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. Keywords: Mango, fruit fly, infestation, Sudanese zone, Mali.
Highlights
Agrosylvopastoral sector contributes around 70% of export value providing about 80% of populations’ income (Vayssières et al, 2004)
The results revealed the presence of three species: B. invadens, C. cosyra and Ceratitis ditissima of the order Diptera and Tephritidae family (Table 1)
According to the results reported by Ouédraogo et al (2010) in Burkina Faso and Keita (2015) in Mali, the emergence rate of C. cosyra is significantly higher than that of B. dorsalis in mangoes
Summary
Agrosylvopastoral sector contributes around 70% of export value providing about 80% of populations’ income (Vayssières et al, 2004). Fruit and vegetable sector play very important role in Mali socio-economic development policy (Helvetas, 2003). Among this sector, more importance has been given to mangoes either from the professional sector, government or partners for the country's development. More importance has been given to mangoes either from the professional sector, government or partners for the country's development It occupied the first position in term of fruit exportation (Helvetas, 2003). The continent of mangos origin, is the largest producer with 71% of world production followed by Africa (17%) and America (10%) (FruiTrop, 2016). Mango is produced throughout Mali with a major production of this country from Sikasso, Ségou and Koulikoro regions in addition to Bamako district (Thiam et al, 2001)
