Diversity of Glossina in the forest belt of Côte dʹIvoire

Collections of Glossina with a biconical trap have been made for 6 years in the forest area of Daloa in Côte dʹIvoire. Three species of Glossina have been identified in the village of Batéguédéa II as well as in the plantations and gallery forests. They are: G. palpalis, G. pallicera and G. nigrofusca. G. palpalis was predominant in the village in 1984, representing 74% of the collection, while the G. pallicera and G. nigrofusca types are more common in plantations and gallery forest. In 1987, 3 years after the first observation, G. palpalis was the most common species in each of the three biotopes. G. palpalis was even more common in 1990, following a decline in the population of G. pallicera and G. nigrofusca in the village (0.2% for G. pallicera; 0.8% for G. nigrofusca) and the plantations (0.7% for G. pallicera; 1.3% for G. nigrofusca). However, these two species were still found in small numbers in the gallery forest.
