Orosanga japonicus Melichar, 1898 ( Figs 9 and 18a–b )

Recorded damage and economic importance in the orchards of Iran: This is the first record of this species in Iran. It was first collected in the north of the country (Mazandaran province, 7♂, 1♂, and 47 nymphs) in 2010. During 2013, 2015 and 2016 many specimens were collected among large populations on Kiwi fruit and fig in other localities in the north. The large populations of the nymphs and adults along with the damage caused by their direct feeding and anecdotal reports of heavy deposits of “honey dew” on leaves, suggest the potential for economic damage but its pest status remains unknown.

Recorded damage in the orchards of other parts of the world: The species has been recorded on grapevine and fig in Turkey and as an agricultural pest in Ukraine and Georgia ( Demir 2009; Gjonov 2011; Gjonov & Shishinova 2014).

Recorded distribution in Iran: North, along the shores of Caspian Sea.

Conclusion: Given the recent discovery of large populations of the species in the north of Iran and its recorded pest status in adjacent countries, the species may be considered invasive. The economic damage made by the species and the necessity of using control methods need to be investigated urgently.
