Abstract:
Objective: To test fumigant and repellent properties of sesquiterpene-rich essential oil from Teucrium polium subsp. capitatum (L.). Methods: The fumigant toxicity test was performed at (27±1)°C, (65±5)% relative humidity, and under darkness condition and 24 h exposure time. The chemical composition of the isolated oils was examined by gas chromatography-mass spectrometry. Results: The major compounds were α-cadinol (46.2%), caryophyllene oxide (25.9%), α muurolol epi (8.1%), cadalene (3.7%) and longiverbenone (2.9%). In all cases, considerable differences in mortality of insect to essential oil vapor were observed in different concentrations and exposure times. Callosobruchus maculatus (C. maculates) (LC
