Our local traditional herbal and medical plant may be interduce alternative bio material alter the biology of the red spider mite Tetranychus urticae Koch. The present study was conducted to determine the direct and residual effects of the two natural plant extracts, aerial parts of Artemisia vulgaris L. and the seeds of Acacia concinna (Willd.) using soxhelt extractor, against the two spotted spider mite, Tetranychus urticae Koch, at the laboratory controlled conditions, 30±2C° and 70±5% RH. Two concentrations, 0.25% & 0.5% were utilized to study its effects on the biological aspects of T. urticae. The results confirmed the effective influence of these extracts on mite life aspects, which altered and prolonged the mite life cycle, and that reduced the number of generation/year. Moreover, the used extracts also achieved of high mortality percentages, reached 65.52% and 51.72% in pre-oviposition period and oviposition period respectively, when treated with the highest concentration of Artemisia extract. Reduction in hatchability achieved 61.11%, 57.11%, 54.11% and 52.11% for Artemisia 0.25% & 0.5% and Acacia 0.25% & 0.5% respectively.
