Description: “Persimilis” is a tropical predatory mite that was one of the first greenhouse biological control agents available commercially. Adults are bright reddish-orange in color, with long legs and pear-shaped bodies (about 0.5mm long). Immature predators are a pale salmon color. Eggs are oval and about 0.3mm long, which is about twice the size of the spider mite eggs
Introduction Rates: Persimilis is most effective when applied at the first sign of a two-spotted mite infestation. Because of its high reproduction rate, persimilis usually exhausts its food supply and eventually dies out. Therefore, repeated introductions are recommended until all sites with spider mite infestations have persimilis present.
For Best Results: If spider mite numbers are high (there is visible webbing and clusters of mites stringing down from leaves), use a compatible pesticide such as fenbutatin oxide or insecticidal soap before releasing predators.
