New colour changing spider mite predators - Dragonfli

Improved Phytoseiulus persimilis Predators Change Colour After Feeding On Spider Mites!

The Spider Mite predatory mite; Phytoseiulus persimiliswas one of the first successful biological controls introduced, providing natural and chemical free control of Red Spider Mites. These predators have now had a significant product upgrade with an improved rearing system, which provides them food during production and transportation. This results in the predators having much higher energy levels when they are released, enabling them to locate Spider Mites much more quickly. The extra nutrition early in their life also improves their egg laying capacity with the predators producing eggs very soon after they are applied to plants. This means that predator populations build up faster, leading to quicker control of Red Spider Mites.

This new way of producing predatory mites has one very striking characteristic, the predators change colour after feeding on spider mites, changing from white to red, providing tangible evidence that they are they are feeding on lots of Red Spider Mites!


The Phytoseiulus persimilis predatory mite changes from a transparent white colour to red after successful predation of Red Spider Mites!

This new, improved biological control for Red Spider Mite will be available in all bottles of our Phytoseiulus persimilis - Spider Mite Curative System product going forward.

Don’t be alarmed if your Phytoseiulus persimilismites are not red when they arrive in the bottle, as most will be white in colour on arrival and will only turn red once they begin feeding on the Spider Mites.

Our Phytoseiulus persimilis bottles will now contain this new and improved predator. Purchase your bottle here.
