Integrated Crop Management News

Publication Date



In a 2006 article published in the journal Environmental Entomology, Purdue University entomologists Nicolas Desneux, Bob O'Neil, and Ho Jung Yoo identified Orius insidiosus as the key, or #1, predator of soybean aphids in Indiana. Orius insidiosus, also known as the insidious flower bug, which is similar but not the same as the minute pirate bug, is a tiny true bug, black in color with partially black-yellow-white wings, and a piercing, sucking mouthpart. Many of our readers may not immediately recognize this insect based on this description, but if you've ever been in a corn field during October, these small black insects have probably bitten you and left a strong mental impression as the burning sensation from the bite greatly exceeds the diminutive size of the insect. In other words--little bug, big bite.
