Diversity of Invasive Auchenorrhyncha Species Detected in Apple and Plum Orchards in Moara Domnească in the 2022-2024 Period

This paper presents data on the presence, abundance and diversity of invasive Auchenorrhyncha species in two orchards, apple and plum, in the experimental field Moara Domnească Didactic Station, Ilfov county (Southern Romania) in the years 2022, 2023 and 2024. The insects were collected on yellow sticky traps, 9 traps/orchard were installed and replaced every two weeks from mid-April until early November. A total of 339 individuals were collected (86.14 % from apple and 13.86% from plum) belonging to seven species, Japananus hyalinus, Scaphoideus titanus, Orientus ishidae, Erasmoneura vulnerata, Stictocephala bisonia (syn. Ceresa bubalus) and Metcalfa pruinosa identified in both orchards, to which Phlogotettix cyclops species is added in apple orchard. Cicadellidae family was the most abundant in both studied orchards, reaching a relative abundance of 93.15% in apple and 80.85% in plum of the total captures. The most abundant species was the Japanese mosaic leafhopper Orientus ishidae (62.67%) in apple and the North American leafhopper Erasmoneura vulnerata (42.55%) in plum orchard. Ecological parameters and indices of similarity, species richness and diversity were calculated and analyzed for each orchard and sampling year.
