Abstract : The population dynamics of Mediterranean fruit fly (MFF), Ceratitis capitata, and peach fruit fly (PFF), Bactrocera zonata, were studied in mango orchards at Sinuris and Ibshaway districts, Fayoum Governorate, Egypt, during 2002 and 2003. The rate of infestation in mango fruits with MFF and PFF together and separately were estimated at six locations. MFF population was significantly lower than the PFF population during the two successive seasons. Captures per trap per day (CTD) of MFF ranged from 0.09 to 0.81 fly, with a mean of 0.26 fly, and from 0.09 to 1.59 flies, with a mean of 0.57 fly, during the two successive seasons, respectively. The CTD of PFF ranged from 59.5 to 275.0 flies, with a mean of 129.49 flies, and from 21.97 to 147.32 flies, with a mean of 95.79 flies, during the two successive seasons, respectively. Total percentages of infestation with MFF and PFF together at the six locations during the 1st season ranged from 4.78 to 27.15%, with a mean of 18.20%. Percentages of infestation with MFF separately were zero (because no any MFF was emerged from incubated mango fruits), and percentages of infestation with PFF were the same as the total percentages of infestation. During the 2nd season, total percentages of infestation with MFF and PFF together ranged from 8.75 to 16.76%, with a mean of 13.17%. Percentages of infestation with MFF ranged from 0.10 to 0.34%, with a mean of 0.16%, and percentages of infestation with PFF ranged from 8.65 to 16.65%, with a mean of 13.01%.
