Abstract

A rearing chamber designed to test colour preference by biotypes of pea aphid, Acyrthosiphon pisum (Harr.), indicated preferences for orange or yellow or both (615 mμ, and 595 mμ). Aphids of biotype R1 confined to chemical diets back-lighted blue or white survived only for a few days, whereas they lived longer and grew rapidly on diets lighted orange or yellow.
