| Abstract: | The Annona fruit borer, Cerconota anonella Sepp., is a serious agricultural pest in many tropical areas of the world. The identification of an attractant for male C. anonella could offer new methods for pest detection and control. A mixture of compounds extracted from female C. anonella elicited antennal depolarization in the male borer. These compounds were identified as octadecanal, 1‐octadecanol, octadecyl acetate, (Z)‐octadec‐9‐enal (Z9‐18:Ald), (Z)‐octadec‐9‐en‐1‐ol (Z9‐18:OH) and [(Z)‐octadec‐9‐enyl] acetate (Z9‐18:Ac) by one‐ and two‐dimensional gas chromatography–mass spectrometry. In laboratory bioassays, synthetic individual compounds as well as synthetic mixtures were found to be attractive to males. In addition, field tests using Delta traps with 1 mg of the ternary mixture composed of Z9‐18:Ac, Z9‐18:Ald and Z9‐18:OH in the ratio of 1 : 3 : 5 caught as many males as traps containing virgin females. The ternary mixture of Z9‐18:Ac, Z9‐18:Ald and Z9‐18:OH was identified as attractant to C. anonella males and can be used to detect and control populations of this insect in Annonaceae plantations. |
