The effect of a single blood meal on the phenotypic expression of insecticide resistance in the major malaria vector Anopheles funestus

Table 1 Mean percentage mortalities at the discriminating dosages for the susceptible An. funestus strain (FANG) and the resistant An. funestus strain (Fumoz-R).

	Dose/250 ml Bottle	Mean % Mortality	SE	n	p
FANG Unfed	2 μg	29.45%	2.57%	213	> 0.05
FANG Blood-fed	2 μg	26.31%	2.80%	216
FANG Unfed	5 μg	57.00%	2.42%	261	> 0.05
FANG Blood-fed	5 μg	51.33%	4.14%	246
Fumoz-R Unfed	100 μg	59.21%	5.01%	244	< 0.001
Fumoz-R Blood-fed	100 μg	11.37%	2.54%	245

All exposures on blood-fed individuals were carried out 4 hours post blood-feeding. (FANG: pyrethroid susceptible An. funestus, Fumoz-R: pyrethroid resistant An. funestus.)
"SE" = standard error; "n" = sample size; "p" = significance of difference between the unfed and blood-fed groups following 2 sample t-tests.
