Carbon dioxide (CO2) present in exhaled air is the most important sensory cue for female blood-feeding mosquitoes, causing activation of long-distance host-seeking flight, navigation towards the vertebrate host and, in the case of Aedes aegypti, increased sensitivity to skin odours. The CO2 detection machinery is therefore an ideal target to disrupt host seeking. Here we use electrophysiological assays to identify a volatile odorant that causes an unusual, ultra-prolonged activation of CO2… CONTINUE READING

Here we use electrophysiological assays to identify a volatile odorant that causes an unusual , ultra - prolonged activation of CO2-detecting neurons in three major disease - transmitting mosquitoes : Anopheles gambiae , Culex quinquefasciatus and A. aegypti .
Lastly , semi - field studies demonstrate that use of ultra - prolonged activators disrupts CO2-mediated hut entry behaviour of Culex mosquitoes .
