Fig 3. Relative performance of three trap batteries containing three 1m square traps versus two 1m square traps flanking a 1.5m square trap.

Bars represent the relative performance of the different trap combinations in Laminatoo, Gonycogo and data from both communities combined. Data are presented as the mean percentage of the total collection by day, normalizing for variations in the absolute number of flies collected on each day, as described in Materials and Methods. Error bars indicate the standard deviation associated with the means. The analysis from Laminatoo incorporated data collected from 18 paired trials, while the analysis from Gonycogo included data collected from 24 paired trials. Raw collection data for this study may be found in the S2 Table.
