Abstract

Fruit flies belong to family Tephritidae are notorious pests of horticultural crops in Sudan. Their signifcance is increased after the introduction of Bactrocera invadens. This study was commenced during 2007-2009 to find out species composition of fruit flies at Khartoum and Kassala, determine host ranges and asses their field response to protein hydrolaste (Nulure, Torula yeast, AFFI and GF-120) and male lures (Methyl Eugenol, Terpinyl Acetate, Culure, and Trimedlure). More than 10 species belong to 3 genera were recorded: Ceratitis capitata, C. cosyra, C. quinaria, Bactrocera invadens, Dacus ciliatus, B. cucurbitae, Dacus sp., Paradalopsis incompleta and B. longistylus and two other not identified species. Mango and guava were attacked by C. capitata, B. invadens, C. cosyra and C. quinaria. Grape fruit, orange, mandarin and banana were found infested by B. invadens. Lemon and anonna were recorded as new hosts of B. invadens at Kassala. Cucumber, water melon, musk melon were found infested by Dacus ciliatus, Dacus sp. and B. cucurbitae while Sidir (Zizyphus spina-cristi and jubajuba were infested by Paradalopsis incompleta, Usher (Calotropis procera) was attacked by B. longistylus. Ceratitis capitata, B. invadens, C. cosyra, C. quinaria, B. cucurbitae responded positively to Nulure, Torula yeast, AFFI and GF-120. B.invadens responded to Methyl Eugenol while Ceratitis capitata, C. cosyra and C. quinaria were attracted to Terpinyl Acetate and Ceratitis capitata alone was attracted to Trimedlure. Torula yeast gave better results in trapping of all fruit fly species during the consecutive seasons 2007 and 2008.
