Effective against two-spotted spider mite
What does PHYTOSEIULUS PERSIMILIS look like?
The adult predatory mites are pear-shaped, shiny and bright red with four pairs of legs. Young stages are translucent to light red and have three pairs of legs. The eggs are oval, light pink, shiny and translucent. All stages of the predatory mite (except eggs) move very quickly over the leaves.
How does PHYTOSEIULUS PERSIMILIS work?
PHYTOSEIULUS PERSIMILIS predates on all stages of two spotted spider mite (Tetranychus urticae). The carmine spider mite (Tetrancychus cinnabarinus) is eaten to a much lesser extent. The number of mites that are eaten depends on the spider mite abundance, relative humidity and temperature. PHYTOSEIULUS PERSIMILIS is mainly used in spider mite hot spots. At low spider mite abundance, cannibalization between spider mites can occur. At 20°C adult predatory mites kill five adult spider mites or twenty young larvae and eggs a day. The development of predatory mites is twice as fast as spider mite development at 20°C. PHYTOSEIULUS PERSIMILIS that we produce ourselves is effective at low humidity, starting at 40%. This makes PHYTOSEIULUS PERSIMILIS different from SPIDEX as SPIDEX is only effective from 60% relative humidity.
When can PHYTOSEIULUS PERSIMILIS be applied?
PHYTOSEIULUS PERSIMILIS is used in greenhouses and indoor plantings to control two–spotted spider mite (Tetranychus urticae). This product is also effective under relative dry conditions that may occur in indoor plantings. The dried bean leaves are best placed at the base of contaminated sticks or leaves. The predatory mites will find their way to the pest hot spots. Consider multiple introductions. The product is sensitive to several chemical pesticides. Ask advice for deployment strategies.
