The species of the Auchenorrhyncha group represent one of the most important risks for apple and plum orchards, some of them being the vectors of major pathogens such as phytoplasmas. This paper presents results on the presence and structure of species of the Auchenorrhyncha suborder recorded in two unmanaged orchards of apple and plum from the northern part of Bucharest (Băneasa area) in 2020. The insects were collected on yellow double-sticky traps (two traps / orchard) placed in the canopy of apple and plum trees and replaced every week from early April until late November. In total, 25 species have been identified in both orchards, accounting 4834 individuals (4036 in the apple orchard and 798 in the plum orchard). In apple, the most abundant species were Orientus ishidae with 3096 specimens (76.7%), followed by Erasmoneura vulnerata with 380 specimens (9.41%), Zygina flammigera with 177 specimens (4.38%) and Anoplotettix fuscovenosus with 156 specimens (3.86%). The most numerically relevant species in the plum orchard were Zygina flammigera with 371 specimens (46.49%), Erasmoneura vulnerata with 115 specimens (14.41%), Orientus ishidae with 106 specimens (13.28%) and Fieberiella florii with 91 specimens (11.4%). Dynamics of adult populations was performed for the most abundant species in both fruit orchards.
