Detransformed mean daily catch (transformed means±SED in brackets) of <i>G. p. gambiensis</i> from traps baited with synthetic host odours.

Catch Index is the mean catch of an odour-baited trap expressed as a proportion of that from an unbaited trap. Asterisks indicate that the Catch Index differs from unity at the P<0.05 (*) or P<0.01 (**) levels of significance. Key to odours: A = acetone. O = 1-octen-3-ol; 3nP = 3-n-propylphenol; 4M = 4-methylphenol. Cells in grey show the chemicals that were used in each experiment.
