Predatory Mite, Amblyseius swirskii

Product Options

Product Details

Predatory Mite, Amblyseius swirskii is an excellent biological control agent and has been used in controlling tiny pests such as whiteflies, thrips and spider mites that cause a serious damage to many economically important crops grown both in the greenhouses and fields.

Facts (show all)

- Effective against the following pests
  • Asian Citrus Psyllid, Diaphorina citri
  • Broad mites, Polyphagotarsonemus latus
  • Chilli thrips, Scirtothrips dorsalis
  • Greenhouse whitefly, Trialeurodes vaporariorum
  • Tobacco whitefly, Bemisia tabaci
  • Western flower thrips, Frankliniella occidentalis
  • Tomato russet mite, Aculops lycopersici
  • Twospotted spider mite, Tetranychus urticae
+ Key factors for Predatory Mite, Amblyseius swirskii effectiveness
  • Amblyseius swirskii are natural predators of insect pests.
  • Amblyseius swirskii are considered as the warm adapted predatory mites because the optimum temperature required for their normal reproduction and development is between 20°C (68°F) and 29°C (84.2°F).
  • Because of their warm adaptation capacity, these predatory mites are considered as the ideal biological control agents for controlling whiteflies, thrips or pest mites in the US greenhouses where temperatures often exceed 25oC during summer.
  • These mites become sluggish under cooler temperatures but they can become active again when temperature rise.
  • However, these mites do not survive under really cold and frosty conditions.
  • In addition, A. swirskii do not undergo diapause due to short day-lengths or low temperatures therefore, they can be used target pests late in the fall and in the winter on indoor plants.
+ How Amblyseius swirskiia mites work in the greenhouses or fields
  • Amblyseius swirskiia are known to feed voraciously on their hosts including spider mites, thrips and whiteflies.
  • After application in the greenhouses or fields, predatory Amblyseius swirskiia starts munching on their hosts.
  • Each adult mite can consume 5 larvae of thirps or 15 larvae of whiteflies or 10 eggs of whiteflies per day.
  • These mites also consume spider mites, one of the most important pests greenhouse and field crops.
  • While feeding, mites develop and reproduce rapidly.
  • Under favorable environmental conditions and if there is enough food around, these mite can recycle continuously (do not need to apply again and again) and help to keep the pest population under economic threshold level.
+ Why you need them
  • they can reduce the crop damage by feeding on crop pests responsible for the damage
  • they can munch on different stages hosts including eggs and larvae of whiteflies and immature thrips
  • they are able to actively search for their hosts and feed on them
  • they can reproduce and continue their life cycle on the foliage after first application
  • they are commercially available and easy to apply in the greenhouses or fields
+ Why predatory mites are safer than traditional pesticides
  • they do not damage plants
  • can be used and applied around children and pets
  • do not cause any harm to the personnel involved in their production and application
  • food products are safe to handle and eat when they are treated with mites
  • they do not harm humans, animals and pollute the environment
