Abstract
The population fluctuation of the peach fruit fly (PFF), Bactrocera zonata and the Mediterranean fruit fly (MFF), Ceratitis capitata ondifferent grape varieties (White grape variety (Sbaror), Red grape variety (Filam) and Black grape variety (Autumn royal) were studied throughout three successive seasons 2014-2016, starting from March to September and represented by catch/trap/ daily of males on three different varieties at Nubaria district. Results revealed that the population density was the most abundant during the third season in the Sbaror, Filam and autumn royal varieties. During the three seasons, the population density of MFF was more than of PFF in all varieties. Each of B. zonata and C. capitatahave one peak on Sbaror and Filamand Autumn royal varieties through period from May to July.Seasonal activity of fruit fliesrepresented by total monthly catch of males on three varieties of grape during three successive seasons recorded the highest peak of seasonal abundance on May during the third season with total monthly catch 1050.8 males/month representing 59.2% , while the total monthly catch of males during the two seasons were more in June were 160.46 and367.3 males/month representing 42.64 and 55% from total population, respectively. Results obtained of seasonal fluctuation of B. zonata and C.capitata on three varieties grapesrepresented by total numbers and percentages between varieties were more on Sbaror and Filam than autumn royal where the total population for variety through three seasons 2050.38, 547.84 and 214.79males,were recorded, respectively. The results showed that the percentage of C. capitatawas high in the third season than second and first seasons, on the other hand the percentage of B. zonata was more in the first season than second and third season in all varieties. The highest total numbers of males on' Sbaror variety was 1335.9, 467.8 and 249.67 males /seasons representing 98.73, 87.96 and 79.80% for C.C and 1.27,12.04 and 20.20% for B. zonata of total captured males, during the third, second and first seasons, respectively, while the lowest total number on Autumn royal variety was (96.4,69.4&48.99 males/season) representing (92.12,75.65& 68.09%) and (7.88, 24.35&31.91 %) for C.C and B.Z during third, second and first seasons, respectively. Statistical analysis of variance in 2014 -2016 season showed that combined effect of the weather factors to CTD revealed EV were positively significant, in Sbaror variety, the simple correlation between maximum and minimum temperatures and CTD number were high significant and significant and the percentage ofexplained variance (E.V %) were high significant and significant were 46.02 and 26.78% for during first year and second year for B. zonata.While the simple correlation between and relative humanity and CTD were positive significant for C. capitata during the third years.During 2015, the simple correlation between maximum temperatures and CTD number in Filam variety was significant during second year and the percentage of explained variance (E.V.%) were significant its 26.77 and 28.14% for B. zonata and C. capitata, respectively. In Autumn royal variety, the simple correlation between maximum and minimum temperatures and CTD number were significant and high significant during first season and the percentage of explained variance (E.V.%) were 26.75% for B. zonata, respectively.
