Amblyseius californicus

Amblyseius californicus is a predatory mite. It can be applied on various vegetables and ornamental crops in glass-covered ground against different species of mites (for example against two-spotted spider mites, cyclamen mites, fruit-tree red mites and etc.).

The adult individual is semitransparent, pale-orange, peachy or pink. The life span of the predator is 20 days. During a day at a temperature of 26°C one individual of the predator devours on an average 11.6 eggs and nymphs of the pest. The adult female is approximately 0.1 mm in length, oval, it lays from 2 to 4 eggs per day and is able to kill 150 mites for the whole period of life.

Prophylactic colonization is made every 2–3 weeks in amounts of 5–10 individuals per 1 m2. In case of the high density of pest population the additional invasion of A.californicus to the main predator Phytoseiulus persimilis is realized in amounts of 15–30individuals per 1 m2. If necessary invasions are repeated. The acariphage is active in a thermal range of 8–35°C and can be applied in outdoor planting. It is loyal to a wide range of relative air humidity (40–80%). The predator is resistant to many synthetic pesticides (acaricides, insecticides). The application of Amblyseius californicus is the most effective together with Phytoseiulus persimilis .



  • long activity because of possibility to consume alternative food,
  • the consumption of different species of phytophage mites,
  • the absence of cannibalism,
  • resistance to influence of chemicals,
  • high effectiveness for prophylactic application.
