Stratiolaelaps scimitus target eggs, larvae and pupae of Sciarid flies or Fungus Gnat, preferring smaller larvae. Also effective against other soil-living insects like thrips pupae, Collembola, and nematodes. Also considered to be effectivie against snake mites and other pests found in reptile and arachnid tanks.

Description:
Stratiolaelaps scimitus (formerly Hypoaspis miles) is a soil-dwelling mite capable of the prevention, control, and management of sciarid flies, shore flies, various thrips and other soil pests. STRATIOforce are shipped as adults, immatures and eggs in liter-size shaker bottles or bulk bags/buckets filled with a loose vermiculite carrier and clean peat. In this form, STRATIOforce are very easy to distribute in the crop. STRATIOforce can help prevent thrips from becoming intolerable. They can be instrumental in assisting other predators with the control of fungus gnats and springtails (order Collembola). Currently under investigation is the potential for these mites to impact root mealybugs (Rhizoecus arabicus and other Pseudococcidae family members), sow bugs and pill bugs, also known as rolly-pollies (Portcellio spp. and Armadillidium vulgare, respectively), and also considered to be effectivie against snake mites and other pests found in reptile and arachnid tanks

Life-style:
These robust 0.8 mm. richly-colored tan to brown mites live, eat and reproduce in the soil or soilless medium in containers and planters and, on the walkways and floors of greenhouses. The STRATIOforce females’ eggs hatch into super small larvae which develop into tiny dark brown, almost black, nymphal forms before reaching adulthood. These, too, are fierce predators, consuming many pests, mostly the eggs and smaller larvae (first and second instar) of fungus gnats and the pupal stages of thrips. The life-span of these predators is about 13 days but they reproduce profusely in what little time they have. The conditions for optimum performance will be between 60-72°F, and we’re talking about soil temperatures, with a relative humidity equal to that found in a friable, slightly moist medium, compost or soil. But these are optimum conditions, and not necessarily a prerequisite of successful implementation. Please note, however, considerably cooler temperatures will hamper reproduction.

Benefits:
STRATIOforce are very cost-effective. A little bit goes a long way and they can last such a long time. These predators, like Amblyseius cucumeris, are supplied with some prey mites (Tyrophagus putrescentiae). These prey mites are merely a non-sustainable food source (but only after the contents are distributed, left in the bottle the prey mites will reproduce) for the predatory mites while they’re in transit. These predators are compatible with many insecticides; a real plus in an Integrated Pest Management (IPM) program. Part of the reason for this is simple: these mites are protected in the soil during spraying. They do wander at night, though, so caution is still advisable. This wandering, however, has its advantages: the mites can usually establish themselves in the entire area.

Drawbacks:
You get a lot, but you have to use a lot. Good thing they’re inexpensive. These mites like humid conditions. Therefore, growers of some herbs, most cacti and some succulents may not have suitable soil conditions for these predators. They probably won’t have fungus gnats either. And as far as thrips…? Perhaps (see Advisories).

Scouting:
Using the paper method and/or yellow and blue sticky traps to detect thrips is a sure way to progressively determine your predators’ efficacy. Using yellow sticky traps (lying sticky-side-up at surface level) and potato disks to monitor fungus gnat levels will do the same. Unless your scouting is really top-notch, you’ll probably miss most of the predators present in the soil or medium. But this doesn’t have to be the case. First look at the mites in the container so you may be better able to identify them later. Now, in the release site (this works best in other than small containerized plantings) place stones, small pieces of bark, etc. around the site. Then, during your weekly scouting rounds, you can flip over the “little shelters” to look for your beneficial mites.

Advisories:
For fungus gnat control, 6″ pots and up are probably the best bet for containerized plant applications. If they’re smaller than that, we normally recommend parasitic nematodes. For thrips control, however, it is best to use the mites in nearly every application — but not alone. The thrips’ in-ground stages make up only a small percentage of their overall life-span. This is why H.miles can only handle about 30% of the overall population, and is always used with an above-ground predator. However, let it be known that the impact of STRATIOforce on these extremely pernicious pests is noticeable (at worst is 30%)! Do not rely entirely on the long-term establishment of H.miles. Multiple and regular releases are (as it is for most of our other biocontrols) recommended. One rule-of-thumb to consider: the bigger the container or release site the longer the interval between releases can be (potentially, and thus fewer releases); and the opposite is true for smaller containers or growing areas.

Usages:
Greenhouses/interiors are where these mites are most often used. However, We have heard excellent reports from outdoor nurserymen who have had outstanding results.
