Implications of successive blood feeding on Wolbachia-mediated dengue virus inhibition in Aedes aegypti mosquitoes - Nature Communications Dengue virus transmission by Ae. aegypti mosquitoes poses a significant public health threat, necessitating innovative control strategies. Here, the authors demonstrate that, while successive blood feeding increases earlier dengue virus dissemination, the inhibitory effects of Wolbachia remain strong, highlighting Wolbachia’s potential to disrupt dengue transmission under natural feeding conditions.
