The suborder Auchenorrhyncha is a diverse group of sap-feeding insect species, many of them of economic importance. The paper presents comparative results on the ecological characteristics of species communities of Auchenorrhyncha sampled in one apple orchard and one plum orchard that belong to the experimental field Moara Domnească Didactic Station in the year 2022. The insects were collected using dual-sided yellow sticky traps. A number of 9 traps/orchard was used from early April till mid-November (234 traps in total), replaced every two weeks. Altogether, 34 species have been identified, 30 in apple orchard and 32 in plum orchard, totaling 7403 specimens, 6058 (81.8%) in the apple orchard and 1345 (18.2%) in the plum orchard. The most abundant species found in the apple orchard was Empoasca decipiens with 3614 specimens (59.66%), with a constancy of 64.1%. In the plum orchard, two species were the most numerous, Fieberiella florii with 411 specimens (30.6%) and Zygina flammigera with 304 specimens (22.6%), having a constancy in the samples of 24.8 and 29.9% respectively. Adult populations dynamics were performed for relevant species in both orchards.
