Field trapping of fruit-flies Dacus spp. (Diptera: Tephritidae) using methyl eugenol over a five week period was conducted in a fruit farm at Gombaky Selangor. The results showed that traps with slit holes caught the greatest number of fruit-flies. Over 85% of the flies caught were male, Dacus dorsalis, Hendel. When different formulations of methyl eugenol; Malathion 50EC + methyl eugenol} Carbaryl 85 S + methyl eugenol, Dipterex SP 95% + methyl eugenol and distilled water -f methyl eugenol were tested at Serdang significant differences were only detected in the number of flies trapped in those traps with methyl eugenol + insecticides and those with methyl eugenol alone. The technique used was effective in controlling the fruit-flies for there was a reduction of 20% of damaged carambola fruits.
