Turkish. Bu çalýþma Pistacia türlerinde gal oluþturan yaprakbiti türleri, yayýlýþ alanlarý ve doðal düþmanlarýnýn belirlenmesi amacýyla 2010-2011 yýllarýnda Gaziantep ve Þanlýurfa illerinde yürütülmüþtür. Bu amaçla, Gaziantep ilinde 6 ilçede 34 köyde, Þanlýurfa'da 5 ilçede 44 köyde çalýþma yapýlmýþtýr. Gaziantep ilinde gal oluþumuna Þehitkamil ilçesinde %42,8, Yavuzeli ve Araban ilçelerinde ise %40,0 oranýnda rastlanýrken, Karkamýþ ilçesinde gal oluþumuna rastlanmamýþtýr. Þanlýurfa ilinde ise en yaygýn gal (%66,6) Harran ovasýnýn güneyindeki Tektek daðlarý mevkiinde görülmüþ, bunu %25,6 ile Þanlýurfa-merkez ilçe takip etmiþ, Halfeti ilçesinde ise gal oluþumu düþük (%15,3) bulunmuþtur. Yapýlan çalýþmalar sonucunda Pistacia türlerinden gal oluþturan yedi yaprakbiti türü belirlenmiþtir. Bu türlerin 2'si Pistacia vera L.'da, 5'i ise P. trebinthus'da tespit edilmiþtir. Pistacia vera L.'da; Forda formicaria ve Smynthurodes betae türleri; Pistacia trebinthus'da ise Aploneura lentisci, Geoica utricularia, Baizongia pistaciae, F. marginata, Rectinasus buxtoni türleri tespit edilmiþtir. Gaziantep ve Þanlýurfa illerinde sürvey yürütülen antepfýstýðý bahçelerinde yapýlan örneklemelerde Anthocoridae, Miridae, Lygaeidae, Nabidae, Chrysopidae ve Syrphidae Familyasýndan 21 avcý tür belirlenmiþtir.

English. This study was conducted in 2010-2011 in Gaziantep and Þanlýurfa provinces to determine the species, distribution and the natural enemies of aphid species forming galls on pistachio trees. For this purpose, gall samples were taken from pistachio orchards total of 34 villages from 6 district of Gaziantep province and total of 44 villages from 5 district of Þanlýurfa provinces. In pistachio growing areas of Gaziantep, the gall formation was encountered most common at Þehitkamil (42,8%), Yavuzeli (40,0%) and Araban (40,0%) districts respectively. In the orchards of Karakamýþ district no gall forming was found. The gall forming was found most common (66,6%) in the location of Tektek mountains where high mountainous area situated at the south of Harran plain at Þanlýurfa province. Center district of Sanlýurfa came after this proportion by 25,6%. In addition to, the lowest (%15,3) distribution ratio was found at Halfeti district at Þanlýurfa province. At the results of studies, 7 aphid species were determined forming galls on Pistacia species. Two of these species were determined at Pistacia vera L. and 5 species were determined at P. trebinthus. In Pistacia vera L., Forda formicaria and Smynthurodes betae species and in P. trebinthus, Aploneura lentisci, Geoica utricularia, Baizongia pistaciae, F. marginata and Rectinasus buxtoni species were determined. The surveys carried out 21 predator species from Anthocoridae, Miridae, Lygaeidae, Nabidae, Chrysopidae and Syrphidae families were determined at each month samples at Gaziantep and Sanlýurfa.
