Pea aphid (Acyrthosiphon pisum)
In the United States, the pea aphid (Acyrthosiphon pisum, adult female and young shown here) has a broad host range and is a serious concern for commercial pulse producers, especially in the Pacific Northwest region. A new guide in the open-access Journal of Integrated Pest Management examines pea aphid biology and ecology, as well as various management practices. (Photo by Joseph Berger, Bugwood.org)
