| Summary: | The main field of research carried out in the Polar-Alpine botanical garden-institute is the plant introduction and acclimatization. The problem of particular complexity is the protection of plant introducents from pests. The representatives of the Coccinea suborder are found in the Far North exclusively in greenhouses. Monitoring of a phytosanitary condition of Polar-Alpine Botanical Garden plant collection fund revealed the most stable pest species in relation to local conditions and methods used to fight against species of the Coccinea suborder. Сomposition of forage plants is defined and species of plant-reserves, on which pest population is formed, are selected. List of tropical and subtropical plants populated by Coccinea in the collection of the Polar-Alpine Botanical Garden is compiled (data on the years of 2004-2013 )
