Abstract: The structures of mono-fluoro analogues of (E)-β-farnesene (EBF), the main component of the aphid alarm pheromone of many aphid species, were compared with EBF using AccuModel and PowerFit software. The structures of EBF04, EBF05 and EBF12 with the lowest fitting energy are more similar to EBF. The lowest energy structures of eleven analogues of non-farnesene were also studied. The results indicated that the direction of the numerical value of torsion angle, especially H25-C4-C5-C1 and C5-C6-C7-C8, plays an important role in the compounds activity of alarm pheromone.

Key words: aphid alarm pheromone, (E)βfarnesene, nonfarnesene, structureact ivity relationship
