Welcome

Red Palm Weevil (RPW), Rhynchophorus ferrugineus (Coleoptera: Curculionidae) is considered by FAO as the most important and destructive pest of palms, with spread in countries of Oceania, Asia, and the Mediterranean. In Cyprus, RPW was first recorded in 2006 on Phoenix canariensis and Ph. dactylifera. Today, the insect is found throughout the island. Up to date, RPW has destroyed hundreds of palms, mainly of the abovementioned species in the island. In Cyprus the problem of palm infestation by insect pests could increase, as since 2006 two more new species were detected. The first species the palm borer Paysandisia archon (Lepidoptera: Castniidae) was initially detected in 2008 with on palms of Chamaerops humilis, Washingtonia filifera and Phoenix roebelenii and the second species the nipa palm hispid Octodonta nipae (Coleoptera: Chrysomelidae) was only found in 2010 on Queen palms. Since then, extensive surveys and eradication measures have been adopted for their elimination. Nevertheless, management of such insect species internationally and locally (in Cyprus) can be very difficult (cryptic life cycle) and expensive, as their control is carried out mainly through the use of phytosanitary and cultivating measures, trapping, and the use of chemical compounds.
