A survey of Anopheles species composition and insecticide resistance on the island of Bubaque, Bijagos Archipelago, Guinea-Bissau

Table 3 kdr-w genotypes (R is the 1014F kdr resistant allele and S is the wild-type allele) of female An. gambiae s.l. mosquitoes phenotypically resistant and susceptible in CDC-bottle bioassays using α-cypermethrin

	Phenotype	Genotype			R allele frequency	Odds ratio (95% CI)
	Phenotype	SS	RS	RR	R allele frequency	Odds ratio (95% CI)
An. gambiae	Resistant	2	7	5	0.607	30 (3.56, 252.97)
An. gambiae	Susceptible	10	4	0	0.083	30 (3.56, 252.97)
An. gamb/col hybrid	Resistant	1	3	3	0.642	24 (1.74, 330.8)
An. gamb/col hybrid	Susceptible	8	2	0	0.100	24 (1.74, 330.8)

Numbers show total females of each genotype. Odds ratios (with 95% confidence intervals) were calculated to indicate the odds of an individual being resistant if it carried a kdr-w copy
