Phytoseiulus persimilis Athias-Henriot, 1957

Predatory mites, Phytoseiulus persimilis Athias-Henriot, 1957 (Acari: Phytoseiidae) are very small (0.5 mm) arthropods that are considered beneficial. They are known to prey on major arthropod pests in greenhouses, especially other mites, and have a global distribution for the most part due to their use as a biological control agent (predatory action of other mite pests makes them useful). Mites have a unique life cycle compared to many insects as they pass through the egg, nymph and adults stages. The life cycle, depending on conditions, can take three to four weeks.
