising aphids ranged from 0 to 99 per transect.
Observation BYDV-PAV incidence ranged from 0.1 to 58% of wheat plants.
Observation Wheat yield ranged from 1.9 to 8.6 t/ha.
Observation Aphids arrived earlier at Site A.
Observation Virus spread and associated yield losses were greater at Site A.
Intervention effect Starting insecticide sprays eight weeks after emergence increased virus incidence versus starting at emergence.
Intervention effect Starting sprays eight weeks after emergence increased yield losses versus starting at emergence.
Intervention effect Delaying sprays beyond eight weeks had no additional effect on virus spread.
Mechanism Early yield losses were attributed entirely to infection because aphids remained scarce until 8–10 weeks after emergence.
Association BYDV-PAV incidence explained 81 or 91% of yield gap variation at Site A.
Association Virus incidence explained 88% of seed weight variation.
Association Virus incidence explained 69% of protein content variation.
Association Virus incidence did not explain seed screenings.
Observation Late virus spread at Site B caused no significant yield or quality losses.
