Predatory mites (Acarida: Phytoseiidae) are one of the most important natural enemies of spider mites. The main factor, limiting their occurrence during the vegetation season, is an irrational pesticide treatment. The results of field and laboratory research showed that Amblyseius andersoni (Chant) is able to fast and effectively reduce spider mites as well as to maintain pest’s population on a low level. Due to their characteristics predatory mites can be used as an effective biological control agent. Laboratory tests were conducted to determine the selectivity to the predatory mite A. andersoni of the pesticides Mospilan 20 SP, Mythos 300 SC and Ortus 05 SC, commonly used in protection of strawberry plantations. All tested pesticides showed extremely low selectivity, causing a high mortality of predatory mites during the period of 48 hours after the treatment. Thus, there is a need for developing studies on pesticide used in strawberry plantation protection and their selectivity to predatory mites.

Experiments involving the predatory mite Amblyseius andersoni Chant were carried out in the 2009 growing season from May to September. A. andersoni as a species chosen to detailed plot studies was selected on the basis of 2007–2008 observations conducted on strawberry commercial plantations. The model plants used in the study were: strawberry (Fragaria x ananassa Duchesne) cv. Honeoye and herb bennet (Geum urbanum L.). The aim of this experiment was to evaluate the biological efficiency of A. andersoni, as a predator of two-spotted spider mite (Tetranychus urticae Koch) using the dispersion model. On plants surrounding plantations were found eleven species from the family Phytoseiidae, and three were of them dominant species: N. reductus, A. andersoni, E. finlandicus and together they accounted for more than 70%. The plot studies showed that A. andersoni was an effective native predatory mite of the two-spotted spider mite on strawberries plants.
