Title : Measuring the toxic and repellent effect of Cinnamomum zeylanicum and Elettaria cardamomum essential oils on two stored products insect pest

Abstract :

Botanical products are the best alternative to chemical insecticides to minimize the negative impact. In this work, Cinnamomum zeylancium essential oils (Laurales: Lauraceae) and Elettaria cardamomum (Zingiberales: Zingiberaceae) were evaluated to determine toxicity, repellent and detrimental effects on progeny of Sitophilus granarius (linnaques) (Coleoptera: Curculiondae) and Tribolium confusum (jacquelindu val) (Coleoptera: Tenebrionidae). Furthermore, to assess grain weight loss percentage. Chemical analysis of the testing materials was conducted using a GC-MS method to recognize the main components of the tested materials which probably had the toxic effect. The obtained results showed that, the two essential oils at all concentrations have higher repellent effect on T. confusum than S. granarius. Elettaria Cardamomum is an effective toxic and repellent agent against the two tested insects at all concentrations. Elettaria cardamomum LC50 values 2.18, 8.96 ml/kg compared to 5.15, 12.97 ml/kg for C. zeylanicum against S. granarius and T. confusum respectively. However, T. confusum is more tolerant. In addition, the two botanical oils inhibited the emerged adults and reduced the weight loss of grains. Chemical analysis of essential oils of C. zeylancium and E. cardamomum revealed that the majority of them was Cinnamaldhyde (63.13%) and a-terpinayl-acetate (47.64%) for C. zeylancium and E. cardamomum respectively.
