Abstract

The study was carried out to study the effect of the infestation by Myzus persicae (Sulzer) (Hemiptera: Aphididae) and Tetranychus urticaeKoch (Acari: Tetranychidae) on the internal components of Aloe barbadensis (Miller), the common name Aloe Veracactus which belong to (Fam. Liliaceae). Experiments were carried out at two locations (governorates), Al-Orman garden (Giza Governorate) and The international garden (Alexandria Governorate) during season 2021.
              Obtained results showed that the infestation by M. persicae and T. urticae reduced the concentration of the internal components of Aloe Vera leaves such as Vitamin A, Vitamin C, Vitamin E, Vitamin B12, Folic acid, Amino acids,Salicylic acids, Minerals, Sugars, Lignin, Saponins and Beta carotene. And obtained results showed also that the effect of the infestation by M. persicae was higher than the effect of the infestation by T. urticae compared to control (Aloe Vera plants which did not infest by any pests) at the two tested locations.
               Statistical analysis showed that were highly significant differences between concentrations of the internal components of the infested Aloe Vera cactus plants with the two tested pests compared to the concentration of the same components in the control (non-infested cactus plants).
