Abstract: Lures can stimulate the behavioral responses of fruit flies to a certain extent and play an important role in the green prevention and control of fruit flies. As one of the most important lures, and coming from some plant volatiles or parapheromones, male lures of fruit flies have a significant attractive effect on male fruit flies. Male fruit flies will not only be attracted by the smell of male lures but also feed on the lures, which will be metabolized into different substances in male adults, and then play the corresponding function. In this review, combined with the studies on the feeding effects, we reviewed the research progress of six male lures of fruit flies, namely methyl eugenol, raspberry ketone, zingerone, cuelure, 3-hydroxy-α-ionone and β-caryophyllene, and their metabolism, mainly including the feeding behavior and metabolic changes of male fruit flies, the influence of feeding effect on the behavioral responses of fruit flies, the attractive effect of male fruit flies fed on lures on female and male fruit flies, and the change of mating success rate. In the exploration of the feeding effect, rectal gland is the focus of pheromone isolation and storage, and the waxy, water-resistant film composed of hydrocarbons covering insect body surface is also a potential focus of research. At the same time, exploring the role of antennae and maxillary palp in the lure perception process of fruit flies will help to reveal the complex mechanism behind feeding phenomenon more comprehensively and profoundly. It is expected to provide new ideas and guidelines for the development of fruit fly lures and add more diversified means and approaches for the green ecological prevention and control of fruit flies.
