Strateo Mite (Stratiolaelaps scimitus) is a predatory mite that lives in the soil and feeds on all stages of Fungus Gnats (Sciara spp., Lycoriella spp. and Bradysia spp.), Western Flower Thrips pupae (Frankliniella occidentalis) and Shore Flies (Scatella spp. and Ephydridae spp). They also feed on root aphids such as; Rice Root Aphid (Rhopalosiphum rufiabdominalis).
Strateolaeleps have white eggs (0.35 mm) and their 1st instar larvae is white, has 6 legs, and does not feed. The adult is brown, very small (1 mm long) with 8 legs. Development time varies with available prey species, but is approximately egg to adult on fungus gnat (15 days at 20˚C). Temperatures above 32˚C will stop development.
This predatory mite is compatible with nematodes, such as Steinernema feltiae.
