  • Abstract : Mango (Mangifera indica L.) is a major horticultural fruit crop in the Sudan for local consumption and export. The total production of mango fruit in 2008 was 651,000 tons. Invasive fruit fly (Bactrocera invadens) was found in Sudan (in Sinnar and Gezira State) in 2004 as unknown species of fruit fly as introduced pest into the country. On the other hand, it was recorded in Sri Lanka and Africa and identified in 2005 (Drew et al. 2005). In recent years, B. invadens was invading rapidly and replacing the already existed species in several states of the Sudan. It has sudden and persistent outbreaks of a long time during a year. Generally, the fruit production was hampered in Sudan with continuous occurrence of the fruit flies. Temperature acts as a major mortality factor. Outside the optimum temperature range of approximately 18˚ C to 27˚ C mortality increases, and there are upper and lower lethal thresholds beyond which no individuals survive long enough to complete development (Fletcher, 1987)
