[The effect of ivermectin on the longevity of Simulium damnosum]. / Etude de l'effet de l'ivermectine sur la longévité de Simulium damnosum.

ABSTRACT

Studies on various blood-sucking arthropods have shown an increased mortality after feeding on hosts previously treated with ivermectin. We investigated in Cameroon the survival of blackflies (Simulium damnosum s.s. and S. sirbanum) fed on patients who had been treated at a dose of 150 micrograms/kg 3-13 days before the blood meal. The mortality rates were not significantly reduced when compared with those of flies fed on untreated individuals.
