The predatory mite Phytoseiulus persimilis, of South American origin, is a well-known biological control agent against spider mites. P. persimilis range of distribution is worldwide.

Target Pests
P. persimilis is an obligatory predator, highly specific to spider mites like Tetranychus urticae Koch (two-spotted spidermite); Tetranychus cinnabarinus (Boisduval) (carmine spidermite); Tetranychus turkestani Ugarov & Nicolski (strawberry spidermite) and bean mite (Tetranychus ludeni), hence it cannot develop without the latter. It controls spider mite infestations in many crops, in temperate as well as subtropical and tropical regions.

Peppers, tomatoes, potatoes, beans, maize, cucumber, melon, strawberries, eggplant and ornamentals: gerbera, roses, and several pot plants.

The adult female is an orange-red pear-shaped mite rather longer than its prey. It has longer front legs and a characteristic rapid movement when disturbed or exposed to bright light. The nymphs are oval and pale-pink in colour.

BioPersimilis – The Product

  • BioPersimilis is packed in a 100 cc bottle containing a minimum of 2,000 or 4000 predatory mites mixed in a vermiculite carrier.
  • BioPersimilis can be sprinkled from the bottle over the crop or applied by especially designed distribution boxes that are hung on the plant. The former application method is good for horizontal crops whereas the latter is more effective in vertical crops.
  • If necessary, BioPersimilis can be stored for 24 hours at a temperature of 8-10°C from the minute of arrival until release, but it should never be frozen.
  • BioPersimilis is compatible with selective conventional chemicals (according to the list of compatible chemicals provided by BioBee)


  • Prior to opening, the bottle should be rotated gently while in horizontal position to allow proper mixing of the predatory mites in the vermiculite carrier.
  • BioPersimilis is shipped in isolated styrofoam boxes chilled with icepacks. This packaging must be kept intact until it reaches the end-user.
  • BioPersimilis should be introduced upon first sign of spider mite damage. The release rate depends upon the nature of the crop, the ecosystem (e.g. open field or greenhouse) and the level of spider mite infestation. Temperatures of 21-27°C and high humidity (above 60%) will enhance predator activity and ensure its success.
