Description

Amblyseius swirskii

Amblyseius swirskii: is a generalist predatory mite that feed on Hemp Russet Mites, Broad Mites, Thrips, Whiteflies, Spider Mites, Tarsonemid Mites, consumes small soft-bodied insect pest species and pollen from the plants. Adults have eight legs and the body is a whole unit, not made up of segments. Their color is completely dependent on what the mites have been eating.

Release Rates: For light to moderate infestations release 8-12/sq.ft., weekly, 3-4 times. 5,000 – 20,000/acre for the first and second week and then 2,000 a week, for weeks 3, 4 and 5. This Predatory Mite does not go into diapause (dormancy) in response to shorter days . This means that swirskii is also active on shorter days (with less than 12 hours of light). The temperature is an important aspect, if the temperature falls below 60 °F the predatory mite will be virtually inactive. Their optimum temperature is between 77-83 °F.

For Best Results

Hanging sachets:
Hang from crop wire or under plant canopy
Do not hang adjacent to heating pipes

Bulk Bottle: 
1 liter containing 25,000 mites
Shake small quantities onto the crop at the base of a plant.

We have found it to be very effective to spread liter containers into solo cups and hang under canopy of plant with hooks

Release Rates

Release rates are highly variable and are based on the severity of the infestation. The first step is to try to get an approximate count on how many mites you have infesting each plant. There are usually hot spots that Spider Mites migrate to, so we recommend looking at those areas to get a rough estimate of how many are in the area. After doing this our rule is one predatory mite for every 5 pests. If releasing them as a preventative measure we recommend 4 mites per sq. ft. of growing canopy. For maximum efficacy bi-weekly releases 2-3 times is needed, or until the predatory mites have dominated the infested area. They work well in gardens and in controlled environments a like.

Release Instructions

  • Keep the package or vial in a cool location until you can release the predators. Ideal storage temperature is 50°F (10°C). But remember to release them as soon as possible.
  • You should be able to see the predatory mites with normal vision. Some may be seen in the cap after it is removed but, the easiest way is to sprinkle some of the corn cob meal on a white paper under a desk lamp or flashlight and watch them run on the paper.
  • Roll or tumble the vial to mix. Mist the leaves with water using a pump-spray bottle.  Remove the cap and sprinkle the contents on the infested areas of the plants.  The meal can be brushed off after an hour or so when the predators have left.  If you do not want the meal on the plants place paper or foil on plant to place material.
  • The predators will go to the underside of the leaf where the pest mites are usually found.
