The effect of the feeding of Macrosiphum rosae (L.) and Chaetosiphon tetrarhodus (Walk.) on the flowering of roses

Abstract

Studies concerning the effect of the feeding of aphids Macrosiphum rosae (L.) and Chaetosiphon tetrarhodus (Walk.) on the flowering of roses were carried out in four sites in the green area of Lublin in the years 2001-2003. The studies comprised the shrubs of the park rose 'Grandhotel', the Rugosa rose, the multiflorous rose and the flower-bed roses of various cultivars. Aphids Ch. tetrarhodus dominated on Rugosa rose, while M. rosae dominated on the other roses. Aphids M. rosae and Ch. tetrarhodus, when found in greater numbers, caused deformation of the leaf blades, the shortening of shoots and petioles, as well as deformation of the flowers.
