Abstract : Fruit flies (Diptera: Tephritidae) are the most serious insect pests of fruits and vegetables in tropical and subtropical areas of the world. They destroy horticultural produce by oviposting in fresh plant tissues while still on the plant and causing serious economic losses. The present study was carried out in River Nile State, particularly in Shendi, Elzidab, Elkitiab and Elbawga to identify the different species of fruit flies in the River Nile State, to determine the host range of the identified fruit species and to detect the efficiency of fruit fly attractants: Methyl Eugenol and protein hydrolysate. The field Monitoring of Tephritid fruit fly species using Nulure as a food attractant in four locations Shendi, Elzidab, Elkitiab and Elbawga in the River Nile State revealed the presence of three species namely Asian fruit fly, Bactrocera invadens, Mango fruit fly, Ceratitis cosyra and Mediterranean fruit fly, Ceratitis capitata. The host range study revealed that, 2 different plant species (mango and guava) out of the 10 collected from Shendi, Elzidab, Elkitiab and Elbawga were found to harbor B. invadens, C. cosyra and C. capitata. The mean number of insect catches per trap per day indicated that there was a significant difference between Lynnfield trap baited with methyl eugenol (42.3) and Lynnfield trap baited with local bait protein hydrolysate (0.6). Lynn filed trap baited with methyl eugenol was more efficient and attracts large number of fruit flies than a local bait trap. Methyl eugenol proved to be more effective in attracting the male of Bactrocera invadens.
