The rose aphid, Macrosiphum rosae is the most important pest of the rose which causes significant economic damage annually. In order to compare four rose cultivars including Black Magic, Caramba, Noa and Good Life, and a wild rose, Nastaran, infested with rose aphid, a split-plot in time experiment was arranged in randomized complete block design layout with three replications, in Isfahan (Iran) from February 2004 to March 2005. The infestation levels of roses with the rose aphid and its seasonal fluctuations were determined by weekly sampling. Analysis of data showed that there are significant differences (P %> http://jstnar.iut.ac.ir/article-1-954-en.pdf %P 711-718 %& 711 %! %9 Research %L A-10-2-951 %+ %G eng %@ 2476-3594 %[ 2008
