Other claims from this paper (8)
- Observation Delmarvel, Idea, Lester, Primetime and Seneca strawberry cultivars are not preferred by vine weevil adults.
- Observation Eight of the 21 strawberry cultivars have deterrent leaf hairs.
- Observation Some highly preferred cultivars, Latestar and Tristar, have deterrent leaf hairs.
- Observation Four of the five nonpreferred cultivars lack significantly deterrent leaf hairs.
- Observation The 21 tested strawberry cultivars do not differ in their suitability for vine weevil larval development.
- Mechanism Differences in cultivar susceptibility to vine weevil in the field may involve interactions between palatability and nutritional value of foliage and larval tolerance set by root biomass.
- Observation The nonpreference traits in the foliage of commercial strawberry cultivars are present by chance.
- Recommendation Further selective breeding to enhance strawberry varietal tolerance to vine weevils may be possible.
