Abstract

During the 2005–2007, we identified six species of predatory mites in the integrated and an ecological orchard: <I>Phytoseius echinus</I>, <I>Phytoseius macropilis</I>, <I>Euseius finlandicus</I>, <I>Typhlodromus pyri</I>, <I>Paraseiulus triporus</I> and <I>Amblyseius andersoni</I>. The species <I>Phytoseius echinus</I>, <I>Euseius finlandicus</I> and <I>Typhlodromus pyri</I> occurred in both orchards. <I>Phytoseius echinus</I> was dominant especially in the ecological orchard, where its abundance was almost 60% of the overall number of detected mites. The number of all predatory mites differed considerably in the orchards; there was a higher abundance in the ecological orchard. <I>Euseius finlandicus</I> abundance was 38.32% in the integrated orchard and almost 17.61% in the ecological orchard. <I>Typhlodromus pyri</I> abundance was 17.96% in the integrated orchard and 13.63% in the ecological orchard. <I>Paraseiulus triporus</I>, <I>Amblyseius andersoni</I> and <I>Phytoseius macropilis</I> were less abundant.
