摘要：Our study is about the valorization of essential oil of Dysphania ambrosio.des as botanical insecticide on Sitophilus oryzae during the storage of Triticum turgidum L. subsp. durum (Desf.) Husn. In fact, the insecticide activity of essential oil extracted by hydrodistillation from that plant has been tested by fumigation on the grains of Triticum turgidum L. subsp. durum (Desf.) Husn. after seven concentrations at the temperature beginning from 24 to 28°C and humidity of 70%. The same concentrations have been tested on S. oryzae by fumigation. During all the period of exposition the doses LC 50 and LC 99 doses have been determined and, also, the lethal times required for the death of 50% (LT 50 ) and 99% (LT 99 ) of adults exposed to different concentrations of essential oils. We notice that essential oil presents no effect on the germination of grains of Triticum turgidum L. subsp. durum (Desf.) Husn., on the contrary, it makes a very significant insecticide effect on S. oryzae.
