Five color traps were used to study the effect of color upon the attractiveness of Soybean stem fly Melanagromyza sojae (Zehnter),(Diptera: Agromyzidae) in  Nubaria Agriculture Research Station's farm, throughout 2015 and 2016 seasons. White, yellow, red, green, and blue sticky traps were used to estimate the attraction to suppress of M. sojae damage in soybean fields. White and yellow traps had great effect in suppressing the damage, there was increasing in seed's weight by using white and yellow traps which mean that the mass trapping of these two color was successful in controlling M. sojae, blue trap had low effect and other traps were not effective in the captivity of the adult.
