Figure 2 in Release-Recapture of Sterile Male Mediterranean Fruit Flies (Diptera: Tephritidae) in Southern California

Figure 2. Capture of aerially released sterile male medflies as a function of the direction from the flight line for the four release dates. Ordinal values represent the proportion of the total captures in transect traps recorded south, north, or directly beneath the westeast oriented flight line. For a given release date, data were pooled across the different transects, different trap positions (for positions ≥ 1), and the different post-release trap servicing dates. Numbers of captures for the different release dates are given in Table 2.
