The effect of pheromone (methyl eugenol) dispensers on the catches of male Dacus zonatus (Saunders) in the trap was tested under field conditions. Lure injected in cotton wicks captured male flies efficiently up to nine weeks. Though the mean number of males captured during first week in traps with cotton wick dispensers was comparatively less than cork sheet, cigarette filter tip, pith of sarkanda and blotting paper but it increased during five successive weeks and thereafter decreased. However trap catches decreased from second week onward with rest of the dispensers. The results manifest that cotton wick as a dispenser for methyl eugenol proved most efficient in attracting the flies for longer duration and thus had a potential usefulness for monitoring and control of D. zonatus
