Imagine a pest that can arrive unannounced, suck your soybean plants dry and then double in numbers in two days. Behold the soybean aphid. This native of Eastern Asia can pack a heavy punch and knock the top of your soybean yields.
Adult soybean aphids are small (less than 1/16" in length), yellow- bodied insects with distinct black cornicles or “tailpipes.” They can be either winged or wingless.
