Subject: what is the best way to test the repellency of a live potted plant?

Dear scientist,
I would like to know what is the best way to test the repellency of a live
potted plant. Mosquito repellency that is. I'm currently doing a research on a
plant that is sold as a mosquito repellent plant. I've searched the net (and the
local library), unfortunately I cant find any scientific proof of it's repellent
properties.  The plant mentioned is Euodia suaveolens Scheff. Its a synonim of
Euodia hortensis but with a more slender leaf. I want to test it's repellency as
a live potted plant because by doing so we'll have a sustainable and
environmentaly friendly repellent. Mind you that the smell of the plant can make
both mosquito and human dizzy :)

I'm considering a small lab experiment like a modified arm-in-cage test. I'm
trying to get the number of mosquitos down to make the counting and data
analysis easier.  Is there other methods that can be applied for this test? a
simpler one maybe?

Thank you in advance for the help.
