özet Bu araştırma ile patateslerde 6 Coccinellidae, 4 Anthocoridae, 1 Nabidae, 1 Miridae, 4 Syrphidae ve 1 Chrysopidae türü olmak üzere 17 avcıböcek türü bulunmuştur. Bunlardan Nabis pseudoferus Rem. ve Chrvsoperla camca Steph, diğer türlere oranla daha yoğun populasyon oluşturmaktadırlar. Bunlar, patateslerdeki zararlı homopter ve heteropter türlerini baskı altında tutmada etkili olmaktadırlar. Summary Predatory Insects on Patatoes in Erzurum Province-Turkey Potato is an important product of Turkey. In eastern part of Turkey, Erzurum and it's towns such as Pasinler, Oltu and some others have good ecological conditions for potato production. This study was conducted during 1986-87 in Erzurum province in order to determine the species of predator insects on potatoes Samples were taken once in a week in Erzurum, Pasinler ^ and once in 2-3 weeks in other towns by. a sweep-net during growing season At the end of the study, 6 Coccinellidae, 4 Anthocoridae, 1 Nabidae, 1 Miridae, 1 Chrysopidae and 4 Syrphidae species were found. Among these species, Nabis pseııâoferus Rem. and Chrysoperla carnea (St2). were very widespread and built up higher populations than the others. Pesticide usage is not present or very restricted in the research areas. Therefore, it ean be councluded that there seems to be a balance between the predators and pests, especially homopters and heteropters.
