Description:

ATTACKS ALL STAGES OF TWO-SPOTTED SPIDER MITES!! 

The lifespan of Persimilis is about a week in their immature stages, then around a month as adults. "Persimilis" is a predatory mite that was one of the first biological insects available commercially for Two-Spotted Spider Mites. Adults are tiny (.3 mm long), fast-moving, red, pear-shaped mites with noticeably long legs. Immature stages are a pale salmon color. Eggs are oval and 0.3mm long. Phytoseiulus Persimilis feed on all stages of Two Spotted Mites. Unlike its natural enemy, the Two-Spotted Spider Mites, Persimilis does not spin webbing.

Product Information:

Persimilis is packed in vermiculite or on bean leaves. Release Persimilis at the first sign of spider mite infestation.

Temperature:

Temperature range from 43-90 degrees F. It is best to apply Persimilis the same day as received. If storage is necessary, keep Persimilis at 50-59 degrees F.

Upon receipt of this product, Persimilis should be visible on the underside of the lid. Allow Persimilis 15-30 minutes to warm to room temperature before looking under the lid.

Release Rates: 2-4 Mites per sq. ft. or 20 Mites per infested leaf, biweekly, 3-4 times.

Lifespan:

A complete life cycle can take as little as 5 days depending on the temperature. Similar to the Two-Spotted SPider Mite, the warmer the temperature the faster they reproduce. Females outnumber the males 4:1. Females lay up to 3 eggs per in their 35-day lifetime. The eggs take a few days to hatch and are oval and 2x the size of two-spotted mite eggs. Each Persimilis eats 5-30 Spider Mite adults or eggs per day. Because Persimilis do not diapause (go into hibernation) they can be used year-round in greenhouses and climates that remain warm all year.

Strategic Considerations:

Persimilis needs relative humidities greater than 60%. In low humidity conditions, raise the humidity by lightly misting plants or wetting walkways.
