Figure 2. Detransformed daily trapping rates for G. swynnertoni by unbaited and POCA-baited visual devices.

trap pyramidal trap, target 1.5 m² target, leg panel local panels (0.47 m² Tanzania, 0.32 m² Kenya), std standard phthalogen blue, turq turquoise blue, blue pl blue-painted plastic (0.45 m²), unbaited no baits, baited baited with POCA, dtr. mean detransformed mean. POCA is a 1∶4∶8 mixture of 3-n-propylphenol (P), 1-octen-3-ol (O), and p-cresol (C) released from a polyethylene sachet and acetone (A) released from a bottle. The limits of the boxes indicate the twenty-fifth and seventy-fifth percentiles; the solid line in the box is the median; the capped bars indicate the tenth and the ninetieth percentiles, and data points outside these limits are plotted as circles.
