[Objectives]  To compare the numbers of natural enemies of corn pests attracted by trans-β-farnese, nerolidol, 6-methyl-5-heptene-2-one, cis-3-hexene acetate, eugenol, linalool and cis-jasmonanone in corn fields, and thereby inform the biological control of insect pests in corn fields. [Methods]  Water basin traps, sticky plates and the five point sampling method were used to quantify the abundance of predators and parasites of corn pests on 100 corn plants, and thereby compare the attractiveness of the seven plant volatiles to these species. [Results]  There were significant differences in the attractiveness of nerolidol to Anterhynchium (D.) flavomarginatum, of cis-jasmonanone to Episyrphus balteatus, and of trans-β-farnene and cis-jasmonanone to Propylaea japonica, compared to the other five compounds and the control. In a plot experiment, nerolidol and cis-jasmonanone were more attractive to E. balteatus and Harmonia axyridis, and nerolidol more to E. balteatus and Astochia virgatipes, than the control. [Conclusion]  Of the seven plant volatiles tested, nerolidol was the most attractive to the natural enemies of corn pests, followed by cis-jasmonanone and trans-β-farnese.
