DIVERSITY OF GLOSSINA IN THE FOREST BELT OF COTE-DIVOIRE

Collections of Glossina with a biconical trap have been made for 6 yea rs in the forest area of Daloa in Cote d'Ivoire. Three species of Glos sina have been identified in the village of Bateguedea II as well as i n the plantations and gallery forests. They are: G. palpalis, G. palli cera 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 mo re common in 1990, following a decline in the population of G. pallice ra 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. n igrofusca). However, these two species were still found in small numbe rs in the gallery forest. (C) 1997 Elsevier Science B.V.
