Fruit boring by leafroller
caterpillars |
Hatching leafroller caterpillars settle mainly on the
lower surfaces of leaves where they feed near the main veins or in
shoot tips. Some settle at the calyx or
stem end of fruit and may cause stings
on the surface. Leaf feeding
and shoot damage often
include leaf folding and rolling.
The fruit surface is eaten and some
caterpillars bore into the fruit, particularly through the calyx.
Faecal pellets (frass) are often found
with damage. Leafroller damage is characterised by silken webbing
on both fruits and foliage, and even bud damage in winter/spring. Shoot distortion is caused by
feeding and the tieing of the young leaves and growing point with
silk.
