We studied the effect of rose shrub spatial pattern and density toward its parasitism by Diplolepis rosae gall wasps, considering host shrubs' size. There were eight sample sites on dry pastures and/or on the edges of these pastures. Our results show that high densities rose shrubs show uniform distribution, while the low densities ones appear aggregated. Gall density and prevalence are affected by host plant aggregation. Gall aggregation is inversely related with host plant aggregation. The plant architecture hypothesis regarding rose shrub size was not supported.
