How Do I Keep Insects From Destroying My Garden Produce?

It is not unusual to see insects in a garden during the fall, but it can be frustrating to watch nearly ripe produce be destroyed by insects before it can be picked.

Grasshoppers May Be an Issue for Winter Wheat This Fall

We have recently observed large populations of grasshoppers in Southeast and Western South Dakota. Due to their destructive feeding habits, it is very important to monitor their populations prior to and during winter wheat planting.

Huge Wasps on My Tree! No, Those Still Aren’t Murder Hornets.

Another insect that has been mistaken for the Asian giant hornet (also known by its media-popularized name of ‘murder hornet’) is the horntail wasp. Horntail wasps are wood-boring insects that are harmless to humans, as they do not have venom and cannot sting.

Monitor Soybean for Redheaded Flea Beetle Feeding

An additional soybean defoliator to monitor this week is the redheaded flea beetle. Although these beetles are typically not a serious soybean pest, large populations can result in considerable defoliation.

Squash Bugs Are Active and Ready to Kill Your Plants

Squash bugs are a headache for gardeners almost every year in South Dakota. As their name implies, squash bugs feed on squash along with many other cucurbits. Injury caused by extensive feeding appears as wilting and may result in the death of infested plants.

Monitor Sunflower for Banded Sunflower Moth Activity

Banded sunflower moths are active in South Dakota, which means it is time to start scouting sunflowers for their eggs. Banded sunflower moth caterpillars can reduce yields and oil content by feeding on the developing florets and tunneling into developing seeds.

Giant Wasps Are Invading My Yard! No, They Still Aren’t Murder Hornets.

Every year we receive multiple reports of giant wasps that seem to invade yards and gardens. These wasps aren’t the same as the so-called "murder hornets," but are actually cicada killer wasps.

What Are These Small White Insects in My Soybean Field?

During the last two weeks we have received reports of increasing numbers of small white insects present on soybean. The insects in question are whiteflies.

Dry Conditions Are Ideal for Spider Mite Activity

Several counties in South Dakota are experiencing dryer than normal conditions, therefore, it is important to monitor crops for spider mites, as they thrive during periods of dry weather.

Start Scouting for Grasshopper Activity in Crops and Grasslands

Most of Eastern South Dakota is experiencing very low grasshopper populations. However, this is not the case for many areas in Central and Western South Dakota.
