Quarantine Pests of Tree Crops in the Volgograd Region

The article examines the ecological and biological characteristics of the development and impact of several quarantine organisms, including the emerald ash borer (Agrilus planipennis Fairmaire), the Eastern fruit moth (Grapholita molesta Busck), the California red scale (Quadraspidiotus perniciosus Comstock), and the black pine sawyer beetle (Monochamus galloprovincialis Ol.). It identifies quarantine phytosanitary zones within the Volgograd region and presents a list of measures for localizing outbreaks of these quarantine organisms and/or eradicating quarantine organisms’ populations. Additionally, the article outlines the criteria for confirming the eradication of pest outbreaks and discusses the rationale for lifting quarantine phytosanitary zones and discontinuing the quarantine phytosanitary regime.
