Abstract

In August 2021, a bug species was observed causing damage to commercial thornless blackberry plants in Rasht County, Guilan Province, Iran. This insect was identified as belonging to the family Coreidae (Hemiptera: Heteroptera). After thorough examination and comparison with specimens from the insect collection at the Natural History Museum of the University of Guilan, it was confirmed to be Coreus marginatus marginatus (Linnaeus, 1758). The insects fed gregariously on ripe blackberry fruits, resulting in crushing and maceration, which ultimately led to the desiccation of the fruit. This is the first documented instance of damage caused by this species on thornless blackberry in Iran.
