Abstract
Experiments were carried out to study the effect of infestation by Macrosiphum rosae (L.) and Frankliniella occidentalis (Pergande) on the morphological characters of eight rose varieties (four local var. and four import var.).Experiments were done in El-Orman garden, Giza Governorate throughout two years (2004 and 2005). Results indicated that the all the morphological characters (colour of the flower, number of the petals per flower, the flower diameter, weight of the flower, the stem length, colour of the leaves, vase life and annual production) were reduced after infestation by the two pests. The effect of M. rosae was higher than the effect of F. occidentalis, the results also indicated that the infestation bythe two insectsconcentrated on the vascular bundles and barynshema in the tissue of the rose petals and occurs damage in these parts.
