Bioactivity of <i>Artemisia vulgaris</i> Essential Oil and Two of Its Constituents Against the Red Flour Beetle (Coleoptera: Tenebrionidae)

Abstract Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae) is one of the most destructive pests stored products. Although there have been studies on potential use essential oils from plants in Artemisia genus as insecticides, no comprehensive bioactivity data are available efficacy vulgaris L. (Asterales: Asteraceae) oil and its chemical constituents stored-product pests. Therefore, this study, A. constituents, eugenol terpinen-4-ol, against T. were determined by contact, fumigant, repellent bioassays. Analysis contact fumigant bioassays showed that oil, eugenol, terpinen-4-ol toxicities castaneum, which has a strong killing effect larvae adults, suggesting may be main active component effects. Additionally, higher activity whereas low, indicating repellence eugenol. These results further provide relevant theoretical basis for development plant pesticides.
