TL;DR: It is concluded that, compared to releases with P. persimilis alone, there is no advantage to releasing N. californicus, either alone or in combination with P., and that there was no significant adverse effect of the presence of N.CalifORNicus on the densities of P. Persimilis.

TL;DR: Predatory mites provided an effective control 15-20 days after release, and no additional release was needed during the rest of the growing season, however, when T. cinnabarinus populations were high early in the season, control by P. persimilis proved ineffective.
Abstract: The potential of the predatory mite Phytoseiulus persimilis (Acarina: Phytoseiidae) to control the carmine spider mite Tetranychus cinnabarinus (Acarina: Tetranychidae) on strawberries (cv. ´Camarosa`) grown under plastic tunnels was investigated in 2 fields during the 2001 and 2002 growing seasons in Aydin, Turkey. Three study plots, grower's practice, chemical control and biological control, were established. The population of T. cinnabarinus was controlled in the grower's practice plots by using 1 or 2 acaricide applications. However, it was suppressed with only 1 acaricide application in the chemical control plots at a population level below economic threshold levels. When the pest population level reached 2-3 individuals per leaflet in the biological control plots, P. persimilis was released once at the rate of 1 predator to 20 prey. Predatory mites provided an effective control 15-20 days after release, and no additional release was needed during the rest of the growing season. However, when T. cinnabarinus populations were high (11 mites per leaflet) early in the season, control by P. persimilis proved ineffective. In addition, no significant difference was found in strawberry yields among the 3 treatments, either in terms of fields or years.

TL;DR: Two species Neoseiulus marginatus (Wainstein) and Transeius wainsteini (Gomelauri), which are new records from Turkey, as well as Transeia herbarius (Wainestein) are redescribed.
Abstract: A checklist and a key are given for the 62 species of Phytoseiidae of Turkey. Two species Neoseiulus marginatus (Wainstein) and Transeius wainsteini (Gomelauri), which are new records from Turkey, as well as Transeius herbarius (Wainstein) are redescribed. Amblyseius enab El-Badry, Amblyseius rusticana Athias-Henriot, Typhlodromus tenuis Westerboer, and Typhlodromus intercalaris Livshitz and Kuznetsov are recognized as suspected junior synonyms of Amblyseius swirskii Athias-Henriot, Amblyseiella setosa Muma, T. herbarius (Wainstein), and Typhlodromus (Anthoseius) invectus Chant, respectively. We accept a previous conclusion on the species concept of Phytoseius plumifer (Canestrini and Fanzago) and consider removing Phytoseius finitimus Ribaga from synonymy with P. plumifer.

TL;DR: It is shown that M. brunneum V275 application with the releases of predatory mite have the potential to suppress T. urticae, and the number of new generation mobile stages increased 3–9-fold compared with the initial number of released predatory mites.

TL;DR: Mites preyed more on nematodes in sandy soil than in loamy soil, and it was observed that the mites consumed more S. feltiae IJs than Heterorhabditis bacteriophora (Rhabditida: HeterOrhabditidae).
Abstract: Predation of the entomopathogenic nematode, Steinernema feltiae (Rhabditida: Steinernematidae), by Sancassania sp. (Acari: Acaridae) isolated from field-collected scarab larvae was examined under laboratory conditions. Adult female mites consumed more than 80% of the infective juvenile (IJ) stage of S. feltiae within 24 h. When S. feltiae IJs were exposed to the mites for 24 h and then exposed to Galleria mellonella (Lepidoptera: Pyralidae) larvae, the number of nematodes penetrating into the larvae was significantly lower compared to S. feltiae IJs that were not exposed to mites (control). Soil type significantly affected the predation rate of IJs by the mites. Mites preyed more on nematodes in sandy soil than in loamy soil. We also observed that the mites consumed more S. feltiae IJs than Heterorhabditis bacteriophora (Rhabditida: Heterorhabditidae). No phoretic relationship was observed between mites and nematodes and the nematodes did not infect the mites.
