The Euzophera pinguis sex pheromone as an important tool for IPM strategies

The olive pyralid moth (OPM) Euzophera pinguis Haworth (Lepidoptera: pyralidae) is considered to be one of the most harmful olive grove pests in Spain, Portugal, and many North African countries because it is difficult to control with insecticides. Olive pyralid moth larvae feed on the cambium of the olive tree and as result, tree vigour is heavily reduced.

The insect overwinters beneath the bark as a larva and the first adults emerge in late March, continuing their first flight period until mid-June. After the first oviposition period, a second flight period occurs in late August to early October. Many eggs are laid in crevices and frass accumulations. Thus, hatching larvae can quickly penetrate into the host branch and any open wounds are prone to infestation. Management of this pest is restricted to the use of synthetic insecticides but as the larvae are inaccessible it has proven ineffective, expensive and may lead to undesirable effects.

During the past ten years our group developed basic and applied research for the use of semiochemicals against high populations of this pyralid. The female of this species emits a two-component pheromone blend consisting of (Z,E)-9,12-tetradecadien-1-ol and (Z,E)-9,12-tetradecadienyl-1-acetate (Ortiz et al., 2002) and traps baited with a blend were found to be highly attractive to male moths and remained so for at least 4 weeks. After determining the most effective pheromone blend under field conditions and trap design, the E. pinguis monitoring is accepted as an integral and routine part of IPM of this pest with a high reduction in insecticide application. Synthetic pheromone has been found to disrupt the male moths ability to locate pheromone point sources in small trials and have caused reductions in treated fields (Ortiz et al., 2004) against E.pinguis.
