“…For example, our research established that the main plant reservoirs of potato viruses are perennial weeds such as the field sowthistle Sonchus arvensis and the common dandelion Taraxacum officinale. Plants of Tripleurospermum inodorum infected with PVS suffered from different pathological processes -changes in leaf shape, leaf curl, proliferation, the abscission of flowers and buds, purple leaf axils, the yellowing of abscission of upper leaves, and the general inhibition of plant growth [36]. Our research determined that Trifolium pratense typus L., Chenopodium album L., Plantago major L., Barbarea vulgaris W.T.…”

Solanum tuberosum L. is susceptible to 40 different virus species and 2 viroids. To prevent plant viruses from spreading in field conditions, it is necessary to have reliable data on the species composition of plant reservoirs of viral infection, the total activity of insect vectors, and possible ways of virus transmission in a particular territory of seed material production. Attention should be paid to the factors that facilitate and hinder the disease development in crops and to disease symptoms in different potato varieties. Manifestations of viral infections were monitored on every plant from the sample at the stages of initial growth, bud formation, and flowering and before the removal of potato haulms. Insects were collected using standard entomological method. The total RNA was isolated employing commercial kits for the extraction of nucleic acids from plant material “PhytoSorb” (Syntol Llc) and the benchtop automated extraction instrument KingFisher Flex (ThermoScientific) with magnetic particles. Plant viral infection was observed to accumulate if potato planting material was not renewed. The tested potato plants contained mixed viral infection, which consisted of viruses from mosaic group: PVY, PVX, PVM, PVS PVA, as well as PSTVd and PLRV. Without the renewal of seed potatoes, the concentration of plant viruses in an agroecosystem rises and causes secondary infections in potato plants. The research identified the main insect-vectors in the agroecosystem of potato fields: insects from genera Cicadella, Henosepilachna vigintioctomaculata, Dolycoris baccarum, Mythimna separata, Lygus pratensis, and Rhopalosiphum padi. Many wild weeds serve as fodder plants for insect vectors facilitating the accumulation of plant viruses in agroecosystems. It was established that perennial weeds were the main plant reservoirs of dangerous viral infections, e.g. Sonchus arvensis and Taraxacum officinale. We determined that Trifolium pratense typus L., Chenopodium album L., Plantago major L., Barbarea vulgaris W.T. Aiton, and Ambrosia artemisiifolia L. were the reservoirs of PVY. All these factors can lead to an epiphytotic situation.

“…The four most common herbivore species are known to be vectors or carriers of plant pathogens (viruses, phytoplasmas, bacteria, and fungi) (Table 3). L. pratensis has been identified as a carrier of potato viruses-potato leaf roll virus (PLRV), potato virus Y (PVY), potato virus A (PVA), potato virus S (PVS), and potato virus M (PVM) [77,78]. The recognized vectors for these viruses are aphids.…”

“…PVRL is transmitted in a persistent circulative manner; all the other viruses are non-persistently transmitted and spread through tubers as well as mechanically [82][83][84][85]. A. artemisiifolia serves as a reservoir for the PVY virus [77,78]. L. rugulipennis and A. lineolatus were recently identified as new carriers of Ca.…”

The common ragweed (Ambrosia artemisiifolia Linnaeus 1800) is an exceptionally invasive species. The information on true bugs occurring on ragweed plants is limited in the invasion region. The objective of this study was to determine the species composition of Heteroptera associated with A. artemisiifolia, to assess their vectoring potential based on a literature review, and to compare species similarity in the surveyed fields. Field surveys were conducted in 2020–2021 at 10 sites in southern Slovakia. Sweeping and visual observations were conducted in field margins, weedy agricultural fields, and mowed meadows infested with A. artemisiifolia. In the study, food specialization, the abundance of individual species, and their assignment to families were precisely determined. The Jaccard similarity index was used to evaluate similarities in species composition among the sites studied. A total of 2496 true bugs were recorded, representing 47 species of Heteroptera from 12 families. The most common phytophagous species were Nysius ericae ericae (Schilling, 1829) (Pentatomomorpha, Lygaeidae), Adelphocoris lineolatus (Goeze, 1778), Lygus rugulipennis (Poppius, 1911), Lygus pratensis (Linnaeus, 1758) (Cimicomorpha, Miridae), and a zoophagous species Nabis (Dolichonabis) limbatus (Dahlbom, 1851) (Cimicomorpha, Nabidae). The species similarities in pair-wise combined localities were low, with a dominance of highly migratory and polyphagous species able to traverse the field from the adjacent landscape. A. artemisiifolia is a known host for plant viruses and phytoplasmas, and several Heteroptera species are carriers of these plant pathogens. Halyomorpha halys was the only detected vector of phytoplasmas, and its abundance on A. artemisiifolia was extremely low.

Scientific relevance. Plant viruses cause a significant economic loss to potato production, especially if plants are infected at early growth stages and infections are mixed. Viral diseases reduce both yield and quality of harvested crops. Detection and identification of plant viruses are key important to prevent their spreading and to achieve potential yield predetermined by characteristics of varieties.Research methods. Seven potato varieties, bred in Russia and overseas, were used in the field experiment: Smak, Avgustin, Yantar, Laperla, Labella, Red Lady, Sante, Belmonda. Viral infection rate was measured by the percent of plants with symptoms to the total number of plants. In addition to infection frequency, a disease rate was described after visual estimation. Total RNA was isolated from the collected leaves according to Bekesiova I. et al. 1999 [13]. Qualitative and quantitative estimation of plant viruses in the samples were conducted by single-step real-time RT-PCR with fluorescent detection with the Applied Biosystems QuantStudio 5 and commercial kits “Potato Virus X, Y, M, L, S, A, PSTVd-RT” (Syntol Company) according to the official protocol of the kits.Results. As a result of our research, symptoms of mixed viral infection were described for potato varieties depending on concentrations and proportions of these viruses in a plant. Mixed viral infection in the potato field in Primorsky Krai comprised PVY, PVX, PVA, PVS, PVM, also PLRV and PSTVd.
