Enhance your pest management strategy with Hypoaspis (Stratiolaelaps scimitus, formerly Hypoaspis miles), a highly effective soil-dwelling predatory mite. These mites are robust predators, supplied in 1L tubes containing 20,000 individuals across all life stages, and are instrumental in controlling a range of small soil-borne pests including fungus gnats, thrips, and shore flies.

Direct Shipping for Maximum Effectiveness: Our Hypoaspis mites are shipped directly from the supplier to ensure they arrive in the best condition to provide effective pest control right away.

Description and Biology

Hypoaspis mites grow to about 1 mm in length, with adults appearing brown and juveniles pale or clear. They thrive by feeding on a wide array of soft-bodied organisms, particularly targeting the egg and larval stages of pests. These mites are exceptionally well-suited for greenhouses and nurseries, areas typically plagued by fungus gnats. They complete their lifecycle from egg to adult in less than 2 weeks at 25°C and can survive long periods on alternative food sources like algae and plant debris when prey is scarce.

Target Pests and Advantages

Hypoaspis mites are specially effective against:

  • Fungus gnats
  • Shore flies
  • Thrips

Advantages include:

  • Longevity and persistence even at low prey densities
  • Suitability for preventative releases
  • Robust nature allowing rapid establishment and distribution in various crop environments

Suitable Crop Environments

These mites adapt to a variety of growing media including soil, potting mixes, and hydroponic bases like coconut coir and rock wool, making them ideal for both greenhouse and field crop environments. They perform best in temperatures of 20-30°C and can remain active down to 10°C.

Recommended Release Rates

For effective pest management, release rates vary:

  • Greenhouse crops: 50 mites/m2
  • Bedding plants: 100 mites/m2
  • Seedlings/cuttings at propagation: 500 mites/m2
  • 150 mm pots: 50 mites per pot

Multiple releases are recommended to ensure continuous control and to foster overlapping generations.

Release Timing and Method

It's best to introduce Hypoaspis preventatively or at the first sign of pest activity. Mites are distributed by sprinkling directly onto the surface of the growing medium or across the greenhouse floor to intercept fungus gnats breeding in soil.

Monitoring and Additional Treatments

After release, monitoring with yellow sticky traps helps track adult fungus gnat populations. Hypoaspis mites, while difficult to spot, significantly reduce the presence of these pests. For higher infestations, consider integrating with other biological controls like parasitic nematodes or Bacillus thuringiensis subspecies.

Storage and Handling

Upon delivery, apply Hypoaspis immediately or store them at 10-18°C for up to 3 days. Handle carefully to ensure the mites are active and ready to establish upon release.

Chemical Sensitivity

While Hypoaspis are more tolerant of pesticides than many predators, some common chemicals can still be detrimental. Always check the history of chemical applications and avoid treatments that could impact mite efficacy.

Incorporate Hypoaspis into your integrated pest management (IPM) plan to effectively control soil-borne pests, maintaining the health and productivity of your crops with a natural and sustainable approach.
