Other claims from this paper (9)
- Observation Most aphid samples were on dryland wheat and few on irrigated wheat.
- Observation Volunteer wheat and rescue grass were preferred alternative hosts for all three aphid biotypes.
- Observation No RWASA1 samples were found on oats.
- Observation RWASA2 survived on oats, where 12.26% of its samples were collected.
- Observation Wild oats held 2.83% of RWASA2 samples.
- Observation All tested hosts supported positive population increase for all three aphid biotypes.
- Observation RWASA2 and RWASA3 population increase was significantly lower on resistant TugelaDn5.
- Observation RWASA2 and RWASA3 increased significantly faster than RWASA1 on oats and wild oats.
- Recommendation Management planning should account for aphid biotype success on alternative cereal hosts.
