Fumigation Activity of Plant Essential Oils against the Adults of Rhizopertha dominica
The fumigation activities of 29 plant essential oils against Rhizopertha dominica (F.)were determined by the method of treated paper fumigation. At 30 ± 1℃, relative humidity 70%, and concentration of 0.5μl/L, plant essential oils of Cinnamomum cassia, Ilex chinensis and Allium satirum had significance fumigant activities, whose corrected mortalities at exposure times of 24,36 and 72 hours all reached 98%. Mortalities from Illicium verum and Syzygium aromaticum reached 50% after 72 hours exposure. The corrected mortality of other plant essential oils was less than 10%. The effect of temperature to fumigation activities of 5 plant essential oils was tested. At 20℃ and 300℃, temperature had no significance effect on the fumigation activities of 4 plant essential oils:Cinnamomum cassia, Ilex chinensis,Allium sativum,and lllicium verum,which had significance fumigation activities.
