Fumigant activity of some plant essential oils and their consustent against to Stegobium paniceum and Lasioderma serricorne (Coleoptera:Anobidae)

Abstract

In this study, fumigant activity of essential oils obtained from five plants ( Mentha piperita (Lamiaceae), Micromeria fruticosa (Lamiaceae), Anethum graviolens (Apiaceae), Salvia officinalis (Lamiaceae) and Mentha spicata (Lamiaceae)) were tested against Stegobium paniceum and Lasioderma serricorne (Coleptera: Anobidae) in the laboratory condition . For this purpose, essential oils obtained by using Neo-Clavenger apparatus were applied at 20% (v/v) concentration, dead and live individuals were recorded at the end of 24 hours. Also, fumigant activities of plant essential oils at different temperatures (10-15-20-25-30 °C ) was determined . In addition, fumigant activities of eight essential oil components (Menton, Eugenol, Carvone, Limonene, Menthol, Diapiol, Methyl-eugenol, Linolol) were tested against S. paniceum . At the end of the study, A. graviolens and M. spicata essential oils showed the highest activity for L. serricorne with 97.63% activity and the highest activity was found in M. spicata essential oil with a mortality rate of 97.76% for S. paniceum . Among the essential oil components, Eugenol has the highest fumigant activity of with 60.79% mortality rate. These results indicate that the M. spicata essential oil and eugenol could have significant potential as fumigant in the control of L. serricorne and S. paniceum .
