Susceptibility of Some Stored Product Pests to Essential Oils of Dill, Celery and Wild Mint
Message:
Abstract:
Utilization of chemical pesticides has caused several problems such as raising serious concerns for human health and environmental hazards. Essential oils of aromatic plants have been proposed as safe and natural insecticides for control of insect pests. In this study, toxicity of essential oils of dill, celery and wild mint was tested against C. maculatus adults and E. kuehniella and P. interpunctella larvae. Based on chemical analysis by GC-Mass, ()-carvone (48.81%), apiol (22.58%) and limonene (12.61%) in dill. apiol (21.82%), D-limonene (21.21%) and 3-caren (11.80%) in celery and myristicin (13.35%), 3-terpinolenone (13.33%) and 2-isopropylidene cyclohexanone (9.23%) in wild mint essential oils were identified as main components. The essential oils indicated strong fumigant toxicity against all tested insect species. The LC50 values of wild mint, dill and celery essential oils against C. maculatus were 58.958, 67.769 and 94.888 μl/l, respectively. P. interpunctella larvae were more susceptible than E. kuehniella larvae and C. maculatus adults to dill essential oil. The essential oil of wild mint showed more fumigant toxicity than dill and celery essential oils against E. kuehniella larvae. P. interpunctella larvae were also more susceptible than C. maculatus adults to mint essential oil. According to the results of present study, essential oils of dill, celery and mint have good potential to be utilized as natural insecticides in management of C. maculatus, E.kuehniella and P. interpunctella.
