Brown Wheat Mite Affecting South Dakota Wheat

Recently, there have been reports of brown wheat mites throughout central and western South Dakota. The brown wheat mite is generally more of an issue in the drier parts of the state, or in areas experiencing drought. The feeding injury caused by these mites leaves white or brown spots that are referred to as stippling.

Overwintering S.D. Bean Leaf Beetles: 2017 predicted mortality

The overwintering generation of bean leaf beetle adults emerge in the spring and can cause serious defoliation injury to seedling soybean plants. However, the abundance of overwintering bean leaf beetles is negatively affected when the air temperatures get too cold. Therefore, an estimate of the emerging populations can be made based on how cold the winter was.

Fall Household Pests

Fall is here, but many insects are still active – especially on unseasonably warm days. Southern exposures of buildings are a common gathering spot for insects.

Managing Wheat Curl Mite

Wheat curl mite is one of the more difficult pests to manage in wheat. This is in part due to the limited options available for preventing populations from infesting a field and rapidly reproducing.

Sod Webworm in South Dakota

Sod webworm moths are emerging throughout South Dakota. Although these pests are common during the fall, the number of moth sightings and population densities in the Western half of the state are higher than normal. The particular species being found is the vagabond sod webworm. Unlike several other webworm species found in the United States, vagabond sod webworms rarely cause much damage and the adult moths are no more than just a short-term nuisance.

Scouting Winter Wheat for Aphid Pests

Although we cannot predict aphid pressure in winter wheat, there are measures that may be taken to reduce the risk associated with these insects.

I Found a Praying Mantis, Now What?

Praying mantises are one of the most distinctive large insects that can be found in South Dakota. Their striking appearance, size and perceived rarity contributes to the frequent calls and emails that we receive regarding sightings and captures of these insects.
