Target Pests 
Formerly Hypoaspis miles,  a soil dwelling generalist mite that feeds on fungus gnat larvae, pupating thrip, immature root aphids, and small insects. Used as a preventative, this soil mite will help to protect your rooting system from many common pests.  

Applications of Stratiolaelaps soil mites together with Dalotia rove beetles are an effective combination to prevent against root aphids.

Effective use in Commercial Cannabis cultivation:

Rates with Stratiolaelaps in Cannabis seem to vary a little from what the traditional registered rates listed below. We say that because the dollar value of the Cannabis crop is so high. Instead of treating in meters and as a row crop, we recommend that each plant have direct attention to them for optimal results. The climate fluctuation, temperature and humidity changes, the rapid plant growth with new plant growth, not to mention the air movements, and hairiness make Cannabis a beast for treatment.

For Best Results


Fungus gnat prevention in cannabis is a little different as growers are continually transplanting new clones or are transplanting to larger containers. New soil may mean new pests being introduced in your garden. 

Do not mix predators into the growth media before potting plants because they do not survive. Apply Stratiolaelaps shortly within the first few weeks of planting and before fungus gnat levels reach more than 20 adults per trap, per week. To control high numbers of fungus gnats, use of Stratiolaelaps can be integrated with insect parasitic nematodes, which control the larval stage of fungus gnats. 

Do not water soil or growing medium 10 minutes before and a few hours after release. To release, rotate the canister (to distribute mites inside), then open the lid and remove the filter paper. Place the lid back on, and tap the mites out of the canister evenly onto the soil. Also distribute on floors, greenhouse weeds, under benches, and places where fungus gnat larvae will develop. Leave the canister and filter paper in the treatment area to ensure release of all mites. Release product within 1 week of being received. Store canister on its side at 60-70° F.

Please apply Stratiolaelaps within the first week of planting for optimal results.

 

Traditional Horticulture recommendations:

Description

Stratiolaelaps scimitus is a native species of soil-dwelling mite, which feeds on small insects and mites (e.g. springtails, root mealybug crawlers, and spider mites). Adults are tan in color, less than 1 mm long (1/20th in.) and move rapidly over the soil surface. They live, eat, and reproduce in the soil medium and walkways on the greenhouse floor.

Use in Biological Control
This product has been the cornerstone of the industry for over 25 years, where it has been known as Hypoaspis miles. It is an accomplished generalist soil predatory mite, capable of controlling Fungus Gnat larvae, thrips pupae, pathogenic nematodes, Spring Tails, Black Vine Root Weevil, Strawberry Root Weevil, and Cactus Root Weevil to name a few. Though not listed, Stratiolaelaps scimitus being a generalist may help with root aphid prevention also.

Stratiolaelaps are used primarily to control young larvae of fungus gnats in the soil or planting media. They also help control soil stages of thrips and may account for up to 30% of thrips control. They do not control shore flies or moth flies, but will feed on other soil organisms, such as springtails and root mealybugs. They have been used successfully in bedding and potted plant production, seedling and cutting propagation, and poinsettia stock. Stratiolaelaps adapt well to the various growth media and capillary mats used in plant production, but do not survive freezing or flooding conditions.

Life Cycle 
The complete life cycle takes about 18 days at 68°F. The sex ratio is an equal 1:1, females to males. Eggs hatch in 2-3 days into young nymphs, which are also fierce predators that consume eggs and small larvae. Each adult Stratiolaelaps will consume 1-5 prey per day. It can also survive as a scavenger in the absence of pests, feeding on algae and plant debris. Populations will naturally fluctuate throughout the growing season.

Introduction Rates
Apply 25,000 each per 1,000 - 2,000 square feet

Stratiolaelaps is most effective when applied before fungus gnat populations become established or when numbers are still low (below 10 per trap, per week). Two applications of Stratiolaelaps per crop cycle are usually sufficient if used early in the season. The second application should be made 2-3 weeks after the first.

Do not water soil or growing medium 10 minutes before and a few hours after release. To release, rotate the canister (to distribute mites inside), then open the lid and remove the filter paper. Place the lid back on, and tap the mites out of the canister evenly onto the soil. Also distribute on floors, greenhouse weeds, under benches, and places where fungus gnat larvae will develop. Leave the canister and filter paper in the treatment area to ensure release of all mites. Release product within 1 week of being received. Store canister on its side at 60-70° F.
