[Control by traps of Glossina fuscipes fuscipes for protecting livestock in Central African Republic. IV. Entomological, parasitological and zootechnical impact].

Neighteen Mbororo zebu herds were monitored to evaluate the impact of a trapping campaign against Glossina fuscipes fuscipes restricted to the watering places. This programme is part of the strategy of an integrated campaign against bovine trypanosomoses in the Central African Republic. Trapping reduces the densities of G. f. fuscipes and causes trypanosome prevalence to fall. These effects are shown by the improved hematocrit values and the reduced number of trypanocidal treatments administered. The impact on productivity is more difficult to assess over a short period; nevertheless, it seems clear from the parameters calculated.
