Özet: In this study conducted under laboratory and field conditions in Erzincan province in 2010-2011, the important species of leaf roller (Archips spp.) causing loss of crops and quality in the apple trees were identified, population fluctuations were appeared and biology of Archips rosana, important species, was determined. The orchards determined in the Central and Üzümlü districts of Erzincan were visited once a week and the eggs, larvae and pupae periods of pest on apple tree were determined and monitored. Pherocon-type traps were hung on the branches of apple trees in survey orchards for observing the changes of adult period. The species of leaf rollers, Archips podana (Scopoli, 1763), A. rosana (L., 1758) and Archips xylosteana (L., 1758) (Lepidoptera: Tortricidae) in the apple orchards in the Erzincan were determined. Among these three species, A. rosana was found to be more intensive and determined to be an important species. The eggs of A. rosana were hatched 295-323 days in nature and average 312 days of its life cycles were spent in period of eggs. Also, as total larvae period of A. rosana was 59-77 days, pupae period was 36-41 days. After 17-23 days from first pupae appeared the exits of adults were recorded. Archips rosana had one generation in a year under Erzincan ecological conditions in 2010 and 2011.
