†The change in number of females on two blood feeders with contrasting bloodmeal quality (salted and normal blood) used as reinforcing stimuli associated with chequered and white visual patterns for bi-directional conditioning. The position of each feeder was alternated every 2 min (see methods for details). Significant results are in bold
