| Abstract: | In 2002 and 2003, six field experiments were conducted at three olive groves of southern Spain in order to compare the effects
of two types of ethylene treatments (sprayed and diffusers) on the olive losses caused by the olive moth (Prays oleae Bern.) as well as on the activity and effectiveness of oofagous predators. Both treatments showed to be effective to control
the pest; in the two years studied the mean reduction in final infestation due to ethylene was of 35% with respect to the
controls trees, and none affected negatively the action of natural predators of P. oleae. In addition, the use of diffusers set on the trees at the end of flowering period will help the farmers to overcome the
problems of determination of optimum time for sprayed treatments of ethylene. |
