Volatile oils from plants of Zingiberaceae, Alpinia galangal (L.) Swartx., Zingiber officinale Rosc., Alpinia allughas Rosc., Boesenbergia pandurata Holtt., Zingiber cassumunar Roxb. And Curcuma zedoaria Rose were obtained by hydro-distillation method. Bioassays, using impregnated filter paper test, against the flour weevil (Tribolium castaneum Herbst) and the rice weevil (Sitophilus oryzae L.) were undertaken. Z. officinale and A. galangal oils caused high toxicity to rice weevil than flour weevil. The LC50 values at 48 hr were 10,543 and 13,693 ppm, respectively. This study demonstrates the potential of utilizing these oils as protectant against stored-product pests. Further study on chemical composition of these volatile oils and test under storage condition will be established.
