Neoseiulus cucumeris

Neoseiulus cucumeris predatory mite


Neoseiulus cucumeris is a predatory mite used to suppress immature thrips, two-spotted spider mites, cyclamen (or strawberry) mites (Phytonemus pallidus), broad mites (Polyphagotarsonemus latus) and mites of the genus Schizotetranychus in ornamental, fruit and market garden crops.

Adults are pear-shaped, 0.5 mm long, with long legs. The eggs are round and transparent and measure 0.14 mm in diameter. These mites lay their eggs on leaf hairs (trichomes) and along the veins on the inner surface of leaves. The eggs hatch about 3 days later.

Neoseiulus cucumeris attacks immature stages of Onion thrips (Thrips tabaci) and Western flower thrips (Frankliniella occidentalis). Control results are observed after 3 weeks. Etablishment of Neoseiulus cucumeris requires 4-8 weeks when ideal contitions are present.

In absence of prey, Neoseiulus cucumeris feed on eggs and immature stage of Phytoseiulus persimilis. It can be used with the soil mite Stratiolaelaps scimitus, Dalotia (Atheta) coriaria and withOrius insidiosus.
