Embodiment 1

[0012] A sex pheromone R-(+)-limonene of Bactrocera citrus was obtained through the following research: the volatile substances released by female adults of Bactrocera citrus were collected by headspace adsorption-solid-phase microextraction method, and the volatile substances released by gas chromatography- Mass spectrometry (Agilent 6890N-5975B type GC-MS) analysis, according to the comparison and analysis of the library spectrum and the retention time of the standard sample, the volatile component R-(+)-limonene was identified.

[0013] In July 2015, a field luring test of fruit fly pests was carried out in an orangery. R-(+)-limonene and undecyl alcohol were diluted 100 times with liquid paraffin, and then loaded into the lure core of the trap with sweet and sour liquid bait In the process, hang them randomly and evenly in the orangery, check the number of male and female Bactrocera citrus and Bactrocera citrus on the first day after the trap is placed, and check every 2 da...
