Abstract BACKGROUND Apolygus lucorum is one of the most important piercing‐sucking insect pests tea plant In this study, we assessed attractiveness basil plants to A. and effectiveness Ocimum gratissimum L. in control lucorum. The efficiency main volatile chemicals emitted from O. flowers was also evaluated. RESULTS Among seven varieties, more attractive adults selected as a trap assess its effects on natural enemies plantations. population density strips plantations significantly higher than that at 10–20 m away strips. Intercropping with plants, high‐density reduced levels. Eucalyptol, limonene, β ‐ocimene, linalool were four dominant components flower volatiles, their emissions showed gradual upward trend over sampling period. Olfactometer assays indicated eucalyptol dodecane attraction . High numbers recorded eucalyptol, myrcene‐baited yellow sticky traps field trials which 11 volatiles by CONCLUSION Our research aromatic could attract planting has potential pest biocontrol method manipulate populations © 2024 Society Chemical Industry.
