Powdery mildew (Ascomycotina: Erysiphales) — an alternative food for the predatory mite Typhlodromus pyri Scheuten (Acari: Phytoseiidae)

AbstractThe effectiveness of the predatory mite Typhlodromus pyri and of an application of Polysulphide-Ca was compared during 2006–2008. The experiment showed differences in infestation levels of pear leaves caused by Eriophyes pyri. The highest percentage of leaves with symptoms was found in untreated control group (⊘ 20.9%); the lowest percentage was found in plots treated with T. pyri (⊘ 3.7%); and a slightly higher percentage was found in plots treated with Polysulphide-Ca (⊘ 8.6%). During 2006–2008 the percentage of leaves with symptoms was approximately the same only in the untreated control plots (from 20.3% to 21.5%). The percentage of leaves with characteristic symptoms in plots treated with T. pyri decreased from 5.5% in 2006 to 4.3% in 2007, and to 1.3% in 2008. On the other hand, the percentage of leaves with symptoms in plots treated with Polysulphide-Ca increased from 5.5% in 2006 to 8.5% in 2007, and to 11.8% in 2008. The intensity of symptoms on infested leaves was also different depending on treatments and years. The average biological activity was 82.4% in plots receiving releases of T. pyri and 58.8% in plots treated with Polysulphide-Ca.

The Family

AbstractDuring 2005–2007, 1,332 individuals of predatory mites were found in integrated and ecological orchards in Slovakia. Seven predatory mite species of the family Phytoseiidae, namely Phytoseius echinus, Phytoseiulus macropilis, Euseius finlandicus, Typhlodromus pyri, Paraseiulus triporus, Amblyseius andersoni and Neoseiulella tiliarum, were identified. Out of 1,332 individuals, 519 (39.0%) were found in the apple orchards and 813 (61.0%) in the pear orchards. Out of all predatory mite individuals, 460 (34.5%) were found in the integrated pest management system (IPM) and 872 (65.5%) in the ecological pest management system (EPM). In apple orchards, P. echinus was dominant and constituted 49.3% of the detected mites. In pear orchards, E. finlandicus was dominant and constituted 48.7% of the detected mites. Typhlodromus pyri was also abundant, especially in pear orchards. The other species were less abundant.
