Early season pests feeding on your profits?

Early season insects can feed on soybean seeds and seedlings causing plant injury, stunting, delayed emergence, or stand loss. Bean leaf beetle and soybean aphid both feed on young soybean plants.
Soybean aphids are small, about the size of a pinhead or smaller, yellow aphids with distinct black cornicles ("tail-pipes"). They are the only aphids to feed on soybeans in North America.
Late planted soybean fields are often at the highest risk of early soybean aphid attack. Seed treatments like Lumiderm™ insecticide seed treatment have been shown to provide effectiveness in delaying aphid increase, especially in late-planted situations.1
Bean leaf beetle adults are 1/5 inch long, typically dark yellow, but may be orange or red. Their wings often have four “rectangular” marks but may have two or no marks. They have a black triangle behind their pronotum (neck region). Larvae are white with a dark brown or black head and are found in soil near roots feeding in a nodule.
Mild winters allow for higher-than-average overwinter survival of bean leaf beetles which can reduce plant populations on early planted soybean fields. Early season feeding of bean leaf beetle adults occurs on cotyledons, leaves, and the external surface of pods. Larvae remain in the soil and feed on nodules and roots.2 Adult bean leaf beetles also can transmit a bean pod mottle virus, which reduces yield and quality and is one cause for green stem in soybeans. While feeding during the vegetative growth stages occurs, the most economic damage occurs in summer as beetles feed on pods.3
