The mango is the most universally produced fruit. In Côte-d'Ivoire, the mango official channel is threatened by fruit flies. The objective was to study the fluctuation of fruit flies population in the mango production zone in Côte-d'Ivoire. From June 2005 to September 2006 and September 2008 to August 2009, the traps using sexual attractants and an insecticide block were placed in mango orchards to capture the flies' males. In addition, various mangos ripe and those attacked by the fruit flies were collected in localities and incubated in vats in laboratory. The population fluctuation of flies' was determined through a weekly measurement of the trapped flies. Thirteen species were identifies. The fly Bactrocera invadens had the largest population across the studies zones: 97.92% in central and 86.53% in north. It was present throughout the year during mangoes seasonfrom March until August. The speciesCeratitiscosyraabounds during the maturation of the early varieties as from February until July. C. bremiiappeared from April to July. The flies abound from March in Central and Northern of Côted'Ivoire. Thus, an advanced knowledge of the fluctuation of flies' populations proves to be necessary for a durable and effective control of these pests.
