Survival of An. gambiae females with constant daily access to water (solid line) or access to water restricted to 16 h per day (dashed line) during the 7-day hydric stress experiment. Separate statistical tests were conducted on female survival during the first (day 0 - mid-day 4) and second (mid-day 4 to day 7) halves of the experiment revealing a strong interaction between the stage of the experiment and the effect of hydric stress. Level of significance are P < 0.05 *, P < 0.005 **, P < 0.001 ***.
