PREVALENCE OF SUCKING PESTS IN GRAPEVINE AGROCENOSIS

Тhe article presents data on the prevalence of sucking pests ‒ grape thrips, rose leafhopper, buffalo leafhopper during the growing season of grapevine plants in 2021. In recent years, an increase in the number and harmfulness of sucking pests of thrips and leafhoppers has been noted in the Rostov region, which is due to climate change, the weakening of organiza-tional and economic measures and agricultural practices (an increase in the number of waste lands and the spread of weeds on them). The research was carried out in the conditions of the experimental fields of the "Novocherkassk" and "Nizhenekundryuchensky" departments on the varieties Cvetochniy and Cabernet Severny. So, in the conditions of 2021, two generations of grapevine thrips, three generations of roseate cicadas and one generation of ceres-buffalo ci-cadas developed. In the course of monitoring studies, we found that the most widespread populations in the conditions of the vegetation period of 2021 were: the roseate cicada and the ceres-buffalo cicada, which were identified both in the conditions of the experimental field of the Novocherkassk branch (more South – Novocherkassk) so it is in the conditions of the experimental field of the "Nizh-nekundryuchenkso" department (more northern – Ust-Donetsk district). Planning and organiza-tion of plant protection should be based on the forecast of the phytosanitary state of the agro-cenosis, which is based on the monitoring of harmful sucking pests.
