It is very hard to detect the first thrips in the field. So, fast releasing Amblyseius cucumeris is recommended to keep the thrips densities as low as possible, even if no thrips have been found yet.

The predatoty mite Amblyseius cucumeris (same name Neoseiulus cucumeris) is not quite conspicuous on the leaves because its body is less than 1 mm. Only when it is moving on the surface of leaf, you can easily find it.
     This predatory mite has five different developmental stages: egg, larva, protonymph, deutonymph and adult (female or male). The female mite mates several times. She deposits 1-2 eggs daily on leaf hairs close to the veins on the underside of the leaf. The larvae can develop into protonymph without preying, but the food is necessary for development of protonymph. If there is not enough prey in the field, it can develop into adult with pollen as food. The development from egg to adult takes 8-11 days (at 20-25°C). A female Amblyseius cucumeris can lives for about 3 weeks.
      Amblyseius cucumeris can pierce their prey and suck them empty. Besides young larva of thrips, they sometimes prey on spider mites, or eggs and larvae of other predatory mites, for example Phytoseiulus persimilisAmblyseius cucumeris prefers first instar thrips.
