چکیده

Essential oils are volatile mixtures of hydrocarbons with diverse functional groups. In the current study the effect of essential oils from five medicinal plants including Zataria multiflora and Nepeta cataria (Lamiaceae), Tagetes minuta and Artemisia sieberi (Asteraceae), and Trachyspermum ammi (Apiaceae) were analyzed using GC-mass spectrometry. The toxicity of these plant essential oils against the adult stage of the cabbage aphid, Brevicoryne brassicae L. (Hemiptera: Aphididae) was studied using a fumigant assay.GC/Mass analysis revealed that the main essential oils varied between species. The most abundant components in N. cataria, Z. multiflora, T. ammi, T. minuta and A. sieberi were ۴a-α, ۷-β, ۷a-α-nepetalactone (۷۶.۸%), carvacrol (۶۲.۱%), γ-terpinene (۲۷.۱%), limonene (۱۳.۰%) and artemisia ketone (۴۸.۰%) respectively. The fumigant assays showed that all of these essential oils were toxic to B.brassicae in a dose-dependent manner. The essential oils of N. cataria at ۱۲۶, ۶۳, ۳۱, ۱۶, ۸, and ۳ μl L-۱ air caused ۹۴, ۷۶, ۵۲, ۴۶, ۳۶, and ۲۴% mortality within ۲۴ hours, respectively. The same trend was seen when essential oils of the other plants were tested against B. brassicae. These plant essential oils have great potential to be used in integrated pest management especially in greenhouses or other closed systems.
