Abstract

Mali has a potential for mango production across the country. However, this plant is facing phytosanitary problems mainly related to fruit flies. The study was conducted to evaluate the infestation rate of fruit flies on mango varieties in Sudanese zone of Mali (Kati). Stung mangoes were weekly collected from three sites. Fruits were weighted and placed inside plastic bags containing sand to the monitor larva infestation under semi-natural conditions within of the laboratory. Bactrocera dorsalis and Ceratitis cosyra were the two species identified from all sites with an average of 22.88 and 23.32 fruit flies, respectively. C. cosyra appreciated mango varieties such as Valencia, Amelie, Kent, Davis Haden and Keitt whilst B. dorsalis preferred Keitt, Brooks, Kent and Smith varieties. No correlation was found between mangoes weight and the number of emerged flies in addition to lack of sex predominance based on fruit’ fly species. The infestation rate varies according to the variety of mangoes.
