Corn
Nearly one out of every three dollars generated by South Dakota agriculture starts in a corn field. Two of every three rows of corn become ethanol.
Corn Rootworm Adults Are Active in South Dakota
We have been observing a lot of corn rootworm adults in South Dakota. The emergence of these primarily underground pests can provide insight into field population levels and the potential for future root injury.
Redheaded Flea Beetles Are Active in South Dakota
Redheaded flea beetles are now active in soybean. Although they haven’t caused significant defoliation yet, their activity should be monitored, as other defoliating insects are also present in soybean.
Grasshopper Activity Is Ramping Up
We have already observed increased grasshopper activity in many areas of the state and, depending on the 2022 season, they may become problematic in crops.
Tiger Beetles: Beneficial Predators and Ecosystem Health Indicators
Tiger beetles are generalist predators, meaning they prey on a wide variety of pests. Observing them in a landscape is a great sign that an ecosystem is healthy and supporting a diversity of both prey and predators.
Biocontrol Agents: Brown Lacewings
With so many insect pests causing concern for both gardeners and farmers, it’s important to know which ones are on our side. In this article, we focus on the brown lacewing and the beneficial role it plays within the landscape.
Flying Gems: Long-Legged Flies
