A guide to separating Aphis glycines Matsumura and morphologically similar species that share its hosts

Abstract

Aphis glycines Matsumura shares its hosts with two other aphid species, Aphis nasturtii Kaltenbach and Aphis gossypii Glover. Tables of characters and photographs are provided to assist in the separation of these three species. A photographic plate showing a gynopara, male, ovipara, and late summer apterous vivipara of A. glycines is included. © 2004 Entomological Society of America.
