To evaluate the effectiveness of eco-friendly treatments based on detergents classified as non-hazardous and black soap on the pest <i>Tetranychus urticae</i> Koch 1836, and their predators (<i>Euseius stipulatus</i> Athias-Henriot, 1960, <i>Typhlodromus</i> sp., <i>Phytoseiulus persimilis</i> Athias-Henriot, 1957), different treatments were applied to citrus orchards planted with Valencia late (Orange) in the Mechraa Belksiri region of Morocco (T0 = control experiment; T1 = spirodiclofen 0.5 L/Ha; T2 = 125 L/Ha (5%) of black soap; T3 = detergent; 4 L/Ha of Oni product + 2 L/Ha of Tide product). The results obtained during the whole monitoring period indicated that the three treatments used, namely spirodiclofen, black soap, and detergents, ensured a reduction in the rate of population of the pest <i>T. urticae</i> compared to the untreated plot. In the untreated plot, the average was 45.01 A± 4.90 mobile forms, while the plot treated with spirodiclofen it was only 21.10 C ± 2.71, the black soap 31.49 B ± 3.35, and in the plot treated with detergents, the average was similar to that obtained by spirodiclofen (22.90 C ± 2.18). On the predators (<i>E. stipulatus</i>, <i>P. persimilis</i>, and <i>Typhlodropmus</i> sp.), the black soap and the treatment with detergents were less harmful compared to the chemical spirodiclofen.
