Abstract

Strawberry (transparent) tick ( Phytonemus pallidus (Banks) ssp. fragariae (Zimm.) Lindquist) is the most dangerous phytophagous of wild strawberry (Fragaria x ananassa Duch.) in all regions of its cultivation. The vast majority of varieties are badly damaged by Ph. pallidus. In recent years, both the percentage of planted plantations (often reaching 100%) and the degree of damage to plants (up to 3000 moving individuals and eggs on one unfolding triple leaf) have increased significantly, which is associated with non-compliance of phytosanitary requirements in the production of strawberries planting material. The fight against this secretive pest is very difficult, it is practically impossible to eradicate it in the field in fruit-bearing plantations. Obtaining certified planting material is the most effective method of combating this pest. To this end, we have developed an environmentally friendly method, which is available in all conditions of management, to prevent the spread of strawberry mites with planting material. When applied taking into account the bioecological peculiarities of phytophagous development, dynamics and intensity of vegetative growth of the host plant, this method can reach 100% efficiency.
