Glossina palpalis palpalis attractiveness testing towards humans and pigs in the area of Daloa in Côte d’lvoire

Abstract

Trapping experiments on Glossina palpalis palpalis were performed using humans and pigs as baits in the village of Noumousséria II (Daloa forest area, Côte d’ivoire). The results show that: 1) the insect population collected with pig-baited traps was 2.4-fold larger than that with human-baited traps; 2) the percentage of females captured with pig-baited traps was higher (76.16 %) than that of males, while no significant difference between the two sexes appeared with human-baited traps; 3) seasonal variations affected pig-baited traps more than human-baited traps. Qualitative analyses revealed that Glossina sampled from pigs were similar to those obtained with biconic traps. Despite the low number of dye-marked Glossina recaptured, it seems that tsetse flies are more attracted to pigs (12 tsetse flics) than to humans (none).
