Juvenile hormone III plays a major role in regulating feeding and reproduction in the adult cat flea, Ctenocephalides felis (Bouché). Both blood consumption and egg production increased in a dose-dependent manner up to a maximum at 1,250 ppm when fl

The activity of pyriproxyfen in the blood diet was investigated for its efficacy against adult, egg, and larval stages of the cat flea, Ctenocephalides felis (Bouché). Adult fleas were housed in plastic cages and fed treated bovine blood using an ar

In the last larval instar of Lepidoptera, ecdysteroid in the absence of juvenile hormone (JH) is believed to cause the shift from larval to pupal development. In Manduca sexta, tissues such as the Verson's gland and crochet epidermis become pupally c

In the tobacco hornworm (Manduca sexta), vitellogenin (Vg), the major yolk protein precursor, and its mRNA are first detectable in the prepupal stage; and production of both can be enhanced by methoprene, a juvenile hormone (JH) analog. Competence to

The role of Juvenile Hormone (JH) during reproductive development and diapause was investigated in the boll weevil, Anthonomus grandis Boheman (Coleoptera: Curculionidae). JH sythesized by corpora allata (CA) in vitro of A.grandis was identified as J

In Manduca sexta , larval-larval molting of the IVth instar ensues in response to a large pulse of ecdysteroid. Ecdysone release by the prothoracic glands (PG), in turn, is stimulated by prothoracicotropic hormone (PTTH) from the brain. We show that

The stage at which corpora allata (CA) of Manduca sexta regain the capability for juvenile hormone (JH) biosynthesis during adult development was determined by a transplantation assay and in vitro experiments with CA of adults and pharate adult stage

Denaturing electrophoresis of hemolymph from prepupae of M. sexta showed trace amounts of polypeptides with mobilities corresponding to those of vitellogenin (Vg) apoproteins from adult females. Absence of the polypeptides in allatectomized insects s

During the last larval stage, corpora allata (CA) of Manduca sexta are inactivated by a factor from the brain. Apparently the same factor (allatinhibin, Al) is secreted by day 4 Vth instar brains kept overnight in Grace's medium. Al is rapidly inacti
