FIG. 2.

Cumulative mean proportion of D. melanogaster flies captured ± standard error of the mean (SEM) per 20-min period in baited traps. Means represent three replicate assay dates each, based on the performance of 50 individual flies. Infected (solid lines) and uninfected (dashed lines) flies were tested at each of three adult ages (5, 15, and 35 days). Significant differences between the performances of infected and uninfected flies for each adult age were determined by the log-rank test. *, P ≤ 0.01.
