Population fluctuation of Mediterranean-fruit-fly, Ceratitis capitata (Wiedemann) on different fruit varieties (three-varieties); mango, pomegranate and navel-orange were studied in seasons 2021/2022 at Borg El-Arab, Alexandria. C. capitata has two-peaks on mid-July and beginning of third-week of August for mango. In pomegranate-variety there were two-peaks at third-week of August and second-peak at end-September. Whereas, navel-orange varieties found one-peak at third-week of October recorded of two-tested seasons, respectively. Statistically analysis showed, weather factors and fruits ripping-stage were highly-significant differences (73.4 and 73.9%), (69.6 and 72.2%) and (82.9 and 80.7%) on C. capitata population in tested-varieties during two-season compared-with different weather factors. Simple-correlation on second season 2022 between maximum-temperature and CTD on C. capitata was highly significant differences in mango tested. Whereas pomegranate-variety, was insignificant between max-temperature and CTD of C. capitata during two-seasons, in navel-orange was negative-insignificant during two-seasons. Minimum-temperatures and CTD-number of C. capitata were insignificant during two-seasons for mango-variety. In pomegranate were in-significant during two-seasons. While were negative-insignificant for navel-orange. Simple-correlation on two-seasons between relative-humidity for fruit-varieties were highly-significant except mango in first-season was insignificant. Statistical-analysis for three-varieties and different inspections during two-seasons, showed, first-season was highly-significant more-than second-season. Regarding mango-varieties was high more-than pomegranate and navel-orange were mean of mango (5.64) while, no-difference between pomegranate and navel-orange means were (3.45 and 4.04), respectively. Regarding varieties in two-seasons, mango was high more-than navel-orange and pomegranate (132.7 & 93.2) for mango; (101.1 & 68.7) for navel-orange and (78.3 & 53.1) for pomegranate in two-seasons.
