Amblyseius cucumeris

Predatory Mite of Thrips

Identification and Biology : A. cucumeris is a transparent pale brown predatory mite of about 0.5 mm long.  Larvae, nymphs and adults are droplet shaped.  The eggs are oval and transparent white and are deposited on hairs on the underside of leaves.

Mode of action: The nymphs and adults of A. cucumeris feed on young thrips larvae (mainly first instar).  It also feeds on pollen, two-spotted mites and other mites.

Introduction method and release rates: A. cucumeris can be introduced in different ways.  1) Sprinkle the bran (bulk) on the plants. 2) apply 2.5 ml (Breeding systems) with a spoon on the rockwool block.  When the Breeder System is introduced on the rockwool block, the heaps of the bran will produce A. cucumeris for few weeks.  On plants that procude pollen one introduction should be enough to get A. cucumeris established.  It is important to introduce A. cucumeris before thrips have reached damaging levels.  Preventive:  50 A. cucumeris/m2.  Curative:  100 A. cucumeris/m2.

Storage: Introduce the beneficials as soon as possible after receipt. If storage is necessary, keep them at 12 – 15 °C (54 – 59 °F).
