Bioactivity of Five Essential Oils Against Bruchidius incarnatus (Bohemann, 1833)
In the world, the faba bean beetle Bruchidius incarnatus (Coleoptera: Bruchidae) is an important insect-pest, especially on faba bean Vicia faba (Leguminosae) and it can infest field crops and cause severe damage in storage. Essential oils can be an alternative method to synthetic insecticides for pest management, due to their efficiency and environmental safety. The aim of the current study was to evaluate the toxicity and repellent activity of essential oils of camphor (Eucalyptus globules), castor (Ricinus communis), cinnamon (Cinnamomum zeylanicum), clove (Syzygium aromaticum) and mustard (Brassica rapa) against B. incarnatus adults. The treatments which contained essential oils at 0.5, 1, 2 and 4% and acetone (control) were applied. All essential oils with 4% concentration repelled the B. incarnatus adult except castor oil. The percentage of repellence was higher when used essential oil of cinnamon with 2 and 4% concentration compared with other essential oils and concentrations. In residual film experiment, the cinnamon oil had the highest toxicity rate on B. incarnatus adult fallowed by clove, camphor, mustard and the lowest effect was by castor oil. Based on our results, I can conclude that essential oils of camphor, cinnamon, clove and mustard have potential for use in the integrated management of B. incarnatus adult.
