Abstract The effects of the ingestion of some phytoecdysteroids were studied in the soft tickOrnithodoros moubata. Supernumerary moulting and malformations of first leg pairs were obtained with 22-oxo-20-hydroxyecdysone, 20-hydroxyecdysone-22-acetate, and 20-hydroxyecdysone-22-benzoate. Egg-yield was reduced with 20-hydroxyecdysone-22-acetate and carthamosterone. Finally, drying-out of eggs was observed with carthamosterone and 22-deoxy-20,26-dihydroxyecdysone. In addition, we demonstrated that there is a correlation between the number of completed gonotrophic cycles and the impossibility of inducing supernumerary moulting.
