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.

Implication

Study shows testosterone enhances oviposition and ovarian development in ladybirds, indicating ecological impacts.

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.
