İspir ve yöresinde yetiştirilen meyve ağaçlarında Dysaphis devecta (Walker), D. plantaginea (Passerini), Aphis craccivora Koch, Anuraphis subterranea (Walker), Ovatus crataegarius (Walker), Hyalopterus pruni (Geoffroy), Brachycaudus cardui (Linnaeus), Myzus cerasi (Fabricius), M. lythri (Schrank), Corylobium avellanae (Schrank), Chromaphis juglandicola (Kaltenbach) ve Callaphis juglandis (Goeze) olmak üzere 12 yaprakbiti türü saptanmıştır. Bunlardan H. pruni ve A. craccivora’nın daha yaygın ve daha yüksek popülasyona sahip olduğu gözlenmiştir. Çalışmada, Adalia bipunctata (L.), A. decempunctata (L.), A. fasciatopunctata revelierei Muls., Adonia variegata (Goeze), Coccinella septempunctata L., Exochomus quadripustulatus (L.), Propylaea quatuordecimpunctata (L.), Scymnus (Pullus) subvillosus (Goeze), Synharmonia conglodata (L.), Vibidia duodecimguttata (Poda) (Coccinellidae); Syrphus ribesii (L.), Episyrphus balteatus (De Geer), Paragus quadrifasciatus Meigen, Eupeodes corollae (F.) (Syrphidae) ve Chrysoperla carnea (Stephens) (Chrysopidae) olmak üzere 15 predatör; Alloxista sp., Praon dorsale (Hal) veP. volucre (Hal.)
