| Abstract: | The red palm weevil, Rhynchophorus ferrugineus (Olivier) (Coleoptera, Curculionidae), has been present in Andalusia since 1993 although its major expansion began in 2005. Currently, the implementation of an action protocol against the red palm weevil based on curative and preventive treatments has a high cost. The aim of this work is to establish a minimum frequency between preventive treatments that would reduce costs. Three frequencies of application were evaluated (at 45, 60 and 90 days).The results show that preventive treatments can decrease the reproductive potential of the pest, but do not prevent the infestation of palm trees. Preventive treatments every 60 days effectively reduce costs and increase the survival of the palm trees. |
