P.Persimiliis 35% M. Longipes 35% N. Californicus 30%
Phytoseiulus persimilis This bright orange predator is native to the tropics of South America. It does best in a humid environment of 60 to 90% relative humidity. Does best where tempertures remain below 90 degrees F. Persimilis is sensitive to high tempertures and low relative humidity. A humidity of 60% or lower has a negative effet on the hatching of the eggs and the development of Persimilis. Persimilis can reduce spider mite population to very low numbers in two to three weeks. Since Persimilis are faster and stronger than their prey they easily catch and eat them. When released they smell their prey, then move quickly throughout the plant. Persimilis work best from tempertures of 50 t0 90 degrees F. They then die from lack of food. In situations where the pest reinfest the plants, we suggest introducing persimilis every 3 to 5 weeks.
Mesoseiulus longipes is similar to P. persimilis but can tolerate lower humidity 40% at 70 degrees F. but requires higher humidity as tempertures increase. M. 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, 1-2 times; outdoors, 5,000-20,000/acre, bi-weekly, 1-2 times.
Neoseiulus californicus 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 and can also live on a diet of pollen. In plants where it is very hard to detect the first spider mites, Californicus may be introduced preventatively; the female can consume 5.3 spidermite eggs per day. Does best in warm humid conditions, but will also tolerate low humidity (40% - 80% RH at 50° - 105°F).. Releases of californicus can be made when Spider mites are present and laying eggs. Even if no spider mites have been found yet. N. californicus need a minimum of 40% humidity and ideal temperatures 60-90 degrees F. Can tolerate temperatures up to 105 degrees F. Work’s great in gardens and greenhouses.
