Other claims from this paper (13)
- Observation Accessions of S. sparsipilum and S. wittmackii were significantly more resistant than the other species.
- Observation Resistance in S. multiinterruptum was generally concentrated in the tuber periderm.
- Observation In S. sparsipilum and S. wittmackii resistance was mainly cortex-based.
- Observation Unidentified cortex-resistance factors in all three species reduced larval survival.
- Observation Unidentified cortex-resistance factors increased larval and pupal development times.
- Observation Unidentified cortex-resistance factors had no apparent effect on pupal weights of survivors.
- Observation A high proportion of larvae abandoned or died within tubers of S. wittmackii.
- Intervention effect Resistance in S. multiinterruptum and S. sparsipilum decreased as tubers sprouted.
- Intervention effect Resistance in S. wittmackii was more stable as tubers sprouted.
- Intervention effect Periderm-based resistance was more stable than cortex-based resistance in S. multiinterruptum during sprouting.
- Intervention effect Cortex-based resistance was stable in S. wittmackii as tubers sprouted.
- Intervention effect Resistance may have increased on some older sprouting tubers.
- Recommendation Solanum multiinterruptum and S. sparsipilum are proposed as potential sources of resistance against the potato tuber moth.
