  • For greenhouse crops, tropical plants, bedding plants, and large agri-business
  • Feeds on a variety of pest mites

Neoseiulus californicus

Although these predatory mites consume their prey at a more leisurely pace than do their friends Mesoseiulus longipes and Phytoseiulus persimilis-- one adult or a few eggs per day -- they can survive longer under starvation conditions.

N. californicus need a minimum of 60% humidity and like temperatures 60-85 degrees F.

It completes a generation in 4 to 12 days depending on the average temperature (12 days at 64øF, 4 days at 90øF). It lays about 3 eggs per day for 2 weeks and it lives about 20 days. At 77øF the female N. californicus can consume 5.3 Spider mites eggs/day. It feeds on a variety of pest mites including the 2 Spotted Mite, Pacific mite and the Cyclamen mite.

Release rates: 4 mites/sq. ft, bi-weekly, 2-3 times; 5,000-20,000/acre, bi-weekly, 2-3 times. Works great in gardens, greenhouses, strawberries, ornamentals and roses.

Mesoseiulus longipes

These predators are similar to P. persimilis but can tolerate lower humidity (40% at 70 degrees F). Longipes are effective in temperatures up to 100 degrees F, although a comparable increase in humidity is required. Apply these predators in warm greenhouses and interiorscapes with artificial lighting. The lifespan of the adults, the form in which they are shipped, is 34 days.

Release rates: 
indoors, 3/sq. ft. bi-weekly, 3-5 times; 
outdoors, 5,000-20,000/acre, bi-weekly, 3-4 times.

Phytoseilus persimilis

Two-spotted spider mites (Tetranychus urticae) and several other pest mites are the target food of P. persimilis, which will consume 5-10 pest adults or up to 20 pest eggs/day. When released during a low infestation, spider mites can be controlled within 2-3 weeks. P. persimilis need a relative humidity greater than 60% in order to survive, especially in the egg stage. Once the adults' food supply dwindles, P. persimilis die. If reinfestation occurs, P. persimilis must be reintroduced, preferably every 3-5 weeks, or in combination with other predatious mites. 

Release rates: 
for tomatoes and cucumbers, 1 predator/plant plus 1-2/infested leaf; 
for other greenhouse crops and tropical plants, 2,000/3,000 sq. ft; 
for bedding plants, 1,000/10,000 sq. ft.; 
for large agri-business, 5,000-20,000/acre depending on infestation.
Availability: year-round
