Effect of innate preference in unpaired visual stimulus on learning rate in Anopheles gambiae females. The mean proportion (± 95%CIs) of females probing and feeding on the preferred feeder associated with the positive reinforcement is shown for two sets of replicates of the same experiment. The positive reinforcing stimulus of non-salted blood was associated with the innately preferred chequered visual pattern in the first set (white circles) and with the less-favoured white pattern in the second (black circles).
