Protecting Your Garden From Squash Bugs

Small red maggots under your soybean plants’ epidermis? We have answers.

In 2015, we received plant samples of soybean that had small red maggots under the epidermis. Now, in 2017, we are starting to receive reports of these same insects being found under the epidermis of soybean in different parts of South Dakota.

Which mite is it? Identifying the mites in wheat fields

In South Dakota, the most commonly encountered mites in wheat are wheat curl mite and brown wheat mite. In addition to feeding, wheat curl mites are vectors of Wheat streak mosaic virus. Brown wheat mites can build up large populations and injure wheat through feeding. There are other species of mites that may also be observed in wheat, but generally do not reach populations large enough to cause significant injury.
