Toxicities of pyriproxyfen, a juvenile hormone analog, were studied by topical treatment to stages of houseflies from the 3rd instar larva to pupa of a susceptible SRS strain. the toxicities gradually increased from the early stage of the 3rd instar larva to the white pupal stage. Further studies indicated that the white pupa was the most susceptible stage to the chemical and the mortality of pupae decreased sharply after the white pupal stage. Pyriproxyfen susceptibilities were compared between the 3rd instar larvae and white pupae using SRS and YPPF (a pyriproxyfen resistant strain) houseflies, white pupae of the two strains were 130 and 440 times more sensitive than the 3rd instar larvae. White pupae of YPPF houseflies were 400-fold resistant to pyriproxyfen while the 3rd instar larvae were 12,400-fold resistant. The results indicate that the white pupa is the most sensitive stage to pyriproxyfen and thus is thought to be a critical stage for the study of juvenile hormones and their analogs.
