Other claims from this paper (13)
- Association Spring and summer alate Myzus persicae were the strongest predictor of beet yellows spread.
- Observation Apterous M. persicae spread little beet yellows virus.
- Observation Alate and apterous Aphis fabae contributed negligibly to beet yellows spread.
- Method / resource A spread model adequately fit observed beet yellows infection using trap counts and assumed aphid parameters.
- Observation Yellows spread mainly within or among nearby fields after spring introduction.
- Observation Summer migrants from infected seed crops spread some infection to root crops in intensive seed crop areas.
- Mechanism Greater yellows prevalence in seed crop areas was attributed to greater M. persicae infestation.
- Observation The proportion infected by spring migrants before June end was small and variable.
- Association Initial infection did not differ significantly between seed and nonseed areas.
- Observation Mosaic spread mainly near seed crops within seed crop areas.
- Association No significant aphid number relation with mosaic infection increase was established.
- Observation The authors suggested both aphid species spread mosaic equally.
- Mechanism Variation in seed crop infection and migrant origin was proposed to explain irregular mosaic incidence data.
