Biomolecules, 2021 Currently (2020), Africa and Asia are experiencing the worst desert locust (Schistocerca gregaria) plague in decades. Exceptionally high rainfall in different regions caused favorable environmental conditions for very successful reproduction and ...

European Journal of Entomology, 2010 In the present study the hypothesis that there is a feedback between juvenile hormone and adipokinetic hormones (AKHs) was investigated by topical application of the juvenoid methoprene on 9-day-old adult males of the firebug Pyrrhocoris apterus.

Insect juvenile hormone: from "status quo" to high society
Brazilian Journal of Medical and Biological Research, 2000 Juvenile hormone (JH) exerts pleiotropic functions during insect life cycles. The regulation of JH biosynthesis by neuropeptides and biogenic amines, as well as the transport of JH by specific binding proteins is now well understood.

European Journal of Entomology, 2002 A radiochemical assay (RCA) has been used for the measurement of juvenile hormone (JH) synthesis in vitro by corpora allata (CA) from the Eri silkworm, Samia cynthia ricini.

Juvenile hormone-receptor complex acts on mcm4 and mcm7 to promote polyploidy and vitellogenesis in the migratory locust. [PDF]
PLoS Genetics, 2014 Juvenile hormone (JH), a sesquiterpenoid produced by the corpora allata, coordinates insect growth, metamorphosis, and reproduction. While JH action for the repression of larval metamorphosis has been well studied, the molecular basis of JH in promoting ...

On the corpora allata of dipterous insects. II [PDF]
Proceedings of the Royal Society of London. Series B - Biological Sciences, 1938 Abstract In an earlier paper (Burtt 1937) it was suggested, on morphological and histological evidence, that Weismann’s ring in the larva of Calliphora represents the modified corpora allata. Fraenkel (1935) had previously found that pupation in Calliphora is induced by a hormone which is secreted in the region of the central nervous ...

Identification and function of ETH receptor networks in the silkworm Bombyx mori
Scientific Reports, 2021 Insect ecdysis triggering hormones (ETHs) released from endocrine Inka cells act on specific neurons in the central nervous system (CNS) to activate the ecdysis sequence.

Journal of Applied Entomology, EarlyView.ABSTRACT Gryllodes sigillatus is an increasingly important species in edible insect production, yet the optimal rearing density for this species under commercial conditions remains poorly defined. This study evaluated the effects of five rearing densities (1.5, 2, 2.5, 3 and 4 mL of newly hatched nymphs, corresponding to approximately 0.144–0.385 ...

Starvation increases insulin sensitivity and reduces juvenile hormone synthesis in mosquitoes. [PDF]
PLoS ONE, 2014 The interactions between the insulin signaling pathway (ISP) and juvenile hormone (JH) controlling reproductive trade-offs are well documented in insects.

Molecular Ecology, Volume 35, Issue 11, June 2026.ABSTRACT Division of labour in reproduction and in task performance are two hallmarks of insect societies. Bumble bees and honey bees are both classified as eusocial, but differ in the social organization of their colonies and in the hormonal regulation of division of labour.
