Leaf rolls 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.
