摘要
In our screening program for new agrochemicals from local wild plants essential oil of Artemisia vestita Wall (Asteraceae) was found to possess strong insecticidal activity against maize weevil Sitophilus zeamais Motsch Essential oil of aerial parts of A vestita was obtained from hydrodistillation and was investigated by GC and GC-MS The main components of essential oil were grandisol (40 29%) 18-cineol (14 88%) and camphor (11 37%) The essential oil of A vestita possessed strong fumigant toxicity against S zeamais adults with a LC50 value of 13 42 mg/L air The essential oil of A vestita also showed contact toxicity against S zeamais adults with a LD50 value of 50 62 mg/adult (C) 2010 Elsevier Ltd All rights reserved
