A laboratory experiment was carried out to study the effect of four concentrations (0.5, 1.0, 2.0 and 3.0 g/l) of the alcoholic extract of the Moringa plant on whitefly and aphid’s insects. The results showed that the concentration of 3 g/l was significantly superior to the other concentrations used in the experiment, achieving percentage mortality rates of 95% in the nymph’s stage, where the account of insects decreased from 100 live insects before spraying to 5 live insects only after 72 hours of treatment with this concentration. In addition, the percentage mortality rate at the adult stage reached 91%, in which the counts of live insects decreased from 100 live insects before spraying to 9 insects after spraying with this concentration, where the rates of increase in the mortality efficiency rates reached at a concentration of 3 g/l compared to the other concentrations and at the nymph stage (13.09, 35.71, 50.79%), respectively, while the increase rates were at the nymph stage of aphids (16.25, 34.78, 47.61%), respectively. Whereas, the concentration of 0.5 g/l was the least effective in average efficiency of the concentrations used in the experiment in controlling the target insect, where it achieved a lower value of mortality rate, recording remarkable decrease, which reached at the nymphs and adults stages of whitefly and aphids insects (63, 60, 63, 61%), respectively. The chemical examinations for the detection of the plant extract content from the active compounds showed that it contains tannins, glycosides, phenols, resins, carbohydrates, saponins, alkaloids and terpenes.</p>}, number={1}, journal={Iraqi Journal of Industrial Research}, author={Taaban, Sadik K.}, year={2022}, month={Jun.}, pages={108–114} }
