Abstract :Experiments were conducted to investigate the biological effects of essential oils from basil insert ignore into journalissuearticles values( Ocimum basilicum L.);, paprika insert ignore into journalissuearticles values( Capsicum annuum L.);, peppermint insert ignore into journalissuearticles values( Mentha x piperita L.); and rosemary insert ignore into journalissuearticles values( Rosmarinus officinalis L.); on the different stages of Ephestia kuehniella Zeller insert ignore into journalissuearticles values(Lepidoptera: Pyralidae);. Essential oils were obtained by Clevenger-type water distillation and analyzed by capillary gas chromatography-mass spectrometry. The doses of the essential oils applied were 0.1, 1, 5, 10, 20, 50 and 100 μl L -1 air. The major compounds of the essential oils were detected as linalool insert ignore into journalissuearticles values(63.1%);, capsaicin insert ignore into journalissuearticles values(35.4%);, menthol insert ignore into journalissuearticles values(28.3%); and cineole insert ignore into journalissuearticles values(25.7%);, in basil, paprika, peppermint, and rosemary oils, respectively. The essential oil of paprika caused the highest mortality of first instar larvae of E. kuehniella at a dose of 5 μl L -1 air after 24 h exposure . Among the tested different stages, larvae of E. kuehniella were the most tolerant of essential. Basil, paprika, peppermint and rosemary oils exhibited toxicity to adult stages of E. kuehniella with 100% mortality obtained after 24 h at dose of 100, 5, 20 and 10 µl L -1 air, respectively. Increasing the doses of essential oils resulted in increased toxicity to all stages of E. kuehniella. In conclusion , the four plants essential oils tested in this study have potential for use in the management of the stored-product pest, E. kuehniella .
