The sex attractant (methyl eugenol) of Bactrocera zonata (Saunders) (Diptera: Tephritidae) males combined with botanical essential oils to enhance attraction ability, increase stability and/or reduce the used quantity of attractant. The present study aimed to determine stability and attractiveness of methyl eugenol mixed with lavender (Lavendula angustifolia) 
at 1:1, Eucalyptus (Eucalyptus longifolia) with 1:2 and clove (Syzygium aromaticum) at 2:1. Attraction potential and 
stability of the used combinations differently varied. Clove and lavender-methyl eugenol combinations (1:1) as well clovemethyl eugenol (2:1) nearly equal methyl eugenol alone in attraction of B. zonata males. But, Eucalyptus-methyl eugenol (1:1) and (2:1) slightly and highly more attractable for the peach fruit fly than methyl eugenol alone, respectively. In general Eucalyptus-methyl eugenol combination (2:1) enhanced attraction potential and stability of methyl eugenol as 
attractant for males of B. zonata for about 8 weeks.
