Endocrine factors modulating vitellogenesis and oogenesis in insects: An update

Area of Science:

• Endocrinology
• Reproductive Biology
• Insect Science

Background:

• The endocrine system is crucial for insect reproduction, involving complex interactions between hormones and signaling pathways.
• Over a million insect species exhibit diverse reproductive strategies, necessitating a deep understanding of endocrine control.
• Key endocrine factors include juvenile hormone (JH), ecdysteroids, and insulin-like peptides (ILPs).

Approach:

• This review integrates recent advances in omics, gene silencing, and genome editing.
• It examines the crosstalk among individual endocrine factors.
• Focuses on the modulation of vitellogenesis and oogenesis in female insects.

Key Points:

• Juvenile hormone (JH), ecdysteroids, and insulin-like peptides (ILPs) are central to insect reproduction.
• These endocrine factors exhibit complex crosstalk, influencing target tissues and ensuring successful oogenesis.
• Advanced research techniques are accelerating the study of these intricate signaling pathways.

Conclusions:

• A comprehensive understanding of insect endocrine systems is vital for reproductive biology.
• Interactions between JH, ecdysteroids, and ILPs are critical for vitellogenesis and oogenesis.
• Future research leveraging omics and gene editing will further elucidate these pathways and their applications.
