Flight and flight energy accumulation related to the daily rhythm of juvenile hormone titer in the wing-dimorphic cricket Velarifictorus aspersus

Yin Pang et al.

Summary: The cricket Velarifictorus aspersus exhibits two distinct life-history strategies during early adulthood - flight and reproduction. The daily rhythm of juvenile hormone (JH) titer is correlated with flight capacity and the accumulation of flight energy substances, suggesting that an elevated JH titer promotes the biosynthesis of flight energy substances, resulting in improvement of flight capacity.

The circadian clock gene (Clock) regulates photoperiodic time measurement and its downstream process determining maternal induction of embryonic diapause in a cricket

Shin G. Goto et al.

Summary: Most temperate multivoltine insects enter diapause in autumn, suppressing development or reproduction to synchronize with environmental changes. Photoperiodism and the circadian clock play important roles in this process, with the Clock gene possibly involved in both time measurement and downstream diapause-related processes.

Juvenile hormone as a causal factor for maternal regulation of diapause in a wasp

Ayumu Mukai et al.

Summary: This study found that diapause in the jewel wasp is regulated by maternal expression of the juvenile hormone (JH) and the concentration of JH in the hemolymph, which are influenced by day length.

Transcriptional Dynamics Induced by Diapause Hormone in the Silkworm, Bombyx mori

Lijuan Chen et al.

Summary: This study investigates the expression pattern of diapause hormone (DH) receptor in silkworm pupae and analyzes gene expression profile in the ovaries after DH injection. The results show that differentially expressed genes related to hormone signaling, cellular detoxification, ribosomal proteins, lipid metabolism, and epigenetic modifications are identified. The study provides valuable insights into gene expression variation during the early phase of DH release in silkworm.

Control of the insect metamorphic transition by ecdysteroid production and secretion

Xueyang Pan et al.

Summary: Ecdysteroids, a type of steroid hormones, regulate molting and metamorphosis in insects, being produced in the prothoracic gland through reduction-oxidation reactions from dietary sterols. The prothoracic gland acts as a central node integrating signals to control ecdysteroid biosynthesis and secretion, ensuring precise pulses of these hormones during metamorphosis. Recent research has focused on characterizing ecdysone biosynthesis, steroid trafficking pathways, and identifying new factors that regulate prothoracic gland function.

Expression of 20-hydroxyecdysone-related genes during gonadal development of Teleogryllus emma (Orthoptera: Gryllidae)

Wenjie Jin et al.

Summary: In this study, the characteristics of 20-hydroxyecdysone (20E)-related genes in Teleogryllus emma were assessed, revealing their roles in regulating gonadal development. The results suggest that TeERR and 20E-related genes play important roles in this process, while TeEcR appears to inhibit TeE75 expression and TeE75 inhibits HR3 expression. Hsc70 indirectly regulates the expression of other genes such as E74A, E75B, and HR3, while Hsp90 regulates Usp expression.
