Food-baited traps are an important part of early detection programs for invasive tephritid fruit fly species, as they are attractive to both sexes of all targeted species. Torula yeast borax (TYB) mixture is a standard food bait, but its longevity is limited (1-2 weeks). Synthetic food-based lures have been developed, including ammonium acetate, putrescine, and trimethylamine. However, the different formulations of these synthetic lures vary greatly in their attractiveness and longevity. Here, we present the results of field trapping in several Central and South American countries as well as Hawaii that compared captures of , spp., and in traps baited with torula yeast borax, which was replaced weekly, versus traps baited with newly developed vial-lures, which contained the same three components noted above and were not replaced over 6-10 weeks of trapping. In all countries, captures of . in vial-lure-baited traps were equal to or greater than captures in TYB-baited traps. However, the vial-lures attracted fewer . than TYB, and data were inconsistent for spp. The implications of these results for large-scale detection programs are discussed.
食物诱捕器是入侵实蝇类果蝇早期检测计划的重要组成部分，因为它们对所有目标物种的雌雄个体都具有吸引力。圆酵母硼砂（TYB）混合物是一种标准食物诱饵，但其有效期有限（1至2周）。已经开发出了基于合成食物的引诱剂，包括乙酸铵、腐胺和三甲胺。然而，这些合成引诱剂的不同配方在吸引力和有效期方面差异很大。在这里，我们展示了在几个中美洲和南美洲国家以及夏威夷进行的田间诱捕结果，该结果比较了每周更换诱饵（圆酵母硼砂）的诱捕器与使用新开发的小瓶引诱剂（包含上述相同的三种成分且在6至10周的诱捕过程中不更换）的诱捕器中，[具体果蝇物种名称1]、[具体果蝇物种名称2]和[具体果蝇物种名称3]的捕获量。在所有国家，使用小瓶引诱剂的诱捕器中[具体果蝇物种名称1]的捕获量等于或高于使用TYB诱饵的诱捕器。然而，小瓶引诱剂吸引的[具体果蝇物种名称2]比TYB少，并且对于[具体果蝇物种名称3]的数据并不一致。本文讨论了这些结果对大规模检测计划的影响。
