Plants and products of plant origin are subject to phytosanitary control during export. This measure is necessary to confirm that the product meets the quarantine phytosanitary requirements of the importing country. This fully applies to the supply of Russian grain abroad, the volumes of which have sharply increased recently. The authors analyzed quarantine lists and requirements of 53 countries in relation to Caryophyllaceae family plants. The grain samples contamination received by plant quarantine laboratories in 2016–2020 was studied. Representatives of Caryophyllaceae family are regularly detected in Russian agricultural products: wheat, barley, oats, buckwheat, rapeseed, sunflower, camelina, mustard, lentils, peas, soybeans, coriander, flax, fodder and lawn grass. The volume of grain exports for 2017–2020 is presented to evaluate possible risks. Thus, more than 20 million tons of regulated export products per year are subject to research.

The spread of Caryophyllaceae weeds in the Russian Federation is shown. These plants are endemic species of Russian flora, which are ubiquitous, widespread or locally spread throughout the country. For each species, original maps of spread were compiled, on the basis of which free areas were identified. It was found that among Caryophyllaceae weeds present in Russia, seeds Silene vulgaris, Silene alba, Agrostemma githago, Stellaria media, Silene dichotoma, Silene noctiflora, Silene nutans, Spergula arvensis, Cerastium arvense are found in the products. The obtained data will be in demand in the field of phytosanitary.

Chrysanthemum stem necrosis virus (CSNV), common in South Korea, Brazil, Iran and Japan, with a strong infection causes the death of host plants, the main of which are Dendranthema x grandiflorum and tomato. Effective vectors of the virus are western flower thrips and tomato thrips. There is a real risk of introduction and massive adaptation of this virus both in green – houses and open ground in the southern regions of the Russian Federation, which accounts for the necessity of its reliable diagnosis by laboratory methods. FGBU “VNIIKR” has experimentally proved that the method of polymerase chain reaction in real time (RT-PCR) turned out to be a more sensitive method compared to classical PCR. Chrysanthemum stem necrosis virus was not detected in chrysanthemum plant samples from several greenhouse farms analyzed by PCR.

The aim of the work was to form a list of pests associated with regulated products – Cucurbitaceae seeds, as well as systematize and categorize it. The data on the turnover of products were analyzed and information was collected, on the basis of which a list of pests related to Cucurbitaceae was created. 144 phytopathogens were analyzed, including 60 representatives of fungi and chromist, 24 bacteria and phytoplasmas, 60 viruses and viroids. It has been established that 23 pest species are directly associated with the Cucurbitaceae seeds – 13 fungi species, 4 bacteria species and 6 virus species. Based on the phytosanitary status and geographic distribution, 3 pest categories associated with Cucurbitaceae have been identified. The first category includes regulated species of quarantine importance for the Russian Federation – 1 bacterium and 2 viruses. The second category includes the pest species present in the Russian Federation that are not regulated by the Common List of Quarantine Objects of the EAEU – 11 fungi species, 3 bacteria species and 1 virus. In the third – the pest species absent in the Russian Federation that are not regulated by the Common List of Quarantine Objects of the EAEU – 2 fungi species and 3 viruses. Category formation of species non-regulated and not widespread in the Russian Federation is the result of one of the stages of pest risk analysis associated with the regulated products under study, and the species included in the category are subject to careful study for the need to be controlled. Thus, the formation of a list of phytopathogens transmitted by Cucurbitaceae seeds, its systematization and categorization were carried out.

The article provides the results of a 2-year (2019–2020) study of entomofauna of the main forest tree pests con­ducted by the authors in the forests of several districts of Irkutsk Oblast. The main aim was to collect entomo­logical material at all stages of development for the for­mation of an entomological collection, mainly insects damaging coniferous trees. There were detected: Si­berian conifer silk moth Dendrolimus sibiricus Tschet­verikov, 1908 in Kachugsky, Bayandayevsky, Slyudyan­sky, Shelekhovsky, Irkutsky, Olkhonsky Districts, gypsy moth Lymantria dispar (Linnaeus, 1758) in Olkhonsky District. All the districts of the study contained pine sawyer beetles of the genus Monochamus Dejean, 1821; totally, 5 species were detected: small white-marmorat­ed longhorn beetle Monochamus sutor (Linnaeus, 1758), white mottled sawyer Monochamus urussovi (Fischer, 1806), black pine sawyer beetle Monochamus gallopro­vincialis (Olivier, 1795), Siberian speckled sawyer Mono­chamus impluviatus Motschulsky, 1859 and Monochamus saltuarius Gebler, 1830. In the forest of the Slyudyan­sky District, a quarantine pest – Japanese silver-fir bark beetle Polygraphus proximus Blandford, 1894, was detected under the bark of Siberian fir (Abies sibirica Ledeb.). On Scotch pine (Pinus sylvestris L.) and Siberi­an larch (Larix sibirica Ledeb.), there was reported mas­sive colonization of six-toothed bark beetle Ips sexden­tatus (Boerner, 1776), larch bark beetle Ips subelongatus (Motschulsky, 1860), on Siberian spruce (Picea obovata Ledeb.) – eight-toothed spruce bark beetle Ips typogra­phus (Linnaeus, 1758).

The article provides the data obtained as a result of testing a synthetic pheromone produced by the All-Russian Plant Quarantine Center (FGBU “VNIIKR”) for monitoring and collecting a quarantine pest – brown marmorated stink bug Halyomorpha halys (Stål). Field screening of the brown marmorated stink bug was carried out on the territory of two countries where the pest is not regulated: the Republic of Hun­gary and the Republic of Abkhazia. To test pheromone traps, a synthetic mixture was used, developed ac­cording to an optimized method, which includes the synthesis of two main components: stereoisomers of 10,11-epoxy-1-bisabolene-3-ol, where racemic citro­nellal was used as the initial reagent, and synergistic substances – methyl-(E, E, Z)-2,4,6-decatrienoate. The mixture was applied to bromobutyl rubber dispensers in a 1 : 1 ratio for each component, respectively, in dif­ferent dosages: 12, 24 and 48 mg/dispenser. As an ad­ditional option, a dispenser made of cellulose in buflen with 48 mg of a pheromone was used. Field test results have shown high attractiveness and species-specifici­ty of 24 mg pheromone applied to a bromobutyl rub­ber dispenser for Halyomorpha halys nymphs. Whereas the 48 mg dosage used with the same type of dispenser was more attractive to the imagoes. Thus, the optimized method for the pheromone synthesis has demonstrat­ed its effectiveness in capturing nymphs and imagoes of the brown marmorated stink bug in both moderate continental and subtropical climates. To clarify the most effective dosage of the synthetic pheromone of the brown marmorated stink bug, further research is needed.
