†The change in number of females on two blood feeders with contrasting bloodmeal quality (salted and normal blood) used as reinforcing stimuli associated with and without Shropshire cheese smell for bi-directional conditioning was recorded. The position of each feeder was alternated every 2 min (see methods for details). Significant results are in bold (two-way test) and labelled with an asterisk (one-way test)
