Single dose (100 µl/L) of plant essential oils were initially tested on adult stage of <em>A. obtectus </em>. The greatest fumigant toxicity against <em>A. obtectus </em> was seen with <em>F. vulgare </em>essential oil, followed by <em>T. spicata </em>and <em>L. stoechas </em>essential oils. In the dose response bioassays with <em>F. vulgare </em>, <em>T. spicata </em> and <em>L. stoechas </em>, the calculated LC <sub>50 </sub> values were 22,3 µl/L, 32,4 µl/L and 46,3 µl/L respectively. The main components of plant essential oils of three plants showing high response were determined by GC-MS analysis. <em>F. vulgare </em> essential oil’s main components were anisole (79%) and L-Fenchone (13%). <em>T. spicata </em> and <em>L. stoechas </em> contain L-Fenchone (55%, 57%), Camphor (24%, 24%) and Eucalyptol (13%, 13%) respectively. Main components L-Fenchone and Camphor caused about 100% mortality at 80 µl/L dose in 48 hours. The results indicate that <em>F. vulgare </em>essential oil or its components may have a potential in controlling of <em>A. obtectus </em>. <em> </em> </p>}, number={1}, publisher={Türkiye Entomoloji Derneği}
