摘要:
RH5849 is a benzoyl hydrazine analog which has been reported to mimic several effects of the arthropod steroid hormone ecdysone to which it is chemically totally unrelated. In adult Diptera, ecdysone is the hormone that triggers vitellogenin synthesis. We report here that RH5849, upon oral ingestion, is able to induce vitellogenin synthesis in maleDrosophila, Neobellieria, PhormiaandLucilia.This contrasts to data in the literature which showed that RH5849 could not mimic the pupariation-inducing effect of ecdysone in last instar fly larvae. RH5849 neither exerts a juvenile hormone mimicking effect nor behaves as an anti-juvenile hormone in both the Colorado potato beetle andGalleria.
