At different stages of the cycle of providing the agricultural producers with plant protection means, the producers and consumers of beneficial insects and ticks face a number of problems. In particular, during the production and application of the predatory ticks in certain periods a problem exists of inconsistency of the rate of delivery of the finished products to the needs of the end consumer. The impact of storage under conditions of lowered temperature (from 0 ºС to +15 ºС) upon the biological parameters of the predatory tick Amblyseius swirskii: survival, fertility and migration activity was studied. Based on the statistical processing of the results of laboratory research on the PC, it was found that minimisation of the predator losses can be achieved at a storage temperature of +6 ºC. In addition, to ensure the corresponding values of biological indicators, the storage period should not exceed 8 days. The obtained results allow the development of a new storage method for Amblyseius swirskii in order to solve the problem of the mismatch in the rate of supply of predatory ticks to the needs of the end user. The storage of the ticks at low temperatures for a period of more than 8 days during mass dilution for application on the plants is not justified. By introducing the storage of Amblyseus svirsky at low temperatures, the proposed approach allows significant solution of the problem of uncoordinated rate of delivery of the finished products to the non-rhythmic demands of the final consumer.
