Many countries operate trapping programs to detect invasions of pestiferous fruit fly species (Diptera:Tephritidae). Surveillance relies heavily on traps baited with male lures, which, while highly attractive, havelimited effectiveness, because (i) they are sex-specific and (ii) males of some species do not respond to the lurescurrently in use. For these reasons, detection programs also include food-baited traps that are neither sex- norspecies-specific. Compared to male lure-baited traps, however, few studies have measured the attractiveness offood-based traps. The present study describes a mark-release-recapture study conducted in a fruit orchard inHawaii that measured the attractiveness of a liquid protein hydrolysate-based (torula yeast/borax slurry) trap toadults of the melon fly Zeugodacus cucurbitae (Coquillett). Multiple release points were used at varying distancesfrom a single, central trap to generate estimates of distance-dependent capture probabilities. The potential influencesof sex and pre-release diet on capture probability were also examined. Flies were released at 14 d of ageand were maintained on one of four dietary regimes that offered a protein hydrolysate-rich diet for varyingintervals (i.e., 0, 3, 7, or 14 d, respectively). Recapture rates were similar between the sexes and over both sexesand all diets averaged 3.6%, 3.2%, and 0.6% for release distances of 10, 25, and 50 m, respectively. Pre-releasediet had a significant effect on recapture probability for releases at 10 and 25 m: flies fed sugar only or proteinhydrolysate-rich diet for only 3 d were captured more frequently than flies that had longer access to yeast extractprior to release.

Development of an effective and safe detection or control system is important for pestmanagement. Attractants for male fruit flies, e.g., methyl eugenol (ME), are currently being used in fruit fly control in combination with insecticides. A single formulation that possesses both attraction and killing properties would improve control methods and cost effectiveness. We previously observed the attraction of oriental fruit flies to a basil plant in a yard and confirmed the attraction ofmale fruit flies to basil oil (BO) in the laboratory. Subsequently,we identified insecticidal compounds fromBO that killed three species of tephritid fruit flies in the laboratory, and we also discovered physiological interactions between BO constituents and male attractants. Based on these observations,we developed a single package of basil oil and methyl eugenol (BO + ME) formulation that possesses “attract and kill” properties in combination with a modified AWPM standard trap for field application. The effectiveness of this system is dependent on the type of trap and weather conditions (sunny or not sunny). Any attracted flies were killed within 2 h after entering the BO + ME trap. The combination of BO,ME, and a clear bucket trapmay be a novel alternative for a cost effective and environmentally friendly fruit fly management system.
