title: Chemical composition and insecticidal activity of the essential oil of Artemisia eriopoda against maize weevil, Sitophilus zeamais.
abstract: In our screening program for new agrochemicals from local wild plants, Artemisia eriopoda was found to possess insecticidal activities against the maize weevil, Sitophilus zeamais. The essential oil of the aerial parts of A. eriopoda was obtained by hydrodistillation and investigated by GC and GC-MS. The main components of the essential oil are germacrene D (21.6%) and eucalyptol (14.2%). The essential oil possesses fumigant toxicity against S. zeamais adults with a LC50 value of 11.5 mg/L air and also shows contact toxicity against S. zeamais adults with a LD50 value of 24.8 microg/adult, respectively.
