Population dynamics of the peach fruit fly Bactrocera zonata (Saunders) and Mediterranean fruit fly, Ceratitis capitata (Wiedemann) was studied for the seasonal period September-December 2020, using McPhail traps with attractants Methyl eugenol for peach fruit fly males and Trimedlure for the Mediterranean fruit fly with Chlorpyrifos (CPS) insecticide for both species. Traps were periodically sampled in citrus and peach orchards at the College of Agriculture Research Station, University of Tripoli – Libya. The rates of captive adults in traps were recorded for each orchard, with peak numbers in October during the autumn season. High significant differences were observed of both pests, months, and the overlap between them. But no significant differences were observed among citrus and peach hosts. During September-December, population density of Mediterranean fruit flies exceeded that of peach fruit flies by 27- 4.5%. The ideal recorded maximum and minimum temperatures correspond to the density peak level of trapped Peach fruit flies (2790 flies) and Mediterranean fly (3450 flies) in October, with 23.5 °C (20.5 - 27.5 °C) average temperature, and the monthly average of the ideal relative humidity 61%, rainfall 29 mm, and 9.4 hours daily sunshine. In addition, peak numbers of peach fruit flies and Mediterranean fruit flies coincided with fruit ripening at the study location. This research is considered the first of its kind in Libya, the data obtained correspond with previous studies in the Mediterranean region and adjacent countries. Seasonal observations of fruit flies will serve future planning strategies and management of these economic pests.
