Phytoseiulus persimilis

Phytoseiulus Persimilis is a tropical Predatory Mite. Adults are bright reddish orange, with long legs and pear-shaped bodies, 0.5 mm long. Unlike its prey, Persimilis do not spin webbing. Phytoseiulus Persimilis is a predatory might that is similar in size to the two spotted spider might but does not have the black spots and is orange in color.  Persimilis will consume around 5-10 pest adults or up to 20 pest eggs per day. The Persimilis is a very active predatory might and the only time it stops is to feed upon a spider mite.  The Persimilis will tolerate hot temperatures reaching as high as 95 degrees, as long as the humidity is between 60% and 90%. The main difference body feature of the Persimilis and Spider Mites is the Persimilis has a mouth that extends in front of their body while the Spider Mites mouth extends downwards. The Persimilis has the same life cycle stages as the Longpipes and the Californicus mentioned further up the page.Life Cycle Stages: eggs, larvae, protonymph, deutonymph and adults. Persimilis survive very well in either greenhouses or outside applications.Target Pest: Two-Spotted Spider Mite.

A natural way to Spider Mite control!

Due to a high demand, listening to our customers and research, we have developed a mixture of 3 Predatory Mites called “Special Blend”, normally consisting of an assortment of the following; M. longipes, N. californicus and P. persimilis. Special Blend is best used in unknown growing conditions. Our Special Blend takes the guess work out of which mite should be used in your Garden, Green House, or Grow Room. It has been proven to be very effective. You will see a mixture of bright reddish orange, colored mites with obvious long legs. These mites can tolerate temperatures up to 95°F., but do best in temperatures between 60° -85° F. They do well in humidities ranging from 50%-90%. To raise the humidity level you can lightly mist the plants or surrounding walkways. 

Our different Predatory Mite species are also sold separate for known growing conditions. All species are listed in our Spider Mite Control Page.

 

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.

Target Pest Temp & Humidity Release Rates
Two Spotted Spider Mite For optimum performance will be between 70-85°F with a relative humidity of between 60-90% Low: 10-18/yd, tri-wkly, 2-3 times.Med: 18-26/yd, bi-wkly, 2-4 times.High: 26-32/yd, weekly, 3-4 times.

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.
