| Abstract | ||
| The study was conducted to determine the effect of different temperatures in the reproductive capacity of Mediterranean fruit fly Ceratitis capitata (Wiedemann) in the laboratory. The results showed that temperature highly effected on females longevity and their ages at first generation. Besides, the temperatures influenced on females production, which was highest (367.97 egg/female) at 30°C, while the productivity was 129.56 egg/female at 20°C. In addition to this, it is found that the less net replacement rate (Ro) for this insect was 11.7 individual/female/generation at 35°C, whereas the rate was 43.31 individual/ female/generation at 30°C. Furthermore, the longest mean generation time (T) was 80.4 day at 20°C and smallest mean generation time was 19.8day at 35°C. Rising temperature increased Intrinsic Rate of Increase (rm) fruit fly population reaching 0.12 adult/female/3days at 35˚C. | ||
