An international research team has identified a critical odorant receptor in mosquitoes that allows them to detect and avoid a natural repellent compound, according to a statement released by the Hebrew University of Jerusalem on Tuesday. This discovery could revolutionize mosquito control strategies, particularly in Asia, where mosquito-borne diseases like dengue and malaria remain pressing public health challenges.
The study highlights the receptor’s role in helping mosquitoes circumvent existing repellents, offering scientists a new target for developing more effective and environmentally sustainable alternatives. Researchers emphasized that this breakthrough could reduce reliance on chemical insecticides, aligning with global efforts to promote ecological balance.
Dr. Li Wei, a Beijing-based entomologist unaffiliated with the study, noted, “Understanding mosquito sensory mechanisms is key to curbing disease transmission. This finding opens pathways for innovations that benefit both public health and ecosystems.” The research team included experts from institutions in Israel, Japan, and Singapore, reflecting Asia’s growing role in collaborative scientific advancements.
With climate change expanding mosquito habitats, the timing of this discovery is critical. Health authorities across Southeast Asia have reported rising dengue cases in 2026, underscoring the urgency for improved preventive measures.
