This experiment was carried out in Shobrapeel (El- Santa), Gharbia governorate on peach orchard. From this orchard were chosen four feddans, two were cleaned from different growing weeds during the season and the other two feddans were with weeds. The seasonal population abundance of The Mediterranean fruit fly (MFF) adult males was the highest on peach orchards with weeds 35.6 and 70.3 with an average of 54.0 ± 5.6 indiv./trap/week during the first season (2017). In addition,  during the second season (2018), the seasonal population abundance of The Mediterranean fruit fly (MFF) adult males was the highest on peach orchards with weeds 92.8 and 121.0 with an average of 104.7± 5.7 indiv./trap/week.The seasonal population abundance of The peach fruit fly (PFF) adult males was the highest on peach orchards with weeds and ranged between 19.2 and 37.8 with an average of 30. 6 ± 5.9 indiv./trap/week during the first season 2017. During the second season (2018), the seasonal population abundance of The peach fruit fly (PFF) adult males was the highest on peach orchards with weeds and ranged between 30.7 and 81.2 with an average of 55.8± 7.7 indiv./trap/week. Statistical analysis revealed that there was a significant difference between peach orchards with and without weeds during the two seasons according to the means of the insect adult males.
