Does Your Field Have Western Bean Cutworm larva?

Over the past few weeks, we have been receiving calls, emails and texts about finding large caterpillars feeding on corn ears (see photo).  In most cases, these are turning out to be Western bean cutworms.  Although our numbers have been about the same as previous years, we may have seen slightly more survival. This may be due to the drier and milder July, as well as delayed and patchy corn maturity which provided a lot oviposition sources. To be clear, none of this damage appears to be economic, but yet it would be important to note for future years if you have found these larvae in your field. While it is too late to control for WBC (once they enter the ear, they are protected against insecticide), knowing where larvae have been found would be good information as we continue to monitor this emerging corn pest in Ohio.

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.
