PZPeixu ZhangChina West Normal University MLMin LeiChina West Normal University HLHongling LiuQilu University of Technology

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.
