28 de sept. de 2021 · Here, we describe a phenotype associated with mutations in the Drosophila JH receptor genes, Met and Gce: the accumulation of mature eggs with reduced egg length in the ovary. JH signaling is mainly activated in ovarian muscle cells and induces laminin gene expression in these cells.
18 de jun. de 2018 · Since it was first postulated by Wigglesworth in 1934, juvenile hormone (JH) is considered a status quo hormone in insects because it prevents metamorphosis that is initiated by the molting hormone 20-hydroxyecdysone (20E).
27 de oct. de 2020 · Juvenile hormone (JH) is an insect-specific hormone that suppresses precocious metamorphosis during the larval stage 6, and which has different chemical structures in different insects.
1 de ene. de 1996 · Among animal hormones, juvenile hormone (JH) is distinctive because of its unique structure and the diversity of its effects on insect development and reproduction. This chapter reviews the actions of JH on the fat body, gonads, accessory glands, muscle, and nervous system of adult insects.
Physico-chemical analysis of juvenile hormones (JHs) of Spodoptera littoralis revealed highest quantities in the second half of embryonic development and in newly hatched 1st instar larvae. At these stages, mostly JH II, JH I and little JH III were found, while in later stages only JH II and JH III were found.
1 de sept. de 2021 · Juvenile hormone is an exclusive hormone found in insects which involves regulating various insect physiology. A total of eight juvenile hormones have been identified in insects which include JH 0, JH I, JH II, JH III, 4-methyl JH I (Iso- JH 0), JHB III, JHSB III, and MF.
1 de ene. de 2012 · The juvenile hormones, a family of acyclic sesquiterpenoids, are essential to insect development and reproduction. This family of hormones has been extensively studied because of its central role in regulating development and value as an insect pest control agent.
