Tephritid fruit flies require protein for sexual and gonotrophic development. Food-based lures are therefore widely used in strategies to detect and control fruit flies in the Tephritidae family. However, these baits are attractive to a broad range of insect species. We therefore sought to identify volatiles detected by the fly antennae, with the goal to compose lures that more specifically target tephritids. Using gas chromatography-coupled electroantennographic detection (GC-EAD) we screened for antennal responses of four important tephritid species to volatile compounds from five commercially available protein-based baits. Antennal active compounds were reconstituted in synthetic blends for each species and used in behavioral assays. These species-based blends were attractive in olfactometer experiments, as was a blend composed of all antennally active compounds from all the four species we observed (tested only in , Hendel). Pilot field tests indicate that the blends need to be further evaluated and optimized under field conditions.
实蝇科果蝇的性发育和生殖营养发育需要蛋白质。因此，基于食物的诱捕剂被广泛应用于实蝇科果蝇的检测和控制策略中。然而，这些诱饵对多种昆虫具有吸引力。因此，我们试图识别果蝇触角检测到的挥发物，目标是配制出更具针对性地针对实蝇科果蝇的诱捕剂。我们使用气相色谱-触角电位检测联用技术（GC-EAD），筛选了四种重要实蝇科果蝇对五种市售蛋白质诱饵中挥发性化合物的触角反应。将触角活性化合物重新配制到每个物种的合成混合物中，并用于行为测定。这些基于物种的混合物在嗅觉仪实验中具有吸引力，我们观察的所有四种果蝇的所有触角活性化合物组成的混合物（仅在亨德尔进行测试）也是如此。初步田间试验表明，这些混合物需要在田间条件下进一步评估和优化。
