Adults
- Adults can be seen feeding on fruitlets during and after blossom and are readily collected by beating.
- Growers should also tap-sample nearby hawthorn and blackthorn hedgerows, to assess the risk of weevil damage.
Damage to fruits during the growing season, at harvest or during grading
- Damage occurs gradually as weevils feed over a period of weeks during and following flowering.
- Fruitlets can be readily inspected for damage.
- If significant fruit puncturing damage to fruits is seen one season, treatment the next season to avoid damage intensifying is likely to be justified.
