Diaeretiella rapae, a parasitoid that predominately specializes in the parasitism of Brassica-feeding aphids, attacks Lipaphis erysimi, a specialist feeding aphid of the Brassicaceae and other families in the Capparales, at a greater rate than the generalist-feeding aphid, Myzus persicae. In this study, we investigated the orientation behavior of D. rapae to the volatile chemicals produced when these two aphid species feed on turnip (Brassica rapa var rapifera). We showed no significant… CONTINUE READING
