Survival times in days of An. gambiae exposed to different nutritional regimes

Nutritional regime		N	Median	Mean	± SE	Range	Survival index	P
Glucose (6%)		300	16.0	17.1a	0.4	2.0 – 35.0	0.00*	NA
T. stans		294	12.0	13.4b	0.5	2.0 – 55.0	0.18a	0.06
S. didymobotrya		278	11.0	11.6c	0.3	2.0 – 34.0	0.30a	0.03
R. communis		293	10.0	11.4c	0.4	2.0 – 37.0	0.32a	0.01
H. patens		288	7.0	7.7d	0.3	2.0 – 32.0	0.50b	0.001
L. camara		286	6.0	7.2d	0.2	2.0 – 26.0	0.58b	<0.001
P. hysterophorus		290	4.0	4.7e	0.2	2.0 – 26.0	0.72c	<0.001
Water (-ve control)		297	3.0	3.8e	0.1	2.0 – 12.0	0.77c	<0.001
None (2nd -ve control)		296	3.0	3.0e	0.0	2.0 – 6.0	0.80c	<0.001

N is total number of mosquitoes tested

SE is Standard error of mean

Survival index: (C-T)/C [(glucose control - treatment)/glucose control] expresses the effect of each treatment on the mean survival time of mosquitoes relative to the positive control (glucose)

Means and survival index with different letter superscripts in the same column are significantly different (SNK test at α = 0.05)
