Abstract

Repellency of the six essential oils (EOs), Clove (Eugenia aromaticum), Aloe (Aloe vera), Lemon (Citrus limon), Camphor (Euca-lyptus camaldulensis), Mint (Mentha spicata), Marjoram (Origanum vulgare) were evaluated against adult of the confused flour beetle Tri-bolium confusum, by allowing adults to choose between untreated filter paper halves with 1 -2g white flour or treated with different concen-trations of the oils and their mixture at three different exposure times. In individual oils ex-periments, Eucalyptus camaldulensis was found to be the best effective of repellent effi-cacy, followed by Mentha spicata and Eugenia aromaticum. Citrus limon and Aloe vera have moderate repellent efficacy. Results of combi-nation effective showed that mixtures' repel-lant activity. It has been shown that the most powerful mixture of Clove + Mint repels activ-ity against adults with Lemon + Aloe, Lemon + Marjoram, Lemon + Mint, and Mint + Aloe during the entire exposure period, while Lemon + Camphor and Camphor + Mint lost repellent activity after 24 hours.
