Abstract
WHAT IS ALREADY KNOWN ABOUT THIS TOPIC? Anopheles sinensis (An. sinensis) is the predominant malaria vector in China. The impact of S-methoprene on the emergence process of mosquito larvae suggests its potential as a control method for vector mosquitoes. However, the efficacy of S-methoprene in controlling An. sinensis has not yet been demonstrated. WHAT IS ADDED BY THIS REPORT? The effectiveness of S-methoprene against An. sinensis was assessed in laboratory and semi-field conditions in Yunnan Province. WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE? These results offer valuable options and guidance for utilizing S-methoprene products in malaria reimportation prevention areas within Yunnan Province.
