Insecticidal Activity of Essential Oils of Five Aromatic Plants AgainstCallosobruchus maculatusF. (Coleoptera: Bruchidae) Under Laboratory Conditions

Abstract

The essential oils, with known effects on insects, could be an alternative method to classical insecticides. In the present study, the essential oils of Agastache foeniculum (Pursh) Kuntze, Anethum graveolens L., Cuminum cyminum L., Foeniculum vulgare Gaetner and Satureja hortensis L. were isolated by hydrodistillation method using Clevenger apparatus and their insecticidal activities determined against Callosobruchus maculatus L. adults through fumigant bioassay. A culture of C. maculatus was established on the seeds of Vigna ungiculata at 27 ± 1°C and 65 ± 5 % relative humidity. Results indicated that the essential oils had high fumigant activity on the insect. Responses were different according to the plant materials and their concentrations. The LC 50 values of essential oils from A. foeniculum, A. graveolens, C. cyminum, F. vulgare and S. hortensis against C. maculatus were 25. 476, 12.750, 11.385, 24.944 and 68.728 μL/L air, respectively. On the other hand, the toxicity of oils followed in the order: C. cyminum > A. graveolens > F. vulgare > A. foeniculum > S. hortensis. The results demonstrated that the mortality rate of all essential oils increased with concentration increase. These results suggested that the essential oils extracted from A. foeniculum, A. graveolens, C. cyminum, F. vulgare and S. hortensis can be used in the management of C. maculatus in order to decrease the detrimental effects and risk of synthetic insecticides.

A review on dill essential oil and its chief compounds as natural biocide

“…Few studies are reported in the literature about insecticidal potential of dill essential oil extracted from its different parts using mostly fumigant toxicity bioassay. The insecticidal potential of dill leaf essential oil was tested against a number of stored grain pests ( Triboliumconfusum and Callosobruchus maculatus ) using fumigant toxicity assay 50 . The authors reported that the LC 50 value for dill essential oil against C maculatus was 25.5 μL/L, and it had been found that the response of essential oil differs depending upon the concentration, whereas Khani and Basavand reported the insecticidal potential of dill seed essential oil with LC 50 value 0.54 μL/L and 143.8 μL/L against C maculatus and T confusum , respectively.…”

“…Thus, it is necessary to find alternative methods of controlling agricultural pests in order to minimize insecticide resistance and reduce the environmental damage caused by insecticides 9,10,11 Among the tactical control of M. persicae and F. schultzei, biological control can offer a sustainable solution to the management of these pests. Entomopathogenic fungi Beauveria bassiana (Bals.)…”

A pharmacological and phytochemical overview onSatureja

“…Toxicity of the essential oil vapour of S. hortensis was also evaluated against cotton whitefly, Bemisia tabaci (Genn.) (Homoptera: Aleyrodidae) and cowpea seed beetle, Callosobruchus maulatus (F.) (Aslan et al, 2004;Ebadollahi et al, 2012;Heydarzade & Moravvej, 2012;Zandi-Sohani, 2011).…”

“…), Musca domestica (L.), Sitophilus granaries (L.), S. oryzae (L.), Spodoptera littoralis (Boisduval), Tetranychus urticae (Koch), Tribolium castaneum (Herbst), and T. confusum (Jacquelin du Val.) are the other organisms of which sensitivities were tested in the presence of Satureja species (Aslan et al, 2004;Cetin et al, 2010;Ebadollahi et al, 2012;Heydarzade & Moravvej, 2012;Karpouhtsis et al, 1998;Kim et al, 2012;Maedeh et al, 2011;Pavela et al, 2008Pavela et al, , 2009;Sarac & Tunc, 1995a;Tozlu et al, 2011;Yildirim et al, 2011).…”
