4 × 4 Latin square experiments using various combinations of odours in combination with MM-X traps. Catches of An. gambiae s.s. (Mbita strain) for 4 trap nights (200 released per night), including totals caught are shown. FO = Foot odour (from BNN). Totals in the same column not followed by the same letter are significantly different at P < 0.05.
