Shoot tissue eaten 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.
