Eb. Dogan et Pa. Rossignol, An olfactometer for discriminating between attraction, inhibition, and repellency in mosquitoes (Diptera : Culicidae), J MED ENT, 36(6), 1999, pp. 788-793
We constructed an olfactometer that differentiates and quantifies attractio
n, inhibition, and repellency to mosquitoes. Using this device, 22 formulat
ions of various chemicals on gauze pads and 8 dilutions of DEET on skin wer
e tested. Four novel formulations were discovered acting as true repellents
. whereas DEET did not act as a true repellent but as an inhibitor.
