General description
Research Area: Cell Signaling
Juvenile hormone III (JH III) is the most prevalent juvenile hormone (JH) found in insects.
Juvenile hormone III (JH III) is the most prevalent juvenile hormone (JH) found in insects.
Application
Juvenile hormone III has been used to:
- study the effect of juvenile hormone on mictic (sexual) female production of the rotifer Brachionus plicatilis Muller
- study the effect of juvenile hormone on head GB19811 (putative Takeout/juvenile hormone binding protein) mRNA levels in adult honeybees
- study the effect of juvenile hormone on gonadotropic and physiological functions in bumblebee Bombus terrestris
Biochem/physiol Actions
Controls the larval metamorphosis of insects, including the retention of juvenile characteristics.
JHBPs (JH-binding proteins) protect JH (juvenile hormone) from JH esterase- and epoxide hydrolase-mediated degradation. They also help in delivering JH to target tissues.Juvenile hormones(JHs) are a group of acyclic sesquiterpenoids, and in some insect lineages, the farnesol backbone of these compounds undergoes chemical modification to produce a homologous series of hormones. JH is essential for insect development and reproduction in every aspect. It plays a key role in metamorphosis and caste determination in social insects. It modulates behavior, polyphenism, larval and adult diapause, and ovarian development. The sesquiterpenoid backbone of juvenile hormone III (JH III) is biosynthesized through the classical mevalonate (MVA) pathway in cockroaches.

The mirid bug, Cyrtorhinus lividipennis Reuter, is an important predator of rice planthoppers in Asia. In a previous study, C. lividipennis fed on gramineous weeds with brown planthopper (BPH) eggs had reduced development compared to those fed on rice with

Juvenile hormone III skipped bisepoxide (JHSB(3)), methyl (2R,3S,10R)-2,3;10,11-bisepoxyfarnesoate was recently determined as a novel juvenile hormone (JH) in a stink bug, Plautia stali. To further confirm the biological function of JHSB(3) in this insect, its juvenilizing, reproduction-stimulating and diapause-terminating activities

Most aphids show reproductive polyphenism, i.e. they alternate their reproductive modes from parthenogenesis to sexual reproduction in response to short photoperiods. Although juvenile hormone (JH) has been considered a likely candidate for regulating the transition from asexual to sexual reproduction

Diapause, a programmed developmental arrest primarily induced by seasonal environmental changes, is very common in the animal kingdom, and found in vertebrates and invertebrates alike. Diapause provides an adaptive advantage to animals, as it increases the odds of surviving adverse

Juvenile hormone (JH) controls diverse physiological and developmental events including diapause and nutrient metabolism. The focal point of endocrine regulation in adult reproductive diapause is initiated by a halt of JH synthesis. In diapausing females of the mosquito Culex pipiens
