Phytoseiulus persimilis, hailed as one of the most formidable predators revered by growers worldwide, rises as a fierce warrior, primed to vanquish web-spinning spider mite species with deadly precision. Considered a specialist predator of the notorious two-spotted spider mites, P. Persimilis displays incredible speed and tracking abilities, intensifying its search when spider mite webbing is present. Thanks to its ability to sense odors emitted by mite-infested plants, it launches stealthy assaults, piercing the mite’s body and swiftly consuming its internal fluids, resulting in an impressive number of spider mites eradicated daily, with an estimated range of 5 to 20 eggs or mites per day under optimal conditions. Thriving in temperatures between 68-86°F with a required relative humidity over 60%, P. Persimilis emerges as the most efficient predator of two-spotted spider mites. Diligently continuing its mission, this biocontrol agent boasts an impressive reproduction rate. The adult female can lay up to 60 eggs during her approximately 50-day lifespan when temperatures average 74°F, with eggs hatching 2 to 3 days after being laid. The total development time from egg to adult ranges from about 25 days at 59°F to 5 days at 86°F, with generation times of 7 to 17 days at common field and greenhouse temperatures, twice as fast as that of its prey.
Phytoseiulus persimilis, the indefatigable biocontrol agent, defies rest with its continuous activity year-round in greenhouses, interior plantscapes, and regions with mild winter temperatures. Thanks to its lack of a diapause (resting) stage, Phytoseiulus persimilis can remain perpetually active if conditions permit, boasting multiple generations per year and making it one of the most heavily employed biocontrol products in the agricultural world.
