Andersoni (Amblyseius andersoni)

Amblyseius andersoni is a predatory mite that feeds on small arthropod prey and pollen. Less than 0.04 in. in length, andersoni mites feed on small arthropod prey and pollen which allows their application before the pest arrival.

Main target pests: Two-spotted spider mite (Tetranychis uriricae) and other mites including European red, broad, cyclamen and russet mites.  Additional targets are Western flower thrips.

Often used in tomatoes due to its ability to maneuver between trichomes. They are active across a wide temperature range, allowing for early season introduction into crops yet might enter diapause with cooler temperatures and short day lengths (<10 hr.).


BioAndersoni is packaged in a bottle containing 50,000 predatory mites.

Also available in bags containing 125,000 predatory mites

BioAndersoni Sachets are available in boxes with 250 sachets (62,500 predatory mites).

Dosage can vary depending on the crop and the level of infestation.


Bottle application:

  • Packaging must be kept intact until placed in the field.
  • Remove the product containers from the box, one at a time.
  • Before use turn, roll the bottle back and forth gently, to mix BioAndersoni with the vermiculite.
  • The predators are released by sprinkling the contents of the bottle on the leaves of the host plants, preferably in a shady area.
  • Do not expose the bottles to direct sunlight.

Sachet application:

  • Hang directly into a well-formed axillary meristem at medium height or where flowering is present.

Suggested application rates:  Sachets: 1 sachet per plant or propagation tray.   Loose: 1 mite per sq ft - higher with infestation

Please note that the frequency and amount to be released is determined by the type of crop, environmental conditions, level of infestation and damage incurred by the pest.
