The accessory sex glands as the repository for juvenile hormone in male cecropia moths.
نویسندگان
چکیده
Gas chromatographic determinations, bioassays, and radio-labelling experiments show that the juvenile hormone in adult male Hyalophora cecropia is accumulated exclusively in the accessory sex glands. Moths do not store measurable quantities of juvenile hormone if their accessory sex glands are removed shortly after adult eclosion.

On the Specificity of Juvenile Hormone Biosynthesis in the Male Cecropia Moth *
The accessory sex glands (ASG) of adult male Cecropia contain an enzyme that methylates juvenile hormone acids (JH-acids) in the presence of S-adenosyl-L-methionine (SAM). The methyltransferase is highly specific. The reaction rates decrease in the order JH-I-acid, JH-II-acid and JH-III-acid; in each case the natural enantiomer is esterified predominantly. Methyltrans ferase activity with the ...
متن کاملActivity of juvenile hormone acid in brainless, allatectomized diapausing cecropia pupae.
Pupal diapause in the cecropia silkmoth is terminated by activation of the prothoracic glands. Implantation of adult male cecropia corpora allata or injection of juvenile hormone-I (JH-I) or juvenile hormone-I acid (JH-I acid) causes initiation of development in debrained, allatectomized diapausing pupae. The subsequent development results in formation of second pupae or pupal-adult intermediat...
متن کاملTolnidamine-Induced Changes in the Testis, Sperm Count, Fertility and Accessory Sex Glands of the Laboratory Mouse
Background Tolnidamine-induced changes have been reported earlier on spermatogenesis, fertility and sperm count in rat, rabbit and langur monkey. The aim of this study is to assess the response of these aspects to tolnidamine in the laboratory mouse. MaterialsAndMethods Adult male mice (12-14 weeks old) of Parkes (P) strain were used in the present study. All the animals were divided into five ...
متن کاملOntogenic development of digestive accessory glands in larval and juvenile Vimba bream, Vimba vimba (Pallas, 1814)
The current study investigated histological development and histochemistry of digestive accessory glands of Vimba bream Vimba vimba from hatching through 60th day after hatching (DAH). The samples were randomly taken from day 1 (hatching) until the full absorption of the yolk sac at day 7 and the day after that, then with 2, 5, and 10 days intervals until 60 DAH. The development of the digestiv...
متن کاملEffect of farnesyl methyl ether on reproductive physiology in the cockroach, Byrsotria fumigata (Guérin).
Farnesyl methyl ether (F M E ), chemically related with the juvenile hormone from cecropia o i l1, is a po tent corpus allatum hormone analogue for many in sects 2~ 4. It is not only able to prevent imaginal de velopment; it also stimulates the maturation of oocytes in the adults of some 3> 5 but not all insects 6. Barth 7 has shown that sex pheromone production by females of Byrsotria fumig...
