Issues of biological and food security of the Russian Federation are associated with the invasive processes of pests. Plant quarantine plays an essential role in this direction, in which accurate and operational diagnostics are ensured. An essential aspect of timely detection of alien pests is predicting their potential spread. Reliable prediction of zones of the possible species acclimatization combined with data on possible pathways of distribution ensures early detection of the species in case of its introduction. In the present work, studies were conducted in the context of a phytosanitary diagnosis of three species of hemipterans (Insecta: Hemiptera) that pose a phytosanitary risk for the Russian Federation territory: Chionaspis pinifoliae (Fitch, 1856), Lycorma delicatula (White, 1845), Megacopta cribraria (Fabricius, 1798). Various preparation and microscopy methods were used to study the diagnostic signs of the above pest species and computer methods of habitat modeling. As a result of this research, approaches to morphometric studies of diagnostic signs of pygidium of the Chionaspis pinifoliae-heterophyllae complex for differentiation of Chionaspis pinifoliae and for the formalization of the measurement procedure, which is essential for the practice of phytosanitary laboratories; it is shown that Lycorma delicatula is well-differentiated from other species of the genus, while identification at the level of supraspecific taxa seems complicated and requires appropriate research; the results of modeling the Megacopta cribraria area for Russia showed a high probability of its distribution within the south of Krasnodar Krai and the Republic of Adygea, which should be considered when conducting surveys to identify this pest in case of its possible infestation. Reference specimens of the following species were isolated: Chionaspis pinifoliae deposited in the Zoological Institute of the Russian Academy of Sciences (St. Petersburg) and Lycorma delicatula from the collection of the Zoomuseum of Moscow State University (Moscow). The latter is of practical importance for developing and applying diagnostic protocols in plant quarantine.
