Key Points

This research aims to explore the role of trehalase in larval development and carbohydrate management in Henosepilachna vigintioctopunctata.
Investigated the effects of RNA interference on trehalase genes
Assessed larval mortality and developmental outcomes
Utilized genetic targeting to evaluate trehalase functions
Notable increase in larval mortality following trehalase gene targeting
Significant developmental malformations observed in affected larvae
Highlighted HvTre1-1 and HvTre1-5 as effective RNAi targets for pest control

Abstract

These results provide insight into the stage-dependent roles of trehalase in maintaining carbohydrate homeostasis and chitin-associated development in this pest and highlight HvTre1-1 and HvTre1-5 as promising RNAi targets for managing H. vigintioctopunctata. © 2026 Society of Chemical Industry.
