The genus Grapholita Treitschke, 1829 is a complex group belonging to the tribe Grapholitini of the subfamiliy Olethreutinae, due to their similar characteristics among the species. The genus comprises about 150 described species worldwide. The majority of described species occur in the Holarctic region. To date, eight species of Grapholita have been reported from Korea. The genus contains several notorious pests such as G. dimorpha Komai and G. molesta (Busck). Among them, G. inopinata has been doubtful in distribution. This study aim to optimize species specific sex pheromone composition/amount and establish the distribution of the pest species of the genus Grapholita in Korea.
