Feeding success of P. papatasi sand flies feeding for 10 min on the ears of mice previously sensitized by sand fly bites at 2 and 4 weeks before the experiment (A) or on the ears of naive mice (B). Three mice were used per group; the number of flies are shown as n in each experimental group. Forty-eight hours before the experiment, the left ears of both naive and sensitized mice were exposed to 10 sand flies. Results are significantly different at P = 0.011 by a χ² test when flies fed on ears bitten 48 h before, and not significant (P = 0.27) when the flies fed on ears that were not bitten 48 h before the experiment.
