THRIPEX, Amblyseius cucumeris

Neoseiulus cucumeris, predatory mite against thrips and mites
Adult mites are about 0.4 mm long, pale-pink and have short legs. Their body is pear-shaped and somewhat flattened. They are difficult to see in the crop. The nymphs are pale brown in color. Nymphs and adults are very mobile. The eggs are translucent white.

Mode of action:

The predatory mites pierce their prey and suck it dry. Besides thrips Neoseiulus cucumeris also eats pollen and mites, spider mites, among others. This is important because this allows the predatory mites to survive in the absence of thrips larvae on plants in the greenhouse. Neoseiulus cucumeris can be used preventively.


The predatory mite is used in greenhouses and indoor landscapes against thrips, but also against two spotted spider mite (Tetranychus urticae), broad mite (Polyphagotarsonemus latus), cyclamen mite (Tarsonemus pallidus), citrus mite (Panonychus citri) and Brevipalpus mite. Consider repeated introductions. The product is sensitive to various chemical pesticides. Ask for advice on introduction strategy.
