Table 1.

The mean percentage of gravid Anopheles gambiae s.s. attracted to the test cage in the WHO-tube bioassays and to the test compartment in the airflow olfactometer bioassays

Experimental treatment	Mean percentage (%) in test (95% CI)*	Odds ratio (95% CI)	p
Response towards high humidity cage (test) in WHO-tube bioassays at 21.30
Non-fed females	50 (38-62)	1
Gravid females	71 (59-81)	2.4 (1.3-4.7)	0.018
Airflow olfactometer bioassays with gravid An. gambiae s.s. in three experimental treatments
Wet (control) vs. wet (test)	56 (48-64)	1
Dry (control) vs. dry (test)	50 (29-71)	0.8 (0.3-1.9)	0.598
Dry (control) vs. wet (test)	93 (88-96)	10.6 (5.4-20.8)	< 0.001

CI = confidence interval.
