IN SYNTHESIS…

  • Attacks palm trees, specially the Canary Island palm (Phoenix canariensis) and the date palm (Phoenix dactylifera). Other important hosts are Washingtonia sp. Cocos nucifera, etc.
  • It is necessary to monitor the symptoms of an infestation to detect the pest as earlier as possible. Some of these symptoms are: loss of symmetry in the crown or young leaves from the tip, leaves fall, grinded fibres presence in inferior areas and/or eaten leaves, injuries and holes in the crown basis and trunk.      
  • The adults are attracted by the volatile substances emanated from the host plants, basically from the cat palms. 
  • Its life cycle includes the egg, larva, pupa and adult stages,  which can be all together at the same moment, and it has a duration, depending on the climate conditions, between 3 and 4 months (three generations per year)
  • The monitoring by traps with aggregation pheromones is essential to detect the weevil presence, determinate the pest stage and carry out a monitoring of the populations and value the risks level.
  • The management by baited traps with aggregation pheromones is an effective tool to keep the population levels of this pest under the tolerance level.
