Bemisia tabaci is a polyphagous pest that transmits various viruses, including tomato yellow leaf curl virus (TYLCV) while feeding on crops. Prior to identifying attractants of B. tabaci, the pheromone biosynthesis activating neuropeptide (PBAN) sequence was obtained via transcriptome analysis of female adults. After injecting artificially synthesized PBAN into the female adults, the compounds contained in the female adults were extracted using hexane, and gas chromatography-mass spectrometry (GC-MS) was performed. As a result, 22 compounds showed quantitative differences after PBAN injection. Among them, it was confirmed that B. tabaci is attracted to 2-ethylhexanoic acid and phytol. These results suggest that 2-ethylhexanoic acid and phytol can be used as attractants for the control of B. tabaci.
