Engineered Gut Symbiotic Bacterium-Mediated RNAi for Effective Control of Anopheles Mosquito LarvaeJ. J. Ding, C. L. Cui, G. D. Wang, G. Wei, L. Bai, Y. F. Li, P. L. Sun, L. Dong, Z. C. Liu, J. Q. Yun, F. Li, K. Li, L. He and S. B. Wang, Microbiology Spectrum, 2023.![]() Anopheles mosquitoes are the primary vectors for the transmission of malaria parasites, which poses a devastating burden on global public health and welfare. The recent invasion of Anopheles stephensi in Africa has made malaria eradication more challenging due to its outdoor ...

Holobiont perspectives on tripartite interactions among microbiota, mosquitoes, and pathogensR. Zheng, Q. Wang, R. Wu, P. N. Paradkar, A. A. Hoffmann and G. H. Wang, ISME, 2023.![]() Mosquito-borne diseases like dengue and malaria cause a significant global health burden. Unfortunately, current insecticides and environmental control strategies aimed at the vectors of these diseases are only moderately effective in decreasing disease burden. Understanding and ...

An evaluation of fusion partner proteins for paratransgenesis in Asaia bogorensisC. Grogan, M. Bennett and D. J. Lampe, Plos One, 17:18. 2022.![]() Mosquitoes transmit many pathogens responsible for human diseases, such as malaria which is caused by parasites in the genus Plasmodium. Current strategies to control vector-transmitted diseases are increasingly undermined by mosquito and pathogen resistance, so additional ...
