Cowpea Aphids Showing Up in North Central Kansas

KSU ENTOMOLOGY – We have started finding a few cowpea aphids on alfalfa stems in north central Kansas. However, there are also many lady beetles, lacewings, and mummies, which indicate parasitoid activity, present. Aphid populations can increase rapidly and swathing will remove many aphids, but not all of them. So fields should be rechecked weekly. More Information and photos are available in the August 14, 2015, issue of the Kansas Insect Newsletter.
