Due to its tropical origin, P. persimilis does not have a diapause stage and is active year-round in enclosed habitats such as interior plantscapes and greenhouses. P. persimilis are very voracious. They have the highest consumption rate of all phytoseiids. It is also used in interior plantscapes and conservatories. Greenhouse ornamentals growers have long relied on its ability to control spider mites.
Humidity strongly impacts P. persimilis' efficacy.
When P. persimilis contacts spider mite webbing, it intensifies its search for prey. P. persimilis has high dispersal ability and its distribution is highly correlated to that of its prey. However, its ability to disperse is dependent on the environment. If infested plants' leaves touch, dispersal is possible. P. persimilis moves upward on the plant in search of prey and disperses when prey is scarce.
