Özet
Essential oil obtained from the plant species Artemisia spicigera C. Koch and Helichrysum plicatum L. (Asteraceae), Mentha longifolia L., Origanum acutidens L., Rosmarinus officinalis and Salvia multicaulis Vahl (Lamiaceae) were tested for their toxicities against the larvae of Dendroctonus micans (Kugelann) (Coleoptera: Curculionidae: Scolytinae) in laboratory conditions. The results show that essential oils of A. spicigera, H. plicatum, M. longifolia, O. acutidens, R. officinalis and S. multicaulis have an insecticidal effect against the larvae of D. micans, in comparison with controls. The mortality of the larvae of D. micans increases significantly after treatment with the essential oils (P<0.01). The amounts of essential oils applied were 5 and 10 μl in each, corresponding to 38.46, and 76.92 μl/L air. The mortality rates of 1-2 larval stages of D. micans after 72 h of treatment with 5-10 μl doses of essential oils of R. officinalis (73.3%), O. acutidens (73.2%) and M. longifolia (70.8%) clearly demonstrate an insecticidal effect. M. longifolia (26.6%), A. spicigera (25.5%) and H. plicatum (24.4%) have the highest mortality rates for 3-4 larval stages.
