PZPeixu ZhangMLMin LeiHLHongling Liu

Key Points

  • The aim is to explore the effects of testosterone on reproduction in C. septempunctata.
  • Investigated the impact of testosterone sourced from aphid feeding.
  • Monitored oviposition rates and ovarian development in the ladybird species.
  • Testosterone increased oviposition and accelerated ovarian development.
  • Promoted upregulation of reproduction-related genes FDL, Vg, and VgR.

Abstract

This study suggests that testosterone naturally sourced through aphid feeding promotes oviposition, accelerates ovarian development and upregulates reproduction-related genes (FDL, Vg, VgR) in C. septempunctata. © 2026 Society of Chemical Industry.
