Interpretive Summary: This paper describes field experiments to measure the range of attraction of two lures on two different pest fruit fly species. These values will be of importance to those seeking to optimize fruit fly detection networks or other networks of traps. Methyl eugenol is found to be more attractive to B.dorsalis compared with trimedlure on C.capitata.
Technical Abstract: Measuring and modeling the attractiveness of semiochemical-baited traps is of significant importance to detection, delimitation and control of invasive pests. Here we describe the results of field mark-release-recapture experiments with Ceratitis capitata (Wiedemann) and Bactrocera dorsalis (Hendel) to estimate the relationship between distance from a trap baited with trimedlure and methyl eugenol, respectively, and probabilty of capture for a receptive insect. Experiments were conducted in grid of traps with a central release point at two sites on the Hawaii Island, a macadamia orchard on the east side of the island and a lava field on the west side. We find that for B.dorsalis and methyl eugenol there is a 65% probability of capture at about 36m regardless of habitat. For C.capitata, we found a 65% probability of capture at a distance of about 14m in the orchard and 7m in the lava field.
