Stratiolaelaps scimitus (Hypoaspis miles) Fungus Gnat Predator
This tiny, translucent brown to tan predatory mite naturally inhabits the top layer of soil where pest insect larvae and pupae dwell. Stratiolaelaps scimitus (Hypoaspis miles) is primarily used for treating and controlling fungus gnat infestations, but can also be released as a control measure for root aphids, spider mites and thrips. Female S. scimitus predatory mites lay their eggs in soil where the nymphs and adults feed on pests. Nymphal feeding focuses on eggs and immature larvae (instars) of fungus gnats in addition to pupal stages of thrips. If the infestation being treated is severe, use S. scimitus along with Sf Beneficial Nematodes and Blue Sticky Traps. Consider using S. scimitus along with Neoseiulus cucumeris if you are treating an active thrips infestation.
Life Cycle & Optimal Conditions for Release:
The S. scimitus life cycle lasts around 13 days and can accelerate or lengthen in different environmental conditions. Optimal conditions for S. scimitus performance are temperatures from 60-74° and high relative humidity. These conditions refer to soil conditions more so than atmospheric conditions as the Stratiolaelaps are most active in the growing medium. Cooler temperatures can have a negative impact on reproduction and development.
Release rates: Some crops benefit when higher release rates are used preventatively.
|Type of Application||Release Rate|
|General Releases||5,000-10,000 S. scimitus per 1,000 ft2 depending on level of infestation.|
|Large Area Releases||25,000-50,000 S. scimitus per acre depending on level of infestation.|
Weekly applications are recommended until infestations subside.
Stratiolaelaps scimitus controls for: Bean Thrips (Caliothrips fasciatus), Fungus Gnats (Bradysia impatiens), Root Aphids, Spider Mites, Springtails, and Thrips (Franklinothrips spp).
General Application Recommendations:
Incorporate mites into growing media at potting or sprinkle onto growing media surface. Rotate tube several times before opening to mix contents. To open lid, push the cut-out on the lid where marked. Rotate lid cover to fully open position for application. Shake tube lightly and tap contents out gently to dispense mixture onto the surface of growing media; S. scimitus will quickly distribute through crop.
