The product

SPIDEX

What does SPIDEX look like? 

The product SPIDEX contains the predatory mite Phytoseiulus persimilis. 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 SPIDEX 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 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.  

When can SPIDEX be applied? 

SPIDEX can be used in greenhouses and indoor plantings for the biological control of greenhouse spider mites (Tetranychus urticae). The product works optimally at a humidity of at least 60%. If spider mite damage is so severe that webs can be found, SPIDEX is the ideal product. If the spider mite infestation is still in the initial stage, you can also combine it with SPICAL. These are predatory mites that survive on various prey. They can therefore stay alive in the crop, even if spider mites are (nearly) absent. Be aware of repeated introductions when using SPIDEX. The product is sensitive to various chemical crop protection agents. Ask advice for deployment strategy.
