Other claims from this paper (11)
- Observation Apion curtirostre was the commonest weevil attacking Rumex acetosa near Lancaster.
- Observation Male Rumex acetosa stems appeared earlier and were smaller than female stems.
- Association Taller female stems survived longer than shorter stems.
- Observation Weevil survival was lower in male than female stems.
- Association Stem sex was the primary determinant of oviposition choice and thickness secondary.
- Intervention effect Introduced eggs survived better in Rumex acetosa than in the other Rumex species.
- Observation Weevil survival in female Rumex acetosa was twice male survival.
- Association Egg survival at densities of 4, 8 and 16 per stem was twice that at 32 and 64.
- Association Female stem size decreased as attacking weevil number increased.
- Observation Male stem size showed no significant effect from weevil attack.
- Observation No adverse effect on seed production was detected.
