Spider Mite Control with Predatory Mites (Neoseiulus californicus)

Video: Spider Mite Control with Predatory Mites (Neoseiulus californicus)

The predatory mite Neoseiulus californicus is an effective natural enemy of various species of spider mites, including the two-spotted spider mite (Tetranychus urticae). As a key player in biological pest control, this predator helps growers protect their crops sustainably.

How does Neoseiulus californicus work?

•Specializes in targeting the larval and nymphal stages of spider mites.

•Also consumes spider mite eggs, ensuring population control.

•Detects prey through webbing and leaf damage rather than sight.

•Feeds by sucking out the contents of its prey.

Why use Neoseiulus californicus for spider mite control?

•Highly adaptable to different environments, including warm and dry conditions.

•Works as both a preventive and curative solution for spider mite infestations.

•Complements other predatory mites, such as Phytoseiulus persimilis, for integrated pest management (IPM).

•A natural, sustainable alternative to chemical pesticides.
