Phytoseiulus persimilus
(Two-spotted spider mite predator)

Persimilis is a tropical predatory mite that was one of the first greenhouse biological control agents available commercially.

Both adult and immature predators move rapidly over the leaves and both feed on two-spotted mite eggs, nymphs and adults. Unlike its prey, Persimilis does not spin webbing.

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.

General Introduction Rates:
5 Persimilis/10 sq. ft. or 20 Persimilis/infested leaf, weekly as needed. Apply predators to each infested plant.

Greenhouse cucumbers:
6 Persimilis/10 sq. ft. or 100 Persimilis/infested plant, weekly or as needed. Larger areas use 60,000 Persimilis/hectare (24,000 per acre).

Greenhouse tomatoes -
apply a ratio of 1 predator to 10-20 spider mites.
