Coccinellidae (Coleoptera), Chrysopidae and Hemerobiidae (Neuroptera) species of gall-making aphid species on Ulmus glabra Mill. were investigated during 2001 in Ankara in the present study. There are three important gall-making aphid species in Ankara. These are: Eriosoma lanuginosum (Hartig), E. ulmi (L.) and Tetraneura ulmi (L.). Four species and 1 subspecies from the family Coccinellidae, 1 species from the family Chrysopidae and 2 species from the family Hemerobiidae were detected as the species feeding on the gall-making aphids on elm in Ankara. These species are: Adalia bipunctata (L.), A. fasciatopunctata revelierei (Muls.), Exochomus quadripustulatus (L.), Scymnus apetzi (Mulsant), S. rubromaculatus (Goeze) (Coccinellidae), Cunctochrysa albolineata Killington (Chrysopidae), Sympherobius pygmaeus (Rambur) and Wesmaelius subnebulosus (Stephens) (Hemerobiidae). More coccinellids were detected than neuropters as predators of gall-making aphids on elm. E. quadripustulatus was the most commonly found predator among the coccinellid species and this was followed by A. bipunctata while S. rubromaculatus was the less commonly found species. C. albolineata was the most commonly found predator among the neuropter species detected. Coccinellids were mostly found in the galls formed by E. lanuginosum.
