Grass sawfly
We have not observed any grass sawfly larvae in our field surveys. This suggests that the larvae have matured and have dropped to the soil. They will form pupae in the soil in which they will remain until the following spring. We will monitor these areas for adult emergence next spring.

Wheat Stem Sawfly State-Wide Survey
Now that the adult sawflies have finished their emergence cycle, we will soon start our state-wide sawfly infestation survey. This is a large project that we strive to make as comprehensive as possible.

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.
