Other claims from this paper (12)
- Observation S. alba x B. napus lines resisted weevil feeding and oviposition.
- Observation Weevil larvae on the resistant cross lines were fewer and lighter and developed more slowly.
- Intervention effect UV light alone reduced weevil responses in modeling.
- Intervention effect Yellow and UV light together increased weevil responses at a UV reflectance threshold.
- Association Differences in yellow and UV flower reflectance influenced weevil host selection.
- Observation Weevil attraction differed between S. alba and B. napus odors and among resistant and susceptible accessions.
- Mechanism Variation in 2-phenylethyl glucosinolate was suggested to influence weevil attractiveness.
- Observation Adult weevil feeding and oviposition preferences differed between resistant and susceptible genotypes.
- Observation Weevil oocyte development, larval biomass, and larval development time varied among resistant and susceptible genotypes.
- Mechanism 1-methoxy-3-indolylmethyl glucosinolate was implicated in antixenosis and antibiosis resistance.
- Intervention effect Mixed plots of resistant and susceptible genotypes affected weevil spatial distribution and oviposition.
- Mechanism The mixed-plot results were consistent with associational resistance attributed to lower susceptible-plant apparency and resistant-germplasm antixenosis.
