Cucumeris is a species of predatory mite that feeds on immature stages of thrips. It also feeds on pollen, two spotted mites and other species of mites. Cucumeris adults are pear-shaped, tan colored mites, less than 0.5mm (1/50 inch) long. When these pests aren't around A. cucumeris survive by eating  pollen.

Product information:
About 60% are female. Well-fed females will lay up to 3 eggs per day for approximately a month. Their eggs are tiny .01 round, transparent and usually deposited on the bottom of leaves. Cucumeris are shipped as adults, immatures and eggs. They are available in two types of packaging:

Bulk bottles - containing 50,000 or 250,000 live adult predators. Release adults if an infestation already exists. Can be releases as a preventative measure as well, since cucumeris will survive in the absence of prey by feeding on pollen.

To release adults: Upon receipt allow A.cucumeris to warm to room temperatures. Predatory mites should be seen on the underside of the lids. Open the lid and shake the contents onto leaves or at the base of plant stems.  

Slow release hanging sachets bags - containing approximately 1,000 A.cucumeris predatory mites and a food source. The bags are designed to be breeding habitats and are hung on plants. Over four weeks, each bag can produce over 1,000 predators.

Slow release hanging sachets are a Great option for preventative maintenance to guard against Mites or Thrips. Simply hang every 4 weeks and these hatching bags will breed your own natural enemies.

Lifespan of Cucumeris:
A complete life cycle takes 10-12 days
. They feed 7 days before becoming adults. Adults live for up to 30 days.

Strategic Considerations:
For a more complete Natural and Organic control of Thrip u
se Cucumeris alongside predators; Orius (pirate bug), Hypoaspis and Beneficial Nematode - Steinernema feltiae.

For a more complete Natural and Organic control of Spider Mites, Russet Mites, Rust Mites, Two-Spotted Spider Mites, Cyclamen mites use Cucumeris alongside predators: Special Blend Predatory Mites, Phytoseiulus persimilis, Amblyseius andersoni, Neoseiulus fallacis and Amblyseius swirskii.
