Journal Title: Haya: The Saudi Journal of Life Sciences - Year 2018, Vol 3, Issue 2
Abstract
Abstract:In order to contribute to the development of an integrated pest management strategy for stored grains, the insecticidal activity of Mentharotundifolia L. essential oil was evaluated against Sitophilusgranarius, wheat weevil. Insects and toxicity tests were carried out under laboratory conditions at a temperature of 27 ± 2 ° C and a relative humidity of 60 ± 5%, at ÇankırıKaratekin University, Yapraklı Vocational School, Department of Animal and Plant Production. The essential oil was analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS) to give 14 compounds in the essential oil of M. rotundifolia. The major component of the oil was identified as 3-Cyclopenten-1-one, 2-hydroxy-3-(3-methyl-2-butenyl)- (89,09%). M. rotundifolia essential oil has remarkable insecticidal properties. Highest contact toxicity (100%) of the oil was observed against S. granarius (1µL/insect application of 4% (v/v) oil solution in acetone, after 24 h). Highest fumigant toxicity (100%) was observed for S. granarius (10µL/10mL container application of 1% (v/v) oil solution in acetone, after 24 h). The set of knowledge elements obtained should help guide strategies for the integrated protection of the grain quality during the storage of local cereals production. Keywords:Essential oil, Mentharotundifolia,Sitophilusgranarius, contact toxicity, fumigant toxicity, stored products.
