Mites belonging to several species were found in the substrate used for cultivation of the oyster mushroom:
* Tyrophagus putrescentiae (Schrank 1781);
* Histiostima feroniarum (Dufor 1839);
* Siteroptes mesembrinae (Canestrini 1861);
* Siteroptes kneeboni (Wicht 1970);
* Arstoseius semiscissus (Berlese 1892);
* Arctoseius cetratus (Sellnick 1940);
* Dendrolaelaps rectus (Karg 1965);
* Dendrolaelaps fallax (Leitner 1949);
* Ameroseius imparasetasus (Westerboer 1963);
* Lasioseius furcisetus (Athias - Henriot 1959). Of mites, Histiostoma feroniarum, Siteroptes kneeboni and S. mesembrinae were the most numerous in the oyster mushroom houses. In some mushroom houses, the copra mites, Tyrophagus putrescentiae, pests of oyster mushroom mycelium, were found in the substrate. All these mites were accompanied by several predatory mites (Dendrolaelaps fallax, D. rectus, Arctoseius semiscissus.
