Environmental conditions
The predatory mite Amblyseius swirskii is:

  • Not susceptible to diapause, so can be introduced in winter
  • Tolerant to high temperature
  • A. swirskii population starts to develop when daytemperature regularly exceeds 20-22°C

Storage and handling
Biological beneficials have a very short life expectancy and therefore need to be introduced into the crop as soon as possible after receipt. Storing them for a period can have a negative impact on their quality and is only possible under the conditions described below. Koppert B.V. is not liable for any loss of quality if the product is stored for longer than recommended and/or under incorrect conditions.

  • Storage after receipt: 1-2 days
  • Storage temperature: 10-15°C/50-60°F
  • In the dark
  • Provide ventilation to prevent CO2 accumulation


  • Amblyseius swirskii can also develop on pollen of sweet pepper and aubergine
  • Apply preventive introduction on pollen only from the moment when crop flowers continuously


  • Mobile stages: beige-pink, droplet shaped, 'pushed down' position on short legs
  • Eggs: oblong, transparant white

All stages can be found in the corner of main vein and lateral veins and in the flowers.

It is not possible to distinguish Amblyseius swirskii in the field from Neoseiulus cucumeris and Amblyseius californicus.

Mode of action
Adult predatory mites search for their prey or wait for it to pass by, then suck it dry.

The introduction rates of this product should be adjusted to the mode of action of the product and the results that can be expected in the crop where the product is applied. Your local Koppert consultant or recognized distributor will be able to advise you further.

Only use products that are permitted in your country/state and crop. Check local registration requirements.
