This study was conducted on the white wormwood plant Artemisia herba alba Asso growing in Algeria. Hydrodistillation yielded an
extract of 1.5%. Chemical analysis of the essential oils, using gas chromatography-mass spectrometry (GC-MS), revealed a chemical profile
rich in diverse compounds. The primary constituents obtained were: Camphor (26.51%), Chrysanthenone (25.49%), 1,8-Cineole (8.08%),
Thujone (6.77%), and Δ-3-Carene (5.03%). The essential oil of white wormwood demonstrated high efficacy in controlling aphids, with lethal
concentration values of LC50 = 0.68 μL/ml against Myzus persicae and LC50 = 0.77 μL/ml against Aphis fabae. Statistical analysis of the data
obtained indicated significant differences between the concentrations used during the first 24 hours of exposure. The results obtained from this
study provides an effective and natural solution for aphids control. This contribution significantly promotes sustainable agriculture and
mitigates the adverse effects of chemical pesticides on both the environment and human health.
