In this study, the feeding activity of overwintering larvae of A. sabella on wooden texture of young offshoots, varieties Barhi, during winter in December and January 2021, is reported. Due to the feeding activities of larvae under the bark, burrowing into the base of fronds in the lower section of offshoots, the exit of plant sap from the feeding place, presence of larval webs and excrement cause pollution. In the offshoot and samples with a large populations, the activity of two or three simultaneously on crabs, causes weakness and destruction of crabs.
