As the fruit Slugworm name suggests, this sawfly
larvae pest looks halfway between a slug and a worm - Even leech-like.
It feeds upon the upper surface of leaves from a wide range of fruit
trees and ornamentals, such as apples, pears, plums, Cherries, Crataegus
and Sorbus varieties. Damage normally becomes visible from June until
October (Leaf fall) and is apparent with the lace like skeleton or brown
patches often left behind.
Fruit Slugworms are actually pale yellow, but are
covered with a black slime. Spray with a contact spray such as
Bifenthrin if damage become noticeable - alternatively an organic
fatty Acid spray will do the trick. Repeat applications my be
needed as there can be several generations of Fruit slugworms in a
single season. |
