Figure 3 in Detection/Monitoring of Bactrocera latifrons (Diptera: Tephritidae): Assessing the Potential of Prospective New Lures

Figure 3. Actual and regressed change in weekly B. latifrons male catch at traps with aged lure as percentage of catch at traps baited with fresh alpha-ionol + cade oil. Fresh lure was provided weekly and aged lure was allowed to age over a 9-week period. The estimated age at which trap catch was reduced to 50% of initial fresh catch is presented, as estimated from a best fit exponential decay curve of untransformed trap catch versus weeks of aging (% of fresh B. latifrons catch = ae–bx, where a = 218.15, b = 0.286, and x = age in weeks; Bioassay 3 results).
