Corn leaf aphids are showing up in fields in South Dakota, and corn growers should start scouting their fields as soon as possible.

The announcement came in a press release from South Dakota State University.

"Right now, the goal is to go out and scout fields. They need to be scouted starting at tasseling stage," said Jon Kieckhefer, an Extension agronomy educator based in Brookings County. "Look for aphids in the whorls of the plants or on the tassels."

Extension agronomy educator Roger Barrick reported on July 22 that corn leaf aphid populations are just getting established on tasseling corn in Charles Mix County.

The highest population observed was 10 percent of the corn plants infested with 20-30 corn leaf aphids per plant.

Aphids can reproduce very rapidly on corn, and in large numbers can cause some significant yield losses. Recent research in South Dakota suggests that colonization of about 10 percent of corn plants starting at V-10 or just before tasseling may significantly impact yield.

South Dakota Cooperative Extension entomologist Mike Catangui said that corn leaf aphids are an emerging insect pest of both Bt-corn and conventional corn in South Dakota.

"There is a growing scientific evidence that Bt-corn may, in fact, be the preferred host of corn leaf aphids," Catangui said. "Corn leaf aphids have syringe-like mouthparts and feed on the sap of corn, and when numerous, they can cause wilting and can severely interfere with pollination, resulting in small and 'barren' corn ears at harvest."
