The aim of this work was to determination of the threshold temperature and the required degree days for development represent the fundamental base for prediction of phenology of the insect annually as well as integrated with the other methods. The time needed for 50% of individuals to achieve development from egg stage to adult stage was recorded at the following constant temperatures: 15, 20, 25, and 30 ±1C°. The results revealed that there are significant differences of development periods of Dacus frontalis at the different temperatures and hosts, the shortest period of development to adult’s stage was at the 30°C on Zucchini reached 15.207 days and the longest period was at the 15°C on Cucumber. The threshold temperatures were 11.7, 11.47 and 12.8 for crop Armenian cucumber, cucumber and Zucchini respectively. This is the first work on threshold temperature and development periods of D. frontalis.
