Abstract
Degree-day (DD) and thermal developmental thresholds (T0) constants for immature and mature stages of Ceratitis
capitata (Weidenmann) and Bactrocera zonata (Saunders) were estimated. The threshold of immature stages (embryonic
development, larval duration and pupal duration) which being 7.44, 5.01 and 3.18°C in C. capitata & 5.83, 3.54 and 6.65°C in B. zonata; respectively. The threshold temperature (t0) for the mature stages (pre-oviposition period) recorded 7.08 &7.23°C in C. capitata and B zonata; respectively. The (t0) of the duration generation were 8.96 &5.14°C in C. capitata and B. zonata; respectively. The temperature from 20 to 30°C was the optimum effective zone for C. capitata and B. zonata stages. The results of laboratory experments were used in a DD model for C. capitata and B. zonata stages and correlated them with field fly activity data collected from pheromone traps during two fruiting seasons 2022 and 2023. to predict the peaks of adult emergence according to the DD model patterns. we recorded four peaks each season for each species of the two fruit flies in June, July, August and September. B. zonata had higher peaks than those observed in C. capitata during the two fruiting seasons. These results helpful in timing fly activity and in IPM program pest control.
