First record from Italy of the Japanese grape leafhopper Arboridia kakogawana

The Eastern Palearctic typhlocybine leafhopper Arboridia kakogawana , feeding on Vitaceae, is recorded for the first time in Italy. In May 2024, adults were detected on yellow sticky traps in three vineyards ( Vitis vinifera ) in Grugliasco, Chieri and Montalto Dora, province of Turin (Piedmont region). This species, through its trophic activity, causes chlorosis on vine leaves that produce negative effects on the maturation of grapes. However, there are no reports that these insects can transmit phytoplasmas or other pathogens affecting Vitis . The male genital characters useful for its identification are depicted, together with those, for comparison, of Arboridia adanae , the other ampelophagous Arboridia species occurring in Italy.
