Abstract : This experiment was conducted in two seasons 2007/2008 and 2008/2009 at a mango production farm in Abyan Governorate to test the efficiency of colored pheromone traps for monitoring of fruit fly B. zonata, a pest mostly spread and damaging to mango fruits. The study included five treatments representing colored pheromone traps with pheromone methyl Eugenol, specialized for attracting male insects under study. The treatments were: Green Delta trap+pheromone+sticking material; White Delta trap+pheromone+sticking material; Open Yellow trap+pheromone+sticking material; Open reinforced Carton trap+pheromone+sticking material, and open reinforced Carton trap+sticking material only. The work was implemented during three months, from March to mid June in both seasons. The results indicted the efficiency of green Delta traps, followed by white Delta traps which are significantly different from other traps. The green Delta trap had 785 insect/trap at the end of the study and the white Delta trap had 683.3 insect/trap. The average number of fruit fly trapped by yellow trap was 480 insect/trap and 146.7 insect/trap collected by reinforced carton trap and 12.3 insect /trap in control. The result revealed a reduction in pest population in the next season compared to the first season. The green trap 383.3 on the white trap, whereas the average number of insects 209.6 insect/trap were recorded on yellow trap, and 203.0 on cartoon trap. The number of insect in the control reached 20.3 insect/trap. During the study period, the host for fruit fly was recorded. We concluded that the role of sex pheromone and trap colors attract the male fruit fly.
