Persimilis

Persimilis (Phytoseiulus persimilis)

Phytoseiulus persimilis is a predatory mite, proven outstanding, aggressive and highly effective against spider mites. In suitable conditions, persimilis can develop faster as its prey, allowing it to suppress mite infestation quickly and thoroughly. Performs especially well in strawberries and other crops where relative humidity remains above 65%

Targets Pests: Two-spotted spider mite (Tetranychus urticae), Red/Carmine spider mite (Tetranychus cinnabarinus) and related web-spinning spider mites.

The adult female is a distinctive reddish-orange color with a pear-shaped body. Its long front legs allow it to move quickly and easily navigate spider mite webs which makes it an ideal choice to control spider mites in a wide variety of crops.

Phytoseiulus persimilis is available as BioPersimilis and as BioPersi+

BioPersi+ is produced using a new alternative food system and innovative rearing method which allows for efficient, consistent and dependable production for this predatory mite.  BioPersi+, an improved version over the traditional BioPersimilis (Phytoseiulus persimilis) in many respects.

Compared to the traditional BioPersimilis, which appears as a shiny red-orange mite, BioPersi+ is white upon arrival. Yet it turns red-orange once it starts feeding on spider mites. This change in color confirms active predation and is a useful visual indicator. BioPersi+ has a higher fecundity than the traditional BioPersimilis: females lay over 19 eggs within 5 days, under favorable conditions. BioPersi+ displays better searching ability and control of spider mite hot spots of predation, an advantageous and unique visual indication to the grower.
