بررسی میزان آلودگی ژنوتیپ های مختلف گل محمدی Rosa damascene Mill) (به آفات مهم آن دراستان آذربایجان غربی

Rosa damascena Mill. is one of the most important medicinal plants that used its ooze, distillates and oil. Activity of various pests causes damage to ornamental and medicinal plant, annually. During the 2010-2013 years, contamination 36 genotypes of R. damascena were evaluated to important pest in the Urmia, West-Azarbaijan province. Field studies were carried out in damask rose in Saatlo research station of pine, Urmia. The experiment was conducted as a randomized complete block design with 36 treatments and 3 replications.
The number of insects on different genotypes of R. damascena was one of the measured traits.The results showed that there was a significant difference between genotypes in terms of density of of Macrosiphum rosa L., Edwardsiana rosae L., Allantus viennensis Schr. and Ardis brunniventris.
. Mean comparison showed that the least activity of Macrosiphum rosa L. on 12, 40, 22 and 16 genotypes originated from Zanjan, Isfahan8, Kohkluye and Fars1. Allantus viennensis Schr. larvae were another important factor causing damage in this region. Comparison of results showed the lowest density on 25 and 40 genotypes originated from Gilan and Isfahan and highest density on genotype No. 19, originated from Kordestan. Also about Ardis brunniventris Hadting the lowest contamination has been accessed . on 29, 13, 14, 17, 18, 30 and 7 genotypes originated from Hormzgan, Semnan1, Semnan2, Fars2, Gazvin, Hamadan and Tehran.
