Abstract. The fruit fly (Diptera: Tephritidae) is one of the plant-disturbing organisms in red
chilies. This pest can causes yield losses that varies between 30 and 100%. An effective and
environmentally friendly technique which could be applied to control this pest is the use of
methyl eugenol attractant combined with the colour of the trap. A research was carried out in
Tangkit Village, Sungai Gelam Subdistrict, Muaro Jambi District to test the effectiveness of a
combination of several attractant doses of methyl eugenol and colour traps on the amount of
fruit flies (Diptera: Tephritidae) trapped in the red chili plantations. This study used a split
plot design. Methyl eugenol dose as first factor consisting of two level namely 0,5 ml, 1,5
ml., and trap colour as second factor consisting of three level namely red, yellow, blue so that
there were six treatment combinations with 4 replications. The research result showed that
the amount of fruit flies trapped in trap with methyl eugenol dose 1.5 ml and yellow colour
more than those of in other treatment combinations. Although the attractant dose of methyl
eugenol has a stronger effect than the colour of trap in trapping fruit flies, this study showed
that effective control of fruit flies (Diptera: Tephritidae) must involve both elements.
