Other claims from this paper (10)
- Observation Holly trees had stable mean leaf-miner densities but different individual infestation rates.
- Mechanism Holly infestation differences among trees reflected host selection, partly explained by variety and leaf availability.
- Observation Eggs were aggregated on medium to highly infested host trees.
- Observation Mean P. ilicis survival remained below 10%.
- Association P. ilicis survival did not relate to host choice.
- Association Pre-mine mortality was strongly density dependent, probably because of competition in the leaf midrib.
- Observation Most leaves formed a single mine.
- Observation Mine density had a weak density-dependent relation with miscellaneous larval death.
- Association Mine density had a weak density-dependent relation with Chrysocaris gemma attack rates.
- Mechanism Egg distribution determined density-dependent competition in the leaf midrib.
