Abstract

Rosa damascena Mill belongs to Rosaceae family and is well-adaptable to environmental conditions. Our country has a long history of cultivating and breeding this plant. Although Qorveh city is regarded as the main agricultural center in Kurdistan Province, this plant is mostly bred in margins of gardens, wells, and home gardens as ornamental plants. Like other plants, Damask rose is susceptible to various pests. Therefore, based on regular visits to farms and gardens from 2009 to 2011, symptoms of drying branches, general weakness, and sudden wilting of shoots were observed. Also, light yellow, cylindrical, wizened larva, maximum 30 millimeters in length, eating inside the infected branches were observed. In fact, they had dug channels downward the branches where they themselves were located. Using available resources, however, they were keyed and as a result long-horned beetle Ospheranteria coerolescens(Col.Cerambycidae) was identified as a common and epidemic pest. Referral of infected plants to the clinics can be a good reason for this claim. Most of the using mechanical methods as well as preserving natural enemies were recommended. In time pruning of branches, a few centimeters below the drying parts, burning infected branches immediately after appearing the signs, regular watering and fertilizing, supporting natural enemies, and removing shoots were 60.9 %,13%, 9.2%, 8.3% and 8.6% respectively. From 2012 onwards, the pruned roses have not been damaged. Finally, considering integrated management seems necessary.
