    Notes: Abstract Two experiments have been carried out to verify the effect of ethylene on the primary attraction ofPhloeotribus scarabaeoides under both laboratory and field conditions. The experiments were based on the enhancement of ethylene production by olive branches and trunks after the application of (2-chloroethyl)phosphonic acid. Under laboratory conditions, the beetles' response was strongly stimulated on the treated branches. Under field conditions, the treatment aided the location of the olive wood by the flying beetles, and the attack density was significantly greater in the treated wood at the end of the experiment.

    Release of ethylene from pruned olive logs: Influence on attack by bark beetles (Coleoptera, Scolytidae) (1994)
    Springer
    Journal of chemical ecology 20 (1994), S. 2513-2521

    ISSN: 1573-1561
    Keywords: Semiochemicals ; kairomones ; ethylene ; ethrel ; Olea europaea ; olive tree ; Phloeotribus scarabaeoides ; Coleoptera ; Scolytidae

    Notes: Abstract In recently pruned olive logs, an increase in ethylene release has been observed between 48 and 72 hr after pruning. The values reached, as well as the duration of ethylene release, varied greatly from one log to another. PioneerPhloeotribus scarabaeoides females have shown a preference for logs in which ethylene emission was higher. In logs treated with ethrel, a significant increase in ethylene emission was observed, together with a greater period of release. Therefore, the use of logs treated with ethrel could be of great importance in the control of this pest of olive trees.
