Abstract

Fumigant effects of the essential oils from Laurus nobilis L., 1753 (Laurales: Lauraceae), Mentha piperita L., 1753 and Lavandula x intermedia Emeric ex Loisel, 1828 (Lamiales: Lamiaceae) were determined against the lesser grain borer [Rhyzopertha dominica (Fabricius, 1792) (Coleoptera: Bostrichidae)], an important pest species of stored grains.
Essential oils were extracted by steam distillation by Clevenger apparatus and analyzed by capillary gas chromatography-mass spectrometry. The major compounds of the essential oils were detected as linalool (43.33%), 1,8-Cineole (57.67%) and menthone (53.51%) in Lavandula x intermedia, L. nobilis and M. piperita, respectively. The experiments were conducted in a controlled-climate chamber at 27 ± 1 °C, 50 ± 10% RH and in the dark. The fumigant effects of essential oils were determined at five concentrations (1, 5, 20, 50, and 200 μl/L air) with larval, pupal, and adult stages of R. dominica. The highest concentrations of L. nobilis and M. piperita essential oils completely killed the adults of R. dominica, while L. nobilis killed 100% of the larval stage of the pest. However, the pupal stage was less susceptible, in which the highest mortality was 49% with L. nobilis essential oil. As a result, it is considered that both L. nobilis and M. piperita essential oils have the potential to be used as effective biofumigants for stored product pests.
