Alate Aphids Captured in Yellow Pans Placed around a Corn Field in Northeast Mississippi

Abstract

Yellow pan traps containing water were used to collect alate aphids around the periphery of a corn field located in northeast Mississippi. A total of 35 aphid species in 15 genera was captured in 10 traps during May through August 1969. Eighty-six percent of the trapped aphids were composed of 4 species: the pea aphid, Acyrthosiphon pisum (Harris) (51.3%); the spirea aphid, Aphis spiraecola Patch (15.0%); the corn root aphid, Aphis maidiradicis (Forbes) (10.1%) and the green peach aphid, Myzus persicae (Sulz.) (9.3%). Four other species accounted for 6.8% of the total aphid collection: the bean aphid, Aphis fabae Scopoli (2.9%); the ambrosia aphid, Dactynotus ambrosia (Thos.) (1.6%); Capitophorus braggii (Gill.) (1.2%); and Myzocallis multisetis (Tiss. & Boud.) (1.1%). Aphid activity was highest during May and August.
