The Economics of Aphids Infestations

There are both wingless and winged forms, according to Matt O’Neal, assistant professor, Entomology. He says wingless soybean aphid adults are about 1⁄16 inch in length, pale yellow or green, and have dark-tipped cornicles (tail pipes) near the end of the abdomen. The winged form has a shiny black head and thorax with a dark green abdomen and black cornicles.
