All means based on 8 or 12 (Azaguié only) replicates. Indices followed by *, ** or *** are significant at the 0.05, 0.01 or 0.001 levels respectively. Cattle, human and pig odours obtained from a single ox or bull, two humans or three pigs unless indicated otherwise. Syn. Cattle = synthetic cattle odour (carbon dioxide (2 L/min), acetone (∼500 mg/h), 1-octen-3-ol (∼0.5 mg/h), 4-methylphenol (∼1 mg/h), 3-methylphenol (∼1 mg/h) and 3n-propylphenol (∼0.1 mg/h).
†: Carbon dioxide (CO2) dispensed outside. For all other experiments, carbon dioxide was dispensed inside a tent.
