Abstract: Essential oil from Artimisia scoparia leaves was assayed for repellency against adult female Aedes aegypti L. using a modified Y-tube olfactometer. Three concentrations consisting of 10, 20, and 30 Î¼l of the essential oil placed in 1x1 cm filter paper were separately assayed in the olfactometer against female A. aegypti adult mosquitoes. Results showed that 10 and 20 Î¼l A. scoparia essential oil were effective repellent against Aedes aegypti as compared to control in one-way ANOVA (Fcal 13.57>Fcrit 4.96, P, 0.004, P= 0.004219) (Fcal, 69.39>Fcrit,4.96, P= 8.25x10-6) at 0.05% confidence level. Comparison of 30 Î¼l A. scoparia essential oil repellency with a DEET-based commercial mosquito repellent showed comparable performance (fcalc 0.019
