The recent cold weather also played havoc with these aphids (Fig. 3). However, many aphids, in untreated fields, were just “knocked off” or left the plants and are still alive, but in the leaf litter or residue under the foliage. There are also lady beetle larvae feeding on these aphids so, hopefully, these aphid populations won’t come back as dense as they were previous to the cold weather.
