Table 2.

Reduced penetration of deltamethrin in resistant MRS versus susceptible Kisumu after topical application.

Treatment	Sample bodies	ng/mosquito (SD)	p-value (Wilcoxon rank)
Deltamethrin	Kisumu	0.048 (0.026)	0.002 (W = 36)
Deltamethrin	MRS	0.007 (0.001)	0.002 (W = 36)
PBO + Deltamethrin	Kisumu	0.066 (0.136)	0.006 (W = 36)
PBO + Deltamethrin	MRS	0.010 (0.023)	0.006 (W = 36)
Dicyclohexyl phthalate	Kisumu	0.073 (0.039)	0.004 (W = 36)
Dicyclohexyl phthalate	MRS	0.006 (0.002)	0.004 (W = 36)

Three biological replicate pools of 40 mosquitoes per treatment were used for chemical analysis. Deltamethrin was determined using Gas Chromatography coupled to an Electron Capture Detector (GC-ECD), PBO and dicyclohexyl phthalate by Gas Chromatography with Mass Spectrometry (GC-MS). Dicyclohexyl phthalate was used as control since it has a similar structure to deltamethrin and is not metabolised by the insects. The figures represent the means with standard deviations (SD) of the chemical contents. ng = nanogram. p-value < 0.05 indicates a significant difference according to the Wilcoxon rank sum test.
