Competitive testing of two BGS or MM-X traps baited with A: foot odour (worn nylon sock in central tube) + CO₂(500 ml/min) or B: foot odour + lemongrass (1 g brushed leaves) during 4 nights each, 200 An. gambiae s.s. females released per night.
Expt. A	Day	BGS foot odour + CO₂	BGS foot odour	MM-X foot odour + CO₂	MM-X foot odour

	1	109	64	102	22
	2	100	84	98	16
	3	77	57	58	25
	4	90	75	64	24
	Position	exp(B) = 1.409, P = 0.032		exp(B) = 0.701, P = 0.218
	Treatment	exp(B) = 0.714, P = 0.051		exp(B) = 0.422, P < 0.001
Expt. B	Day	BGS foot odour + lemongrass	BGS foot odour + grass	MM-X foot odour + lemongrass	MM-X foot odour + grass
	1	72	78	14	34
	2	37	65	34	50
	3	53	68	33	40
	4	32	108	24	42
	Position	exp(B) = 0.488, P < 0.001		exp(B) = 2.380, P < 0.01
