Population dynamics of Melanaphis donacis (Hemiptera: Aphididae) and its Coccinellidae and Syrphidae predators on Arundo donax L.
Abstract The population density of the aphid Melanaphis donacis (Passerini) was studied in experimental plots of Arundo donax (L.) at the Antumapu Campus of the University of Chile, La Pintana (33° 34' 08” S 70° 38' 40” W) and on wild populations at Rinconada de Maipú (...
