Abstract :Essential oil vapors obtained by the hydrodistillation of Prangos ferulacea insert ignore into journalissuearticles values(Umbelliferae); were tested on the different stages of Ephestia kuehniella Zeller insert ignore into journalissuearticles values(Lepidoptera: Pyralidae); and egg parasitoid Trichogramma embryophagum Hartig insert ignore into journalissuearticles values(Hymenoptera: Trichogrammatidae);. Extracts of the volatile fractions from P. ferulacea were analyzed by capillary gas chromatography-mass spectrometry. The major compound of the essential oil was detected as 2,3,6-trimethyl benzaldehyde insert ignore into journalissuearticles values(66.59%); and the minor compound was heneicosane insert ignore into journalissuearticles values(0.02%);. The third instar larvae of E. kuehniella insert ignore into journalissuearticles values(LC50: 379.662 µL L-1 air and LC99: 538.755 µL L-1 air); and the pupal stage of T. embryophagum insert ignore into journalissuearticles values(LC50: 5.947 µL L-1 air and LC99: 19.568 µL L-1 air); were found to be the most tolerant stages. The essential oil was toxic to the adult stages of both the pest and its parasitoid with 100% mortality obtained after 24 h at 1.0 and 0.25 µL L-1 air, respectively. The LC50 and LC99 values of the essential oil against the egg stages of E. kuehniella and T. embryophagum were 320.372-486.839 µL L-1 air and 2.121-5.662 µL L-1 air, respectively. In general, the mortality rate increased with the increasing concentration of essential oil. The results of the study indicated that essential oil of P. ferulacea should be used as a control agent against E. kuehniella for an integrated pest management program.
