Amblyseius cucumeris

13

Amblyseius cucumeris is a predatory mite. Its size is up to 1 mm in lengthand it has a beige color. The predator is mainly applied against thrips for protection of decorative flowers (herberas, chrysanthemum, roses etc.) and vegetables (cucumber, sweet pepper, eggplant). It also can be used for the control of Tarsonemid mites on some agricultural crops. A. cucumeris is also able to consume the spider mite. The female lays about 35 eggs for its life cycle near veins on the underside of a leaf blade. The adult Amblyseius cucucmeris lives about 3 weeks. The adult predator consumes on an average 1 thrips per day and in addition a spider mite and its eggs.

The prophylactic colonization is based on the application of special paper water-resistant packs (Controlled Release System (CRS)), which contains nutrient substratum (bran and vermiculite). As a rule a pack contains about 500 or 1000 individuals of the entomophage in different stages. The pack has an outlet for the gradual releasing of the predator. Amblyseius cucucmeris goes out during the long period of time ensuring the permanent presence of predators on crops within the whole term of pack application (4–6 weeks in dependence on conditions).

It is not recommended to use the entomophage under permanent low temperatures (10°C) and in very dry conditions (at a relative air humidity of lower than 50%). Hydrothermal conditions for the optimal effectiveness of the predator are temperatures of 20–25°C, a relative air humidity of 65–75%.

Advantages

  • effective application on many of crops,
  • easy and handy to apply,
  • the long action of the predator,
  • the absence of diapause,
  • the high level of mobility.
