Stratiolaelaps scimitus

Stratiolaelaps scimitus predatory mite


Soil-dwelling mite Stratiolaelaps scimitus (Hypoaspis miles) is a native species, which feeds on thrips (prepupa and pupa), fungus gnats, root scales, root aphids, mealybug crawlers, spidermites in greenhouses, hydroponic and mushroom crops. This product is perfect for an in-depth “cleaning” of the soil before starting the season.

This voracious mites has also been recommanded as a biological alternative for poultry red mite (Dermanyssus gallinae) and for the reptile mites (Ophionyssus spp) in tropical and semi-tropical habitat.

Adults are light brown and less than 1 mm long. They move quickly at the soil’s surface. After mating, female lays eggs in the growing medium. Juvenile are also predators and feed on the small pest they find in the soil.

Sprinkle Stratiolaelaps scimitus directly on the ground. It can live in different types of substrate such as potting soil, coconut fiber, rock wool, etc. In indoor production, this predator is known to establish well in crops planted directly on the ground or in potted plants. Stratiolaelaps scimitus is easy to establish and helps maintain permanent pressure on pests until the cold of winter. A single introduction is generally sufficient at the start of the season.

Compatible with other soil biocontrol agents such as Dalotia (Atheta) coriaria , beneficial nematodes and with entomopathogenic fungus-based bio-insecticides such as BioCeres.
