A quantitative assay for the juvenile hormones and their precursors using fluorescent tags. [PDF]
Background: The juvenile hormones (JHs) are sesquiterpenoid compounds that play a central role in insect reproduction, development and behavior. The lipophilic nature of JHs and their precursors, in conjunction with their low concentration in tissues and

Neurohormones in insect stress: A review [PDF]
The neurohormones are the master regulators of all life processes in insects and they create a strategy of stress protecting events. Neurohormones are synthesized mainly in insect brain neurosecretory neurons.

Juvenile hormone: production, regulation, current application in vector control and its future applications [PDF]
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,

Kr-h1, a Cornerstone Gene in Insect Life History
Insect life cycle is coordinated by hormones and their downstream effectors. Krüppel homolog1 (Kr-h1) is one of the crucial effectors which mediates the actions of the two critical hormones of insects, the juvenile hormone (JH) and 20-hydroxyecdysone ...

Juvenile Hormone Induction of Esterases: A Mechanism for the Regulation of Juvenile Hormone Titer [PDF]
Within a few hours after injection of juvenile hormone into Hyalophora gloveri pupae, several fast-migrating carboxylesterases (EC 3.1.1.1) that are sensitive to di iso propylfluorophosphate appear in the hemolymph.

Structure Determination of a Natural Juvenile Hormone Isolated from a Heteropteran Insect
Juvenile hormone (JH), which occurs in several forms in different insects, is one of the most important insect hormones. The structure of JH in Heteroptera has not been elucidated until recently, although insects in this suborder have long been used as ...
