Mosquito disease transmission and insecticide resistance

Overview

Scientific research has identified key biological mechanisms regarding mosquito-borne disease transmission and their increasing resistance to chemical controls.

Researchers at the Institute of Molecular Biology and Biotechnology (IMBB) identified genetic mechanisms, such as mutations in molecular targets and the production of enzymes that break down substances, which allow mosquitoes to develop high levels of insecticide resistance. This poses a threat to public health as mosquitoes vector diseases like malaria, dengue, and West Nile virus.

Complementary studies have explored viral transmission, finding that mosquito saliva contains a viral RNA component called sfRNA that may inhibit a host’s initial immune response. Concurrently, research on Aedes aegypti mosquitoes has provided evidence of resistance to alpha-cypermethrin, noting that certain individuals survive through the rapid activation of detoxification enzymes like beta-esterase.
