Amblyseius californicus can be used in several vegetables, fruits and ornamental crops, for emaple, eggplant, anthurium, chrysant, cucumber, grape, haricot bean, melon, rose, strawberry, sweet pepper, tree nurseries.
Two spotted spider mite (Tetranychus urticae), carmine spider mite (Tetranychus cinnabarinus, Tetranychus truncates), strawberry spider mite (Tetranychus turkestani), fruit spider mite (Panonychus ulmi), citrus red mite (Panonynchus citri), Oriental red mite (Eutetranychus orientalis), begonia mite (Tarsonemus pallidus) and broad mite (Polyphagotarsonemus latus), grape erineum mite (Colomerus vitis). All stages, preferring younger stages. Predatory mites also survive on other mites and pollen and can survive for a number of weeks without food.
                                         The method of releasing Amblyseius californicus

Amblyseius californicus Rate
(individuals/ m²)
Frequence Remarks
Preventive 25/m² 1000 m² 1 when spider mites is absent
curative light 100/m² 250 m² 1 start when spider mites is present (only 1-2 female per leaf)
curative heavy 200/m² 125 m² 1 infested areas only, always in combination with other beneficials
In crops where it is very hard to detect the first spider mites, whereas, spider mites can increase their population very rapidly, especially under dry and warm conditions. So, fast releasing Amblyseius californicus is recommended to keep the spider mite densities as low as possible, even if no spider mites have been found yet.
         Female Amblyseius californicus                    Releasing Amblyseius californicus
Before releasing, turn and shake gently the bottle
Open the cap, or press on centre of cap to open dosage hole
Pour-out the material inside bottle on leaves
1 releasing points per square meter is necessary, or evenly distributed over the total surface
Storage and handling
If you have received the packaging of this predatory mite, please release them as soon as possible, because you know biological beneficials have a short life expectancy. Storing them for a long time has a negative influence of their quality. Low temperatures also have a negative influence on Amblyseius californicus.  BESTmites co. ltd. is not liable for any loss of quality if the product is stored for longer than recommended and/or under incorrect conditions. If necessary, please store them under the conditions described below.

·     Storage after receipt: 5days
·     Ideal storage temperature: 10°C
·     In the dark with enough ventilation to avoid CO2 accumulation
Apply preventive introduction on pollen only from the moment when crop flowers continuously. Amblyseius californicus tolerates a range of chemical pesticides, whereas, in any case please careful reading the side effects of different pesticide to this predatory mite in our website. 
Amblyseius californicus is more important predator for spider mite control relative to Phytoseiulus persimilis, as it offers the following advantages:

·     Since Amblyseius californicus can starve for a longer time, its population will always be present in the crop. So, there is no need to repeat the introduction as Phytoseiulus persimilis.
·     This results in a lower cost.
·     Amblyseius californicus can be used as preventative measure, due to it is not cannibalistic relative to Phytoseiulus persimilis.
·     Amblyseius californicus is not as temperature dependant as Phytoseiulus persimilis, is active at temperatures from 8°C to 35°C (and no problem in short time of high temperature  40°C) and can be applied outdoors. Especially in crops where high temperature and/or relative humidity variations occur, Amblyseius californicus will perform much better than Phytoseiulus persimilis.
·     Amblyseius californicus is more resistant to chemical pesticides than Phytoseiulus persimilis.
·     Amblyseius californicus can be used to control wide range of spider mites, not only Tetranychus, but also Panonychus, Eutetranychus, Tarsonemus, Polyphagotarsonemus and Colomerus in many crops.
·     Amblyseius californicus is not sensitive to day length (no diapause).
·     Amblyseius californicus can survive on pollen.

The predatoty mite Amblyseius californicus (same name Neoseiulus californicus) can be easily found in strawberries, citrus and ornamentals in California and Florida. It is a germane predatory mite with spider mites in nature, but as a polyphagous predatory mite, it can also prey on tarsonemid mites and pollen.
      Amblyseius californicus have five different developmental stages: egg, larva, protonymph, deutonymph and adult (female or male). The predatory mites complete its life cycle within 4-5 days at 25°C. At the same temperature, the life cycle of the spider mite is twice as long as Amblyseius californicus. This species is very mobile, even under lower temperature. Not susceptible to diapause for Amblyseius californicus. So it can be use in winter.
       The female adult predatory mite can live about 20-40 days at 25°C. Its oviposition duration is over 14 days (with an average of 3-4 eggs per day with spider mites as prey). A female Amblyseius californicus can consume daily 5 adult spider mites and also eats some eggs and nymphs, preferring eggs or larvae of spider mites. Especially, Amblyseius californicus can survive about 14 days without eating, if in the field there are some pollen, it can survive longer time. In addition, it can tolerate high temperatures and low humidities.
Amblyseius californicus will increase its population very fast and spread among the crop as long as the ideal circumstances. You can find it on the entire plant (nearby the main or lateral veins of leaves or in the flowers). To stimulate the spread among the crop, it is recommended to disperse the mites well. The gland hairs and spider webs on leaf will not obstruct its mobility.
      Although you can easily find it on the leaves, it is very difficult to distinguish Amblyseius californicus from other predatory mites in the field, such as Amblyseius cucumeris or Amblyseius swirskii.
