Figure 4 in Release-Recapture of Sterile Male Mediterranean Fruit Flies (Diptera: Tephritidae) in Southern California

Figure 4. Capture of aerially released sterile male medflies at different trap positions for different trap servicing intervals following release (October 2011 was excluded owing to incomplete sampling). Ordinal values represent the proportion of the total captures in transect traps recorded at different positions on post-release days 1, 3, 5, and ≥ 7 d (i.e., 7, 9, and 11), where trap position 0 indicates traps beneath the flight path, and higher trap positions represent increasing distances (by increments of 268 m between adjacent positions) along transects perpendicular to the flight line. Capture data were pooled across release dates, transects, and directions; data for trap positions 13–18 were pooled and categorized as> 12. Numbers of captures for the different release dates are given in Table 2.
